EL1862, EL1872 | 16-channel digital input terminals 24 V DC, type 3, flat-ribbon cable connection

The EL1862 and EL1872 digital input terminals offer a very compact design with their 16 channels. 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. The input characteristic conforms to the type 3 specification and guarantees minimum power dissipation. 16 LEDs display the logical signal states of the inputs.
