Posted 18 Sep 2018 (edited) ES or ESS is only indicating the power supply of the unit (low voltage DC or high voltage AC), so there should be no problem except you need to change the supply wires and type. Edited 18 Sep 2018 by kaare_t Wrong answer Share this post Link to post Share on other sites
Posted 18 Sep 2018 I would say that the MT/ES is a 100-240VAC PLC Transistor (SINK) output. The MT/ESS is also a 100-240VAC PLC, but with Transistor (SOURCE) output. 24VDC models with transistor output is named MT/DS for Sink, and MT/DSS for Source outputs. 1 person likes this Share this post Link to post Share on other sites
