EL2014 - Introduction

Four-channel digital output terminal, 24 V_DC, 0.5A, with diagnostics

The EL2014 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. The EL2014 is protected against polarity reversal and processes load currents with outputs protected against overload and short-circuit. The integrated diagnosis 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. The output behavior of the channels in the case of a bus error can be parameterized. The switching state and any error of the output are indicated by the LED. Maintenance of the application is simplified by the diagnosis. The power contacts are continuous; reference potential of the outputs is the 0 V power contact.

The outputs are fed via the 24 V power contact in the EL2014.
