Counter Modules
The POINT I/O Counter/Encoder modules return 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 counter mode only accepts single-phase inputs. The encoder mode only accepts 2-phase quadrature inputs.

| 1734-SSI | 1 Encoder channel | 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 a POINT 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. | 110 mA | 10…28V DC, 0.75 A max |
0.94 W | 1734-TB, 1734-TBS |
| 1734-232ASC | 1 Serial Interface channel | The 1734-232ASC and 1734-485ASC serial-interface modules offer a serial-link communication interface solution for peripheral products with RS-232 (use the 1734-232ASC), RS-485, and RS-422 ports (use the 1734-485ASC). 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 POINT 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. | 75 mA | 10…28V DC 1.0 A max |

Address Reserve Module
| Cat. No. | Description | PointBus Current (mA) | Power Dissipation, Max. | Terminal Base Unit |
| 1734-ARM | The Address Reserve Module is a single-slot 12 mm wide smart slot filler. Use the module to retain a node address for later insertion of any future option. | 75 max @ 5V DC | 0.375 W @ 5V DC | 1734-TB, 1734-TBS |
