EL1094 | 4-channel digital input terminal 24 V DC, ground
switching
The EL1094 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the
higher-level automation unit. Four 2-wire sensors can be connected to the EL1094. The EtherCAT Terminal indicates its signal state by means of light
emitting diodes.
