Rockwell 0-60066 Relay Output Module

The Rockwell 0-60066 is an 8-channel relay output module designed for PLC and remote I/O systems. This module provides isolated form C relay contacts for switching AC and DC loads up to 2A, making it suitable for controlling contactors, solenoid valves, motor starters, and alarm indicators in industrial automation applications.

Relay Output Design

Each of the 8 relays features silver alloy contacts for reliable switching in industrial environments. The form C (SPDT) configuration provides both normally open and normally closed terminals, allowing flexibility for fail-safe or normally energized applications. The module includes snubber circuits across the contacts to reduce arcing when switching inductive loads, extending relay life.

Diagnostics and Indicators

Individual red LEDs on the front panel clearly indicate the energized state of each relay, allowing rapid visual verification of output status. The module also features a green power LED and a red communication/error LED. The module can report relay contact weld or coil failure diagnostics to the host controller when used with compatible PLC systems.

Application Domains

The 0-60066 is ideal for applications requiring isolated, high-voltage switching capability. Common uses include motor starter control, valve actuation, solenoid control, alarm annunciation, and lighting control in factories, buildings, and infrastructure systems. The module is compatible with a wide range of PLC backplanes and fieldbus couplers.
