The 2V67-S Series relay is a three pole voltage monitoring relay with four stages of adjustable voltage pick up & drop out points. Each voltage set point can be set for under or overvoltage operation & has an independent time delay driving an output relay. An undervoltage lockout is used to disable the four voltage outputs when the voltage falls below a preset level. A single status input is used to enable the four voltage sensing stages. The 2V67-S relay is built on the Micro MATRIX-S digital platform.

The standard Micro MATRIX human machine interface (HMI) is combined with fully solid state voltage sensing & measuring circuitry to provide high accuracy, simple set up & flexible operation. Self-monitoring is carried out by hardware & software watchdogs. A CPU software watchdog records abnormal events & performs automatic High speed, high contact rating output relays are employed. A USB programming port is provided for ease of establishing relay settings using a PC.

Changes introduced on the 2V67-S

  • Case length reduced by 18mm to suit 4M56-S case;
  • LED backlighting to reduce EMC emissions – contrast adjustment no longer required;
  • Front panel USB programming port to increase data transfer speed and improve compatibility with notebook PC’s;
  • Network communications port is now optional to maintain low cost of base model;
  • Network communication port maintained the optically isolated RS485 serial port but the RS232 configuration option has been deleted;
  • New current and voltage channels to improve measurement stability;
  • New status input option covering 18-275V AC and 300V DC range;
  • Updated switchmode power supply to reduce EMC emissions and improve transient overload protection;
  • Surface mount production technology to allow increased component density for additional functionality now and in the future.

What has not changed from the 2V67

  • I/O and basic functionality has been maintained;
  • Basic menu structure and operation has been maintained;
  • Electrical terminal mapping has not changed allowing existing wiring diagrams to be maintained;
  • Compatibility with existing application software back to version 0500 maintained;
  • Compatibility with existing uMATRIXwin programming software maintained;
  • Modbus RTU network communication protocol maintained Case size 4 has been maintained although the length has been reduced.
  • Made in Australia


The compatibility of a specific software application version with a hardware Type Number can be verified from the Compatibility.pdf document.

Use the “Save File As” command to download the required ZIP file which contains four items:

.umx software file
.ump sample parameters setting file
.pdf functional description
.pdf Modbus allocation tables for network communications port

The last 4 digits of each .zip file is the software version number which can be checked against the issue level of a relay’s software by accessing the DIAGNOSTICS page from the front panel. This is done by pressing the DATA and SET buttons simultaneously, moving the curser over “VERSION” and pushing SELECT. To load a .umx or .ump file you need to connect to the relays RS232 port using a PC with the uMATRIXwin software.
