5.5.3.2 Loop Wiring
Loop wiring is common to all
modules. Refer to diagram below.
Break wiring run to maintain
supervision of the loop.
5.5.3.3 Input Module
22
One supervised input EOL = 27Kohm
5.5.3.4 Input / Output Module
One supervised input EOL = 27Kohm
One supervised output EOL = 27Kohm,
Maximum rating = 30V DC, 2A

Undefined terminal
positions are not
used.
DO NOT use these terminals for the
connection of any wiring.
An EN54-4 PSE shall be used to
provide 24V DC Power for the I/O
and Output modules. Ensure this is
of sufficient rating for the applied
load.
Outputs must be protected against
possible back-emf using a 1N4004
diode (or equivalent) across an
inductive load or varistor if the
voltage is AC.
5.5.3.5 Supervised Output
Module
One supervised output EOL = 27Kohm,
Maximum rating = 30V DC, 2A
5.5.3.6 Relay Output Module

5.5.3.7 Micro Modules
There are four standard types of micro module available. These provide equivalent functions to and have the
same type codes as the standards modules.
Relay Output Module (Single Pole – Form C)
Input / Relay Output Module (Single Pole – Form C)
The modules are provided with a heat-shrink
sleeve for protection.
Flying leads are provided for connection.
Input and output specifications are as per
standard modules.

VMIC120, VMMIC120 and VMDIC120 offer the features of the Input and relay output modules in one device. The input and relay output
wiring is as defined for the individual input and output modules.
