EL1104 | 4-channel digital input terminal 24 V DC, 24 V and 0 V sensor supply

The EL1104 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. The EtherCAT Terminal contains four channels that indicate their signal state by means of light emitting diodes.
