INNOVEC Controls has released the Inn1 portable calibrator. It is a battery-powered portable current source designed for the calibration or fault finding of 4mA-20mA current loops in source or simulate modes.
Individual push buttons allow the user to select preset current outputs of 0mA, 4mA, 8mA, 12mA, 16mA or 20mA which are able to drive loads up to 300Ω in source mode or operate as a loop current simulator with an external power supply of up to 30V dc.
Electrical connection to the loop is by standard binding post which will accept a 4mm banana plug or the loop wires can be clamped in the binding post itself.
Each selected output current step, low battery and loop over range is identified by LED.
The module’s enclosure measures 97mm x 61mm x 25mm and will fit into a shirt pocket. It comes with a two year warranty.
