SM-I/O Plus Termination

Features

All connections from the Solutions Module to the drive are made via the drive connector.
Connections from external equipment to the SM-I/O Plus are made via a 3-way pluggable screw connector for the two relays, and a 12-way pluggable screw connector for the digital and analog I/O.
A total of three SM-IO Plus' can be fitted at any one time.

The SM-I/O Plus increases the I/O capability of the Unidrive SP by adding the following to the existing I/O in the drive. The SM-I/O Plus can be fitted into any one of the three Solutions Module slots provided, with a maximum of three SM-I/O Plus being fitted to a single drive.

24V internal power supply
If the user load exceeds 240mA at 24V, (24V internal power supply), then an external
24V power supply will be required which should be connected to the drive's control
terminals 1 and 2.
The user load comprises of:

• The drives digital outputs plus the SM-I/O Plus digital outputs
  Or

• The drives main encoder supply plus the SM-Universal Encoder Plus encoder
  supply

The maximum output current from the drive's digital output terminals 22, 24, 25 and 26 is 240mA at 24V, exceeding this will result in an ‘O.Ld1' digital output overload trip.
The SM-I/O Plus has a maximum output current of 250mA at 24V across all three digital outputs.
