Switch Input Module

Features

The ES-Key 18 digital, 3 output, with 1 analog input module is a Class 1 ES-Key network module designed for use in a ES-KeyTM electrical system network. This module has eighteen (18) configurable polarity inputs (positive or ground), three configurable outputs (positive or ground) , and one (1) analog input (0-5 volt or 4-20mA). The inputs are reported to the ES-Key network via J1939 CAN messages and can be tied to desired functionality through the ES-Key database by using the ES-Key professional software.
