Supply Voltage And Control Inputs/Outputs - HBM MP85A Operating Manual

MP85A process controller

3.3 Supply voltage and control inputs/outputs

Four (MP85A/MP85A-S) or three (MP85ADP/MP85ADP-S) plug-in screw
terminals are available for connecting the power supply and the control inputs
and outputs. Control input/output functionality can be freely assigned with the
PME Assistant (menu: Digital inputs/outputs).
Connecting the power
supply:
Screw terminal 2
(CAN adapter; assignment as for
screw terminal 1)
Screw terminal 3
(control inputs/outputs,
switch test inputs)

CAUTION
Fig. 3.1: Screw terminal assignment
The screw terminals are coded to stop them being fitted into the wrong
socket. The sockets have coding tabs, screw terminals 1 and 2 have coding
pins.
The coding lugs are broken off for screw terminals 3 and 4. The contact
spacing is also different in each case for screw terminals 3 and 4, as well as 5
and 6.
