SNAP Mechanical Power Relay Output Module

Switch loads up to 250 VAC, 6 A

SNAP mechanical relay output module switches loads up to 250 VAC, 6 A

This SNAP mechanical power relay output module can switch loads up to 6 amps at 250 VAC or 30 VDC.

The SNAP-OMR6-C is SPDT (Form C): each of the four mechanical contacts can be used as normally open or normally closed. Your choice.


  • Four channels per module, each switching AC or DC power
  • Channel-to-channel isolation and optical isolation
  • Each channel can carry 6 amps
  • Each channel presents a true open circuit when off

Mount the new mechanical power relay module on a SNAP PAC rack alongside other analog, digital, and serial I/O modules. Use a SNAP PAC brain or rack-mounted controller for communications and I/O processing.

Or use this module with legacy SNAP brains—SNAP Ultimate, SNAP Ethernet, SNAP Simple, B3000, B3000-B—and B-series or M-series racks.

SNAP PAC rack with SNAP I/O modules and rack-mounted controller

Use SNAP I/O in three ways:

Connected to an Opto 22 control system. With a SNAP PAC programmable automation controller and PAC Project industrial control software, SNAP I/O distributes local intelligence to the I/O level for greater system efficiency.

As intelligent remote I/O in another system. Connect to Allen-Bradley industrial PLC systems, use the built-in Modbus/TCP protocol, or use OPC to exchange data with other manufacturers' systems.

For PC-based control. Develop applications in C/C++ or Visual Basic using a free Opto 22 Software Development Kit. Or use SNMP to send traps to a network management system, SMTP to email alarms and conditions, or PPP to communicate remotely over a modem.
