## **Description** 

## **Inputs** 

Standard ranges are shown below - contact  Sales for others. 

Full 3 port isolation is standard as is an isolated transmitter supply which can be used to power any standard 2-wire 4-20mA transmitter. 

The input type and range can be user selected using simple DIL switches inside the unit. All RTD and thermocouple inputs can be fully linearised. Non-interactive zero and span controls make adjustment of the unit, quick and simple. 

Other features include optional inversion of the input signal, on either one or both of the outputs. 

The unit is supplied with two power supply options either wide ranging ac or dc. The ac version operates from any supply from 90 to 264VAC and the dc version operates from 18 - 32VAC and 16 - 36VDC. 

For specials such as custom linearisation etc please contact the sales office.
