CONNECTIONS

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: @ corresponds to A, B, C, D
