The Emphatec InstaLink - CLIx/8 was designed for use with PLC or DCS analog input cards, such as the Controllogix 1756-IF8. Up to 8 transmitters are connected to the inputs and a cable is available for quick connection to the PLC card.

The module provides terminals for cable shields as well as a make-before-break test jack on each input. These allow quick and easy insertion of an ammeter into each input during troubleshooting, commissioning or calibration. 

Transformer coupling means the output is powered from the input - no power suppy is required in the output circuit. It provides fast response time and excellent accuracy. Because power is being coupled across the isolator the voltage drop measured across the input terminals varies according to the output loop impedance. For this reason transformer coupled loop isolators do not have an input impedance specified in ohms.
