Application details

Two hand button control module ESRH-3A1B supply 3 safety contacts output and 1 auxiliary contacts output in loop. Connectthe A1 terminal to positive of DC24V power supply, A2 terminal to the negative of power supply, when the signal of input loopS11 S21 is correct and reset loop active, the two hand button control module works.

Automatic resetInput loop

●ESRH-3A1B: connect Y1-Y2.

●When input loop S11 and S21 input active signal, component start to work.

●When input loop input active signal to two hand button, reset loop active, the K1 K2 of relay keep disconnecting, indicator light CH1 CH2 light on, safety contacts 13-14/23-24/33-34 close, auxiliary 41-42 disconnected.

●Dual-channel input, connect S11 & S21 of relay to two handbutton respectively, at the mean time connect NO/NC of twohand button as diagram.

●Input loop disconnect (Input loop without active signal to ESRH-3A1B), reset loop active, the K1 &K2 of relay get disconnected,indicator CH1, CH2 light off, safety contacts 13-14/23-24/33-34get disconnected, auxiliary 41-42 close.

 Product Installation
