2 Introduction
2.1 Features
The SM-I/O 24V Protected is designed as an over voltage protected I/O Solution
Module.
The Solutions Module is able to withstand a +48V input voltage being applied to the
+24V Digital I/O terminals.
The SM-I/O 24V Protected can be used on the following products:
•
Unidrive SP
• Commander SK
• Commander GP20
The SM-I/O 24V Protected increases the I/O capability of the drive by adding the
following to the existing I/O:
•
2 x Analogue current outputs
• 4 x Digital inputs/outputs*
• 3 x Digital inputs
• 2 x Relay (30Vdc contact rating)**
All connections from the Solutions Module to the drive are made via the drive connector.
Connections from external equipment to the relay, digital I/O and analogue outputs are
made via a 17-way pluggable screw connector.
On the Unidrive SP a total of three SM-I/O 24V Protected modules can be fitted at any
one time. On the Commander SK only one can be fitted, on the Commander GP20 two
can be fitted.
*Only three digital outputs are available with Commander SK.
**1 relay on Commander SK
