The digital EL1852 EtherCAT Terminal combines eight digital inputs and eight digital outputs on a single device. The signal state of the channels is indicated by LEDs. The EL1852 offers a high packing density with 16 channels. 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.

Special features:

• compact design through the combination of inputs and outputs in one terminal
• no bouncing due to mechanical switches thanks to 3 ms input filter
• short-circuit proof outputs protected against reverse polarity with output current up to 0.5 A
• direct connection of connectors with insulation displacement contacts
