The ELCB controllers are the simplest and most affordable members of the ELC portfolio. With ELCB, the focus is on just enough control for applications up to 40 I/O points. These controllers pack a lot into a small, low-profile package. Like the ELCM controllers, these controllers are AC powered and provide 24 Vdc sensor power. But unlike the rest of the ELC family, the ELCB controllers do not offer expansion I/O. The ELCB is great as a standalone controller, or is capable of networking with other controllers, operator interfaces, drives, or other Modbus serial devices.
