The Theta 20A AC TRMS Current Transducer is a single-phase din rail mount AC current transducer with high-contrast backlit digital display. This transducer converts the AC measured variable into a proportional analogue DC output. AC input options can be programmed for 1A or 5A CT secondary inputs from standard current transformers with a primary rating from 1A to 9999A. Programmable DC outputs include 0…20mA, 4…20mA or 0…10V.

Programming can either be carried out via the two push button keys on the front display panel, via the front programming port with programming adaptor & PC software or via the optional RS485: Modbus/RTU communication. The transducer is offered with a standard wide power supply of 60-300V AC/DC.

The isolation system meets the requirements of EN61010-1 and for extra safety the transducers case is made from flame retardant self-extinguishing, non-dripping, halogen free polycarbonate with a UL-94 V0 rating.
