EL1872 | EtherCAT Terminal, 16-channel digital input, 24 V DC, 10 µs, flat-ribbon cable
The EL1872 digital input terminal offers 16 channels in a very compact design. A 20-pin contact strip 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 signal states of the channels are indicated by LEDs. The power contacts are connected through.
Special features:
- input specification type 1/3
- low delay due to fast 10 µs input filter
- usable, for example, for inductive or capacitive sensors
- direct connection of connectors with insulation displacement contacts
