| HRIS Alternating Timers Series - Alternating Timer |
| Series Description: The HRPS/HRIS Series combines an electromechanical relay output with microcontroller timing circuitry. It is a factory programmed module available in any 1 of 13 standard functions. It offers 12 to 240V operation in two universal ranges and factory fixed, onboard, or external adjustable time delays with a repeat accuracy of ±0.5%. The output contact rating allows for direct operation of heavy loads, such as compressors, pumps, blower motors, heaters, etc. This series is ideal for OEM applications where cost is a factor. The HRPS has non-isolated SPDT relay contacts, and the HRIS has isolated SPDT relay contacts. Both offer the most popular timer functions in the industry. |
Operation: (Interval)
Upon application of input voltage, the time delay begins. The output (relay or solid state) energizes during the time delay. At the end of time delay the output de-energizes and remains de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and output. |
- Microcontroller based: Repeat Accuracy + / - 0.5% , factory calibration +/- 2%
- Compact design: Allows flexiblility for OEM applications
- 30A, SPDT, Normally Open output contacts: Allows for direct operation of heavy loads
- Encapsulated: Protects against shock, vibration, and humidity
