EL1104, EL1114 | 4-channel digital input terminals 24 V DC, 24 V and 0 V sensor supply
The EL1104 and EL1114 digital input terminals acquire the binary control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation unit. The EL1104 and EL1114 versions have input filters of different speeds. The EtherCAT Terminals contain four channels that indicate their signal state by means of light emitting diodes.
