SREXP Safety Expansion Modules

Expand your safety systems implemented with SR1 modules, adding additional safety contact in a modular manner. The SR105E provides signaling contacts for fault monitoring and can be used in systems up to safety category 4, PL e.

• Power requirements—the SR106ED will accept 24 VAC/DC
• Outputs—the SR106ED has 3 N/O delayed outputs to route power to the coils of power contactors (delay selectable from 1 to 30 sec.)
• Outputs—the SR105E has 3 N/O outputs to route power to the coils of power contactors plus 1 N/C auxiliary output for monitoring by the safety monitoring relay
• Auxiliary Output—the SR106ED has 1 N/C auxiliary for monitoring by the safety monitoring relay
• PLC Compatible—The N/O off delayed output makes it possible to use the SR106ED on machines with Programmable Logic Controllers that require some time to execute an orderly shutdown.
