1.  Overview 
PRM extension module provides additional inputs and outputs for the basic device PR200. The 
module inputs and outputs can be controlled by PR200 as its own I/Os. 
The module is a passive device and cannot be used without connection with the basic device over 
internal bus. 
The module is manufactured in several modifications, differing by the supply voltage. All modifica-
tions are designed in a plastic enclosure for DIN rail mounting. 
Ordering code: 
Supply voltage 
230  - 230 (94…264) V AC 
24  - 24 (19…30) V DC 
I/O 
1 - 8 DI, 8 DO 
Ordering example: 
PRM-230.1 – extension module with 230 VAC supply voltage, 8 230 VAC digital inputs and 8 relay 
outputs. 
►
NOTICE 
Each PRM module is powered independently of the basic device. The basic device and the 
modules may have different supply voltages.
