Description
Allen Bradley 1771-NOV/C DC Output Module
Configured for discrete DC switching execution in PLC-5 control systems, the Allen Bradley 1771-NOV/C (1771-NOV DC Output Module) provides direct physical/electrical execution for sink-type field device control through the 1771 I/O chassis platform. The module uses solid-state outputs, optical isolation, and front-panel status indication for digital ON/OFF signal handling.

PLC-5 Solid-State Output Interface
The 1771-NOV/C provides discrete output switching between PLC controller logic and external DC field devices. The sink output architecture switches the load path toward ground and requires a positive field supply connection for connected devices.
The module communicates through the 1771 chassis backplane and uses optical isolation to separate field wiring circuits from internal logic electronics. The isolation structure reduces electrical coupling between external loads and PLC control circuitry.
The module belongs to the Allen Bradley PLC-5 industrial control platform and supports deterministic backplane data exchange with compatible processors. Proper chassis slot keying and module placement are required for correct hardware configuration.
Firmware and Backplane Compatibility
The 1771-NOV/C operates as a PLC-5 I/O platform component with chassis-based communication rather than network-addressed standalone operation. System configuration requires verification of processor compatibility, chassis slot assignment, and installed I/O addressing.
The module uses PLC-5 I/O density scaling principles, allowing discrete output expansion through additional 1771 chassis installations. Firmware flash compatibility is not specified for this module generation; configuration is maintained through hardware module selection and PLC controller programming.
Frequently Asked Questions
Q: What type of output signal does the 1771-NOV/C provide?
A: The module provides solid-state DC sink outputs for ON/OFF control of external field devices.
Q: What is the backplane current requirement of the 1771-NOV/C?
A: The module requires 330 mA from the 1771 chassis backplane supply.
Q: Can the 1771-NOV/C be installed with thermocouple modules?
A: The module must not be installed in the same chassis as 1771-IX thermocouple modules. It is compatible with 1771-IXE modules.
Field Installation Guidelines
Install the 1771-NOV/C only in compatible 1771 I/O chassis slots and verify chassis keying before insertion. Use the specified plastic keying bands to prevent installation in unsupported slot configurations.
Connect field wiring according to sink output requirements, maintaining correct polarity between the DC supply and connected loads. Route DC output wiring separately from high-voltage conductors and high-frequency switching circuits to reduce electrical interference.
Apply electrostatic discharge protection when handling the module. Confirm LED status indication after installation and verify output addressing within the PLC controller configuration before placing the system into operation.
