D 244 031 00 (equivalent to Beckhoff EL1859)

D 244 031 00 | HD EtherCAT Terminal, 8-channel digital input + 8-channel digital output 24VDC

The digital D 244 031 00 EtherCAT Terminal combines eight digital inputs and eight digital outputs in one device. The inputs have a filter of 3.0 ms. The outputs process load currents up to 0.5 A, are short-circuit-proof and protected against polarity reversal. The signal states are displayed by LEDs.

The reference ground for all inputs is the 0V power contact, the outputs are fed via the 24V power contact. The conductors can be connected without tools in the case of solid wires using a direct plug-in technique.

The HD EtherCAT Terminals (High Density) with increased packing density feature 16connection points in the housing of a 12mm terminal block.
