12. PORT A

4 control inputs and 4 trigger outputs

1 fault output (alarm on defect of the appliance)

1 ±24V DC, 90 mA power source

11. REMOTE

The 9-pole D-SUB connector “Remote-Control RS-232" is a serial computer interface for data transfer and service functions.

PORT A-D

All inputs and outputs are provided in 2-pole floating design and isolated from the DMM 4650 circuitry and adjacent lines.

13. PORT B

Control inputs, trigger outputs and ±24 V DC

14. PORT C

Control inputs, trigger outputs and ±24 V DC

* optionally retrofitted

Each input is realized as an AC opto-coupler (AC floa- ting polarity).

Each output has a floating relay contact.

Each port connector (DB 25) has 4 inputs, 4 outputs, and per port +24 V line and ground potential conductors.

By means of the 24 V DC voltage, it is possible to connect external floating control keys as well as con- tacts directly.
