STWA2AH Electronic current transformer, Measuring Transducer AC 0-20/100 A ... DC 4-20mA

Delivery time on request
- Part number: S225580
AC Electronic current transformer with analog output, 2 measuring ranges, 2-wire execution
The STWA2 AH is a current-transducer for AC currents 0...20/100 A. With the STWA 2 AH the value of a current can be evaluated very economically and space-saving. The output-signal 4...20 mA can be evaluated or displayed with components with analog inputs, e.g. PLCs or ZIEHL digital displays type MINIPAN ®.
Overview of Functions
- current-proportional analog output DC 4...20 mA according to AC-measuring range
- measuring range (20/100 A) can be changed with bridge
- insulated analog output
- supply DC 9-30 V (via 4-20 mA-loop)
- electrical connection via screwless pluggable terminals
- DIN-rail-mount or with screws
- plug-in current transformer (Ø 11 mm)
