The FlexMod Electronic Voltage Sensing Relay & Timer monitors both battery voltage and ignition status, shutting down non-critical loads when the cutoff voltage is reached, or at the set time after the ignition is turned off. It is a timer and voltage sensor in one easy-to-connect unit.
Ideal for use in emergency vehicles, the unit senses both voltage and time after the vehicle engine is turned off. If either the cutoff voltage or time limit is reached, the Voltage Sensing Relay & Timer FlexMod will shut down the auxiliary loads. The dual technology provides double protection.

- Compact unit mounts anywhere on a vehicle and is waterproof, dustproof, and vibration-proof to IP67 standards
- Controls two outputs and monitors voltage and time on both to prevent auxiliary loads from draining the battery and prioritize of load-shedding
- Simultaneous time and voltage sensing preserves starting power even when the battery charge is low, which reduces need for jumpstarts
- 10A rating means it can handle many loads directly or drive a relay or solenoid for higher amperage
- Unit is autoranging - senses 12V or 24V systems.
- Unit can be used with factory-programmed presets or programmed by users
