Voltage Monitor – V1C

R476.67

The V1C is a precise UNDER / OVER voltage monitoring relay. The unit can be ordered in many AC / DC voltage ranges, making it ideal for many voltage monitoring applications.

 

The set point and hysteresis can be adjusted with separate potentiometers.

 

The unit also incorporates a latch facility to prevent undetected failures.

 

Features:

 

  • Monitoring relay for voltage control
  • Measures separate voltage input
  • Rear DIPswitch selection of UNDER / OVER voltage
  • Rear DIPswitch selection for 10sec start-up delay
  • Potentiometer adjustable voltage limits
  • Potentiometer adjustable hysteresis limits
  • Power supply ON and Relay ON LEOs
  • Latch facility incorporated
  • Output 10A SPDT relay

Description

Function 1: Over Voltage

 

The relay will de-energize if the voltage exceeds the set limit. If the voltage reduces by the percentage hysteresis of the set value the relay will energize.

 

Example: Protection for over voltage of equipment.

 

Function 2: Under Voltage

 

The relay will de-energize if the voltage drops below the set limit. If the voltage Increases by the percentage hysteresis of the set value the relay will energize.

 

Example: Protection for over voltage of equipment.

Pump Sequence Relay – PSR1
Pump Sequence Relay – PSR1

Pump sequence module is designed to optimize the wear on pumps, compressors or generators. The first input energizes the first pump and stores this in non-volatile memory. Subsequent inputs will energize the next output. The number of its outputs correspond to the number of outputs. After power down or no inputs activated and an input is activated, the next in the sequence of outputs is activated. This ensures balanced usesage of the pumps because the same pump is not activated at the beginning of a sequence.

 
Features:
 
  • Three normally open pressure switch inputs (voltage free)
  • Three normally open pump outputs
  • Permanent memory for next pump activated after power off
  • Output 10A SPDT
