Detects failures in SSR used for heater temperature control and simultaneously outputs alarm signal. This SSR supports the safe design of heater control systems, and contributes to maintenance improvements by the user.
- Main detection items:
SSR short-circuits and SSR open-circuits - Alarm output possible to NPN/PNP-input devices.
- The failure-detection function is built-in and power is supplied from the main circuit power supply making wiring simple.
- Slim design (width: 22.5 mm) incorporating a heat sink.
- In addition to screw mounting, DIN track mounting is also possible.
