Solid-state relay / contactor with load current measurement
PH 9270/003
- Article number: 0064913
- Type: PH9270.91/003/02 AC24-240V AC25A
Product description
The solid-state relay PH 9270 with two thyristors connected in anti-parallel is designed as a zero-voltage switch. When the control voltage is applied, the output of the solid-state relay is activated at the next zero crossing of the sinusoidal mains voltage. After the control voltage is removed, the solid state relay switches off again at the next zero crossing of the load current.
The solid-state relay with its 0 ... 10 V or 4 ... 20 mA analogue output is particularly suitable for heating processes where faults need to be detected as early as possible. It enables continuous monitoring of the load current and offers a wide range of applications thanks to its fast and silent switching, e.g. in injection moulding machines in the plastics and rubber industry, in thermoforming and packaging machines or in the food industry.
