Electronic Current-Transformer Type STWA1SH
AC Electronic current transformer, fixed switching point
Share:
Part number
Product description
The STWA1SH is used where current flow has to be detected, with the exact value of the current either known from the power consumption of the connected consumer or does not matter for the evaluation.
The STWA1SH has an integrated electronics with transistor-output.
- isolated transistor-output max. DC 40 V / 40 mA
- output van be directly connected to a digital input of a PLC
- integrated diode for reverse voltage protection
- electrical connection via screwless pluggable terminals
- 2- wire, no supply voltage required
- DIN-rail-mount or with screws
- plug-in current transformer (Ø 11 mm)
- max. overload 100 A continuously, 300 A max. 10 s
