ArmorPoint™ I/O
ArmorPoint is a 24V DC modular On-Machine™ I/O that extends the features and benefits of the POINT I/O™ IP20 system into an IP69K-compliant system. ArmorPoint I/O offers flexibility, ease of application, and just-what-you-need granularity in one to eight points to reduce system cost and size.
Benefits
- Sealed housing rated for IP69K and NEMA 4X eliminates enclosure costs.
- A variety of I/O types for broad application coverage.
- Easy module replacement with unique latching mechanisms eliminates need for screws.
- Connection with industry-standard M8, M12, and M23 quick-disconnects reduces costs of additional accessories.
- Provides tight IP67 motor starter integration with ArmorStart™.
- Extremely fast I/O backplane uses change-of-state (COS) connections to maximize performance (polling available in configuration mode).
- Auto Device Replacement (ADR) allows OEMs to add machine features and I/O modules without making changes to the machine’s control software.
- Removal and Insertion Under Power (RIUP) makes it possible to replace a module without disrupting network operation.
- Efficient network solutions with multiple DeviceNet™ interfaces, ControlNet™, EtherNet/IP™, and PROFIBUS DP communication adapters.
Product Design
The architecture of ArmorPoint is based on the POINT I/O system and reuses the circuitry of the adapter and I/O designs. The system is IP67-compliant and other certifications necessary to provide a complete On-Machine solution. ArmorPoint I/O modules offer one to eight points per module. Choose from many different I/O types with connector choices of M8, M12, or M23 quick-disconnect terminations.
The I/O modules are interfaced to a network through a communication adapter, which includes a built-in power supply that converts incoming 24V DC power to 5V DC backplane power. Communication adapters are available for DeviceNet, ControlNet, EtherNet/IP, and PROFIBUS DP. The I/O modules receive power from the power supply through the backplane. ArmorPoint I/O offers flexibility, supporting up to 63 I/O modules per network node. A bus extension module allows for separation of modules on the same node.
The family includes hardened power supplies to allow for isolation, for example AC from DC, analog from digital, inputs from outputs. Module replacement is easy since modules are held on the base by unique latching mechanisms—no screws needed. ArmorPoint connects directly to ArmorStart™ on the same network node.
Modular Design
ArmorPoint I/O has three major components:
- I/O modules provide the field interface, system-interface circuitry, and bases for mounting
- Communication interface modules provide the network-interface circuitry
- Power distribution modules provide the solution to expandability of the ArmorPoint I/O system and the flexibility to mix a variety of signal types

Communication Adapter Modules
An ArmorPoint I/O communication interface module provides the interface between a network and the ArmorPoint I/O backplane. A terminating base, used with the last I/O module, ships with the adapter. An I/O adapter supports up to a maximum of 63 I/O modules.
Adapter modules are available for ControlNet, DeviceNet (with and without subnet connectivity), EtherNet/IP, or PROFIBUS DP networks. The DeviceNet adapters are available in four styles, based on connectivity: DC micro (M12) terminations, mini passthrough terminations, mini drop termination, and adapter with subnet connectivity.

Specialty I/O Modules
- Counter Modules
- SSI Modules
- Serial Interface Modules (RS–232, RS–485, RS–422)
ArmorPoint Counter Modules
The input voltage range is 5V DC (1738–IJ) or 15…24V DC (1738–VHSC24). The module returns the count or frequency in the form of a 24-bit binary number (0…16,777,215) expressed in a 32-bit word. Each counter has a user-selectable preset and rollover value associated with it.
The operation of the counter and encoder modes is nearly identical. The difference between the two modes is in the type of feedback (one-phase versus two-phase) for the count direction (up or down). In encoder mode, a transition is expected on B for counting to proceed in a direction, whereas, in counter mode, the B input may be left at a static level. All operating modes are selected by writing appropriate configuration data to the module.

ArmorPoint Serial I/O Modules
ArmorPoint Synchronous Serial Interface Modules
The Synchronous Serial Interface Absolute Encoder Module collects serial data from industrial absolute position encoding sensors that use standard SSI protocol, including linear, rotary, and optical distance measuring devices. The module is inserted into an ArmorPoint I/O terminal base that provides common power, communications, and wiring connections for the SSI sensors. The module converts a serial data stream from an SSI sensor into absolute position data readable as a 32-hexadecimal value. Gray or binary-code capable with gray to binary conversion, increasing or decreasing SSI count indication, 2 SSI word comparator values, and SSI word latching with I1 input.
ArmorPoint Serial Interface Modules
The 1738–232ASCM12 and 1738–485ASCM12 serial-interface modules offer a serial-link communication interface solution for peripheral products with RS–232 (use the 1738–232ASCM12), RS–485, and RS–422 ports (use the 1738–485ASCM12). These modules allow a device with serial-interface output (i.e., bar code readers) to communicate up to 128 bytes of ASCII data onto any network supported by ArmorPoint I/O. Each module is a single-channel, full-duplex interface and is rated for up to 38.4k baud. LED indicators on the modules offer diagnostics for the module, POINTBus backplane, and transmit/receive status indication.

Power Supplies
ArmorPoint I/O adapters have built-in POINTBus power supplies. All ArmorPoint I/O modules are powered from the POINTBus by either an adapter or expansion power supply.
For power specifications see Communication Adapter Modules
|
ArmorPoint Expansion Power Unit
The ArmorPoint I/O Expansion Power Unit (1738–EP24DC) passes 24V DC field power to the I/O modules to the right of it. This unit extends the backplane bus power and creates a new field voltage partition segment for driving field devices for up to 17 I/O modules. The expansion power unit separates field power from I/O modules to the left of the unit, effectively providing functional and logical partitioning for:
- Separating field power between input and output modules
- Separating field power to the analog and digital modules
- Grouping modules to perform a specific task or function
Power to the POINTBus backplane and I/O modules is brought in through the auxiliary power connector. You can connect up to 12 I/O modules and an adapter with a maximum of 10 A field power, using the auxiliary power. Additional I/O modules require the use of one or more ArmorPoint I/O 24V DC expansion power units.
|
ArmorPoint Field Power Distributor
The ArmorPoint I/O Field Power Distributor Module (1738-FPD) passes through all ArmorPoint I/O backplane signals, but does not provide additional POINTBus backplane power. The field power distributor gives you the ability to change the field power distribution source for I/O modules to the right of the field power distributor. This facilitates logical or functional partitioning of low-channel count, high I/O mix applications using any of the communication adapters. Use the field power distributor with a broad range of voltage inputs including 5V DC to 250V DC and/or 24V AC to 240V AC applications and I/O modules.

Bus Extension Bases (1738-EXT1, 1738-EXT3)
An ArmorPoint I/O bus extension base allows the backplane to be extended to additional I/O or the ArmorStart IP 67 motor starter. May require the addition of an auxiliary power module. Refer to the installation manual (publication 1738–IN018A) to determine if a 1738–EP24DC or 1738–FPD is needed after a bus extension base.
