SM-I/O 120V - Interface module - CONTROL TECHNIQUES

Features

The SM-I/O 120V solutions module can be used on the following products:

• Unidrive SP

• SK Commander

All connections between the Solutions Module and the drive are made through the drive connector.

Connections from external equipment to the SM-I/O 120V are made via a pluggable screw connector.

The 120V SM-I/O increases the I/O capability of the Unidrive SP and Commander SK.

Additional I/O consists of:

• Six digital inputs (120Vac)

• Two relay outputs (120Vav 2A resistive)

The input terminals are organized into three groups of three. Each group serves two inputs with the first two terminals as inputs and the third terminal as the common neutral for the group. Groups are isolated from each other, allowing inputs from up to three different voltage sources or branch circuits regardless of phase. Both inputs in a group must be powered by a single-phase circuit. Each common neutral must be referenced to ground at its source (see Figure 3-1). All I/O of the SM-I/O 120V is user-programmable for function and signal processing.

The SM-I/O 120V can be identified by:

1. The label located under the Solutions module.

2. The color code on the front of the Solutions Module. SM-I/O 120V being olive.

Date code format

The date code is divided into two sections: a letter followed by a number. (see Figure 3- 3 SM-I/O 120V Label on page 9) The letter indicates the year and the number indicates the week number (within the year) the Solutions Module was built. The letters go in alphabetical order, starting with A in 1990 (B in 1991, C in 1992 etc.).

Example: A date code of L35 would correspond to week 35 of the year 2002.
