CONTROL INPUTS AND CONTROL OUTPUTS PORTS A - D

General:

Operation see page 21
(PORTS C, D are optional)
Each of the 4 ports (A, B, C, D) have 4 inputs and 4 outputs and a power source for supplying floating control keys or
contacts.
The inputs and outputs are galvanic insulated from the DMM 4650 and the adjacent control lines. Port A has an
additional fault output (relay contact) which, during normal operation, is always closed.
The DMM 4650 provides port connection through 25-pole sub-D connectors (male).
Pin assignment for ports A, B, C, D:

Control levels and currents:

Power source -Batt. / +Batt. corresponds to a supply voltage of (20V - 31 V) of the DMM 4650. For current limita-
tion (fuse), a PTC resistor (positive temperature coefficient resistor) is provided at the +Batt connection of each
port.

Inputs:

The polarity of the control inputs is random.
