- Over Temperature detection
- Used in conjunction with PTC thermistors to DIN 44081
- Built-in “Test” and “Reset” buttons
- Latch facility
- SPDT Relay output
- 45mm wide, DIN Rail mount
The product is used in conjunction with an external PTC thermistor (up to 6 max.) that are typically embedded in motors. It will monitor the resistance of the thermistor(s) and if this increases above the fixed set-point (due to an increase in measured temperature), the relay will de-energise. The resistance must decrease below the “release” set-point before the relay re-energises again and if the latch feature is enabled, the relay will only re-energise once the “Reset” button is pressed.
