IP4112-Bxxx, IE4112 Signal Connection

4 Channel Analog Outputs, 0 to 20 mA

The actuator is connected via Output +/-. The actuator can also optionally be operated/supplied with 24 V_DC. The shield his capacitatively coupled to the chassis. In order to ensure that interference is effectively dissipated, the chassis must be conductive and earthed through a low resistance.

LED indicators - meanings

There is a green Run LED and a red Error LED for each channel. The Run LED illuminates when data is being transferred to the D/A converter. The red Error LED has no function, and only illuminates briefly during the start-up phase.
The device is functioning correctly if the Run LED is lit and the Error LED is unlit.
