    - Vers. 1.0 OVERVIEW eloProg is a modular safety controller. It consists of a master unit (485EPB), which can be configured using the configuration software graphic interface, and a number of expansion units connected via the proprietary bus. The master unit can also be used as a stand-alone device. It has 8 safety inputs and 2 independent programmable dual channel outputs.
