True RMS Current Transmitter - #5021

The model 5021 is a two wire, true RMS, current transmitter that provides a 4/20mA signal proportional to the RMS value of the output of a current transformer.

The circuit is intended to be mounted directly to a current transformer which outputs 0 to 100ma proportional to the current passing through it. 

Additional Features

• Reverse supply voltage protection.
• Zero-cross or Phase-angle signals.
• Selectable Current Range.
• Field-adjustable filter time constant.
• Zero and Span adjustments.
