Unidrive M’s extended I/O interface module increases the number

of I/O points on a drive. All connections from the option module

to the drive are made via the drive connector. Connections from

external equipment to the SI-I/O are made via a 3-way pluggable

screw connector for the two relays and an 11-way pluggable screw

connector for the digital and analog I/O.

Features include:

4 x Digital inputs/outputs

3 x Analog inputs (default) / Digital inputs

1 x Analog output (default)* / Digital input

2 x Relays

Digital I/O

By default, the SI-I/O Module is set up for four programmable

digital inputs/outputs. By configuring the analog I/O as

digital inputs, it is possible for the SI-I/O module to have four

programmable inputs/outputs and also four digital inputs.

The functionality of these terminals is as follows:

The logic sense selected can be positive (default) or negative

The logic state of each input is monitored by a read-only


The logic state can be inverted

The digital input can be programmed to any suitable

destination bit parameter

The digital output can be sourced from any suitable bit


The outputs can operate either as a push-pull or an open

collector output

The SI-I/O has a maximum output current of 250 mA at 24 V

across all four digital outputs.

Analog I/O

By default, the SI-I/O is set-up for three single-ended analog

inputs and one analog output or one high resolution* differential

analog input*, one single-ended analog input and one analog


Analog inputs 1 and 2 can only be configured as ±10 Vdc voltage

inputs or digital inputs. When both are configured as analog

voltage inputs, they can be used as a single high resolution

differential analog input.

Analog input 3 can operate in voltage mode (±10 Vdc), current

mode (0 to 20 mA) or as a digital input.

Analog output 1* can operate in voltage mode (±10 Vdc),

current mode (0 to 20 mA) or as a digital input.


The two relays can be used to convey the logic state of any

suitable parameter to external equipment. The logic state is

processed as follows:

A suitable source parameter is assigned to each relay

The logic state can be inverted

The state of the relay is monitored by a parameter
