Description
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
parameter
• 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
parameter
• 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
output.
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.
Relays
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
Compatible with Unidrive M200/M201/M300/M400/M600/M700/M701/M702
