Application Details

Safetyrelay expansion module ESR-4A2B-E supply4 safetycontacts output and 2 auxiliary output in safety circuit. Connect A1 of ESR-4A2B-E to output terminal of the previous device,A2 connected the pole of power supply, when previous device send rightsignal, the related contacts ofexpansion module has corresponding action.|

Automatic resetSafety feedback loop

●ESRE-4A2B: Connect A1,A2 of ESRE-4A2B as diagram, when previous device output active signal, the component works.

●Input circuit output active signal to ESRE-4A2B, K1 & K2 of relay get energized and held, indicator CH1, CH2 light up, safety contacts 13-14/23-24/33-34/43-44 close, and auxiliary Y1-Y2/ 51-52 contacts open.

●Connect YS, Y2 in series to feedback loop of previous device, when a related fault occurs, the safety relay expansion module will not perform the corresponding action.

●The input circuit is disconnected (The input circuit has no valid signal output to the safety relay expansion module), relay K1, K2 are disconnected, indicator light CH1, CH2 are off, safety contacts 13-14/23-24/33-34/43-44 are disconnected, andauxiliary contacts Y1-Y2/51-52 are closed.


 Product Installation
Please cut off the power supply when mounting, and ensure no dangerous voltage of machine, except the lighting device and spare sockets; Clip the product directly onto 35mm rail inside the equipment cabinet. Before powering on, please check to ensure cable connection is correct and the product is fastened to the mounting rail.Before disassembling the product, you must cut off the power supply to the machine, then loosen the locking screws or remove terminals.
