Introduction

Four-channel digital output terminal, 24 V_DC, 2 A, with extended diagnostics

The EL2044 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation.

The EL2044 is protected against polarity reversal and processes load currents with outputs protected against overload and short-circuit. The integrated diagnostics can be evaluated in the controller and is indicated by the LEDs. Overtemperature and the lack of a voltage supply to the terminal are supplied as diagnostic information. Beyond that each channel can among other things signal a short circuit individually. Maintenance of the application is simplified by the diagnostics.

The power contacts are connected through. The outputs are fed via the 24 V power contact in the EL2044.
