This manual covers both models SST7000 and SST7100:

SST7000 Speed Transmitter w/ 4 – 20 mA Output

SST7100 Speed Switch / Transmitter w/ 4 – 20 mA Output & Relay Trip

System Overview

The SST7000 speed transmitter is a DIN rail mountable product designed to convert
rotational speed (RPM) to an industry standard 4 – 20 mA analog output. The SST7100 also
provides 1 relay trip output for over / under speed alarm or shutdown.

Both models will accept a pulsed input from either a 2 or 3-wire speed sensor.

Programming:

The host software allows programming of the SST7000 series via a USB connection to a PC.

Additional Features

• Repeater Output

• 0 – 1 mA local meter output

• 0 – 5 VDC / 0 – 10 VDC selectable proportional output

• Isolated 4 – 20 mA proportional output
