Key Features
- 8 digital input channels rated at 120V AC/DC
- Designed for AC/DC proximity switches and on/off devices
- Wide operating voltage range: 87-138 VAC or 97-138 VDC
- 1771-WA wiring arm allows module replacement without rewiring
- Optoelectrical isolation protects system circuits from transients
- Input filtering reduces electrical noise interference
- 8 orange status LEDs for field-side indication
- Supports ½, 1, and 2-slot I/O addressing
- Keying bands between pins 10-12 (upper) and 4-6 (lower)
- Low backplane current draw at 75 mA
Installation Notes
Install the module in a 1771 I/O chassis containing a PLC processor. Use keying bands to ensure proper slot placement: between pins 10 and 12 for the upper connector and between pins 4 and 6 for the lower connector. Connect field wiring using the 1771-WA wiring arm, which allows module replacement without disconnecting wiring. The module supports ½, 1, and 2-slot I/O addressing configurations. Ensure input devices are compatible with the 120V AC/DC rating and observe the specified signal delay times for AC (24 ms) and DC (10 ms ON, 20 ms OFF) operation.
