FCT18-CR Bistable Time Relay with Control Signal On
Dual-Stable State Control with Precision Timing and Signal Trigger
Product Overview
The FCT18-CR is a bistable time relay with control signal on functionality. It features two stable states and is controlled by an external signal. Upon power-up, when the control signal S is applied, the relay contact R closes. A new control signal S will then open the contact R. This relay provides precise timing control for industrial automation systems requiring bistable state switching with signal trigger.
