The next member of the ELC portfolio of controllers is the ELCM. This midrange family comprises brick style controllers, with expansion I/O modules. These all-in-one controllers combine inputs, outputs, logic processing and an integrated AC power supply into a compact package but also provide the means to expand as applications change or grow. The controller also provides 24 Vdc power for sensors, eliminating the space, wiring and expense of an additional power supply. And with three communication ports, the ELCM is able to interface into a local operator interface, connect to other controllers or supervisory computers and still maintain an open port for programming.
