SEM1700 Signal Conditioner

Brand: Status Instruments

The SEM1700 is a new generation DIN rail mounted universal signal conditioner from Status Instruments.

It has been designed to accept most common process and temperature sensor inputs and provide the user with a programmable current or voltage output signal plus dual relays with a programmable delay function.

Isolation is provided between input, outputs and supply.

All temperature ranges are linear to temperature.

Both input and output loop excitation is provided as well as a fully universal power supply.
