- The STWA 1 FH is a current-transducer for AC current. With the STWA 1 FH the value of a current can be evaluated very economically and space-saving. The isolated (to signal and supply-voltage) frequency-output can be connected directly to a digital input of a PLC.
- current-proportional analog frequency-output 0,5...20 Hz = 0...20 A
- output max. DC 30 V / 30 mA, insulated with optocoupler
- direct connection to PLC possible
- supply-voltage DC 10...30 V
- integrated diode for reverse voltage protection
- electrical connection via screwless pluggable terminals
- DIN-rail-mount or with screws
- plug-in current transformer (Ø 11 mm)
- option: other current- or frequency-ranges
