EL2878-0005 | 8-channel digital output terminal 24 V DC, flat-ribbon cable connection, integrated diagnosis of supply voltage

The EL2878-0005 digital output terminal offers a very compact design with its 8 channels. It is thus suited for example for multi-pin connector valve terminals. A 20-pin connector enables the secure connection of plug connectors using insulation displacement contact, as is usual for ribbon cables and special round cables. This significantly simplifies the wiring of many channels. State-of-the-art output drivers guarantee minimum power dissipation. 8 LEDs display the logical signal states of the outputs. The terminal analyses the supply voltage and reports the status via process image and LED.
