Remote I/O System excom®
I/O Module, Digital, 8-channel
DM80EX
The I/O module DM80Ex is used for the
connection of NAMUR sensors (DIN EN 60
60947-5-6) and actuators. When wire-break
or short-circuit monitoring are activated, mechanical contacts can only be connected with
a corresponding resistor circuitry (WM1, Ident
no. 0912101).
The module features protection class Ex ib IIC
and can be mounted in zone 1 in combination
with excom®. The explosion protection category of inputs/outputs is Ex ia IIC.
■ Input/output module for NAMUR sensors and actuators
The user can furthermore determine whether
an input or an output should be provided at
the connecting point. The following configurations are possible: 8 inputs/0 outputs; 6 inputs/2 outputs up to 0 inputs/8 outputs (GSDfile, Mode 2). This way, optimal adaptation to
the corresponding application environment is
guaranteed.

When connecting the field devices, care has
to be taken that all outputs are on the same
potential.
Input and output mode can be adjusted via
the PROFIBUS-DP master. The following
parameters can be adjusted: switching behaviour, switch-on delay, default value, wirebreak and short circuit monitoring.
