Description
- Eliminates ground loop caused by differential ground voltages, Make-before-break test jack for temporary connection of a meter, adjustable response time from 1ms to 400ms. Cat. #:330004
This module interfaces a field transmitter producing 4-20mA to a PLC or DCS input. Power to the field transmitter is provided by an external power supply. The InstaLink-CLI provides up to 2.5KV 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 1ms, 35ms, 350ms or 400ms. In applications where fast response is required there are few isolators faster than the InstaLink-CLI. If speed is not critical then the response time can be increased to allow the module to provide some filtering of the incoming signal. The response time can be adjusted quickly and easily via DIP switches.
Another key feature is the plug-in jumpering system for easy distribution of 24Vdc for the module’s output loop (sourcing configuration) and the input (transmitter) cable shield. Jumpers included with each module.
If you are only concerned with ground loops consider Emphatec’s InstaLink-GLF as a possible lower cost solution. If you want economical optical isolation to eliminate ground loops and also to prevent overvoltage transients from reaching your PLC or DCS then the InstaLink-CLI isolator is the solution.
