Module type Description
I/O modules Digital input
module
DIM8H High-voltage range, eight optically isolated binary inputs
with common return for two inputs
DIM8L Low-voltage range, eight optically isolated binary inputs
with common return for two inputs
Digital
output
module
DOM4
Four output contacts in each digital output module with
two pairs of potential free contacts with common return
RTD
module
RTD4 Four optically isolated channels supporting RTD sensors
(Pt100, Pt250, Ni100, Ni120 and Ni250) and an mA input
(0...20 mA configurable). Individual channels are non-
isolated from each other.
Analog
output
module
AOM4
Four individually isolated channels of configurable mA
outputs driving 0...20 mA signals
Sensor
input
module
SIM8F
Sensor input module with combined three-phase current
and voltage signals

module
SCM8H
High-voltage range, SCM with five application types
• 4I4O – four input and four output channels
• Three-position switch
• Disconnector
• Circuit breaker
• Earthing switch
SCM8L
Low-voltage range, SCM with five application types
• 4I4O – four input and four output channels
• Three-position switch
• Disconnector
• Circuit breaker
• Earthing switch
The availability and combination of RIO600 modules and channels depend on the
number of power supplies connected.
