Suitable for monitoring the status and fault conditions of unattended plants, STM130M timer relays from Ptronik are adjustable from 3-100 minutes.
The relay and memory in these timer relays is engaged if input contacts are closed for a set delay time. The relay releases when the contacts are opened and the memory remains engaged until manually reset.
These relays feature:
- temperature operation range of 0-55ºC
- 240VAC ±10% supply voltage in standard units
- 240VAC 5A output relay contacts; and
- low voltage and low current input contacts.
If this condition ceases before an operator reaches the plant, the memory indicator will remain engaged to flag which STM130M timed out. The operator is then able to manually reset all memories.
