CompactBlock LDX Distributed I/O
|
CompactBlock I/O for DeviceNet
|
ArmorBlock I/O
|
| Features
|
Wide breadth of I/O types that can handle diverse applications
Expandable up to 3 digital expansion blocks (64 I/O's)
Universal sink/source inputs reduces the number of components to stock and allows flexibility of input types
Selectable termination types (D-shell or screw)
Easy to connect and configure using modular EDS files
ODVA conformance ensures high level of interoperability with other DeviceNet products
Analog DeviceNet bases for current, voltage, PT100 and thermocouple execution
CompactBlock LDX I/O are also available for other network
24V DC, 120V AC and relay discrete blocks with built-in DeviceNet adapter
Cyclic and change-of-state messaging increases network throughput, increases productivity
Auto baud rate detection
|
10…30V DC device power accommodates a broad range of applications
IEC/NEMA Type 3+ inputs offers widest range of compatible sensors
Removable terminal blocks reduces maintenance cost
Output short-circuit protection
Hardware watchdog function
Includes DeviceLogix Smart Component Technology enabling localized, simple control functions
Compact size of I/O block
Autobaud detection
Rotary node address switches
Selectable input filters
Change-of-state operation
ODVA conformance ensures high level of interoperability with other DeviceNet products
RIO and other network bases are also available
|
Sealed housing rated for IP67K and NEMA 4X eliminate enclosure costs
I/O connectors are sealed M8 pico or M12 DC micro styles
8-point and 16-point self-configuring I/O provides flexibility for any input/output combination
Removal and Insertion Under Power allows module replacement without impacting the network operation
Isolated auxiliary power maintains power to the outputs if main power fails
Outputs electronically protected from failing with option to auto-restart or latch off
Complies with Open DeviceNet Vendor Association, Inc. (ODVA) conformance test software
