EL1024 | 4-channel digital input terminal 24 V DC for type 2 sensors
The EL1024 digital input terminal acquires the binary 24 V control signals and transmits them, in an electrically isolated form, to the higher-level automation system. The EtherCAT Terminal contains four channels that indicate their signal state by means of light emitting diodes. The input signal of the EL1024 corresponds to IEC 61131-2, type 2. Additionally, the 4-channel EtherCAT Terminal enables the direct connection of four 2-wire sensors. Four +24 V connection points are provided.
