EL2535 | 2-channel pulse width current terminals 24 V DC

The EL2535, EL2535-0050 and EL2535-0002 output terminals control the output current via pulse width control of the supply voltage. They are galvanically isolated from the E-bus. The current value 0 up to maximum output current (±1 A, ±50 mA, ±2 A) is specified by the automation device via a 16 bit value. The output stages are protected against overload and short-circuit. The EtherCAT Terminals have two channels that indicate their signal state via light emitting diodes. The LEDs simplify local diagnosis by displaying typical load and wiring faults.
