INSTALINK-CLI 4-20 mA Loop Isolator

Brand: Emphatec

This module interfaces a field transmitter producing 4-20 mA to a PLC or DCS input. Power to the field transmitter is provided by an external power supply. 

The InstaLink-CLI provides up to 2.5 kV of input-output isolation and also features overvoltage transient protection on the input. Unique features of the InstaLink-CLI include the make-before-break connector and adjustable response time. 

The make-before-break connector allows a meter to be inserted into the input loop and removed without causing a momentary interruption of the loop. This makes calibration very easy. A test cable is available. Adjustable response time allows the user to select one of four response times – 1 ms, 35 ms, 350 ms or 400 ms.
Features
  •  Eliminates ground loop caused by differential ground voltages

  •  Make-before-break test jack for temporary connection of a meter

  •  Loop powered (2-Wire) input and output termination for shield on input side

  •  Adjustable response time from 1 to 400 ms

  •  Plug-in jumpers for output loop supply and shield reduces installation time (jumpers included)

  •  Mounts on 32 and 35 mm DIN rails
