PLC-5 Discrete Input Interface Characteristics
The 1771-IND module provides AC/DC digital input processing for Allen-Bradley PLC-5 control architectures. The module supports 16 field input points and converts external switching signals into controller-readable digital states through the 1771 backplane interface.
The module uses Allen-Bradley PLC-5 I/O density scaling methods for rack-based installations. Its backplane communication structure supports deterministic data exchange between the input module and PLC processor. The 1771-WH wiring arm provides the field connection interface for installation and maintenance operations.
Frequently Asked Questions
Q: What voltage levels can the 1771-IND accept?
A: The module accepts 16-30 VAC input signals and 9-30 VDC input signals within the specified operating range.
Q: How many input channels are available on the module?
A: The 1771-IND provides 16 digital AC/DC input channels.
Q: What backplane power requirement does the module have?
A: The module requires 250 mA from the PLC-5 1771 backplane supply.
Field Installation Guidelines
Install the 1771-IND module into a compatible Bulletin 1771 I/O chassis slot after disconnecting backplane power. Connect field wiring through the supplied 1771-WH wiring arm.
Route AC/DC input conductors separately from communication and low-level signal wiring to reduce electrical interference. Verify field voltage compatibility before connecting external devices.
Maintain proper cabinet grounding and follow PLC-5 system installation procedures for rack assembly, wiring separation, and module replacement operations.
