Products specifications
Brand ZIEHL
Country of origin Germany
Rated supply voltage AC/DC 24-240 V
Ambient temperature range -20...+55 °C
Current output 40 mA
Voltage output DC 40 V
Applied standards UL/CSA

The STWA1S has an integrated electronic with transistor-output. The switching point is 2 A. Above app. 2 A the output transistor is switched on (LOW), below app. 1.5 A it is off (HIGH). The conductor is simply pushed through the transformer.Multiple loops reduce the switching point correspondingly, for instance to 0.5 A with four loops. A supply voltage is not required.

Application

The STWA1S is used where current flow is 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.
For simultaneous evaluation of the current flow in several conductors the STWA1S device can be connected in series (AND circuit, pay attention to the voltage drop) or in parallel (OR circuit, pay attention to the leak current).

  • isolated transistor-output max. DC 40 V/40 mA
  • output can be directly connected to the digital input of a PLC
  • integrated diode for reverse voltage protection
  • 2-wire-connection, 1 m
  • no supply voltage required
  • transformer and electronic unit enapsulated in a climate-proof housing
  • plug-in current transformer (Ø 11 mm)
  • max. overload 100 A continously, 300 A / 10 s
