CT Extension Pack

 Visit the online store page

The eGauge CT Extension Pack can be used to extend CT leads in situations where soldering or butt-splice connections are not possible. CT leads should only be extended using twisted pair wiring and to a maximum recommended distance of 100 feet from the eGauge.  For more details please see:  Extending the Length of CT Leads

The eGauge CT Extension Kit is compatible with all eGauge meter models (eGauge2, EG30xx, EG4xxx)

Hardware included

One extension pack comes with enough connectors to extend 5 CT leads.

Assembly/installation information

Slide the splicing connectors into the mounting carriers by inserting them behind the arrow and gently sliding forward until they click into place.

CT_Extension_Kit-104.jpg

Remove the 2-pin connector from the CT lead and prep the lead to a strip length of 11mm/0.43". Insert one of the stripped wire ends into one end of an inline splicing connector.

CT_Extension_Kit-105.jpg

Lift the lever to insert the CT lead and lower the lever to secure the connection. You should use 1 inline connector per lead wire, using 2 inline connectors and 1 carrier to extend a single CT lead.

CT_Extension_Kit-106.jpg

Strip the ends of the extension wiring to the appropriate length and connect to the other side of the inline splicing connectors in the same way.  Be sure to line up black and white lead wires to the same inline connector.

CT_Extension_Kit-103.jpg

Attach the green 2-pin CT connector to the other end of the CT extension wiring and plug into the eGauge making sure to keep black and white wiring consistent throughout.  Once assembled, give the wires a light pull to be certain that they're securely seated under the closed levers.

Multiple carriers can be connected together if needed using the side-by-side latches on the carriers. The carriers can be mounted or secured as desired.

Step-down transformer

Current manufacturer information: Functional Devices model TR50VA008

Stepdown transformers are intended only to power 120V equipment off higher voltage service. To measure 480V delta systems (no neutral), 600V delta systems (no neutral), or 347/600V Wye, please use the EV1000 High Voltage Sensors.

Step-down transformer (480/277/240/208 to 120V)

208/240/277/480V to 120Vac, dual hub, 50VA UL Listed transformer. Used for monitoring 480V delta services and powering 120V accessories from higher voltage systems.

Transformers provided by eGauge are 50VA (50 watts limit at 1.0 power factor, lower wattage when power factor < 1). They are intended to be used for powering a small amount of equipment provided by eGauge. Attempting to supply loads ~50VA or higher will cause the transformer to trip and require a manual reset.

Power Relay Module (PRM3)

 Visit the online store page
Model: PRM3

Polyphase equipment control danger warning
When controlling single-phase or three-phase loads that have more than one currently-carrying conductors (e.g., hot lines, not neutral or ground), be sure to control the relay inputs for the polyphase load simultaneously using mask controls, or there is risk of having the load operate without all phases which may cause damage to the equipment.

Read the PRM3 Owner's Manual for safety and full control information.

For control: requires eGauge Core or Pro, or a third party controller that supports Modbus RTU or SCPI.

By default, the PRM3 is configured with a 10-second minimum open/close duration to minimize unintentional wear on the relays or rapid load switching. For example, by default when a relay input is opened, it will remain in the open state for at least 10 seconds before a command to close it will be acknowledged. This minimum delay may be reconfigured between 0 seconds and 4 minutes and 15 seconds using Modbus or SCPI commands.

The eGauge Power Relay Module is a versatile device intended to control up to three 240V AC/15 A resistive loads or motors up to 15 FLA (80 LRA). The relays can be opened and closed individually or synchronously, enabling the switching of up to three single-phase loads, one split-phase and one single-phase load, or one three-phase load.

Intended applications include Remote control of air conditioners, heaters, refrigerators, office-automation, and similar equipment.

Assembly/installation information

The Power Relay Module is usually installed near the load (or loads) that it controls. It is permanently connected equipment.

The Power Relay Module is a listed device and must be installed inside a suitable enclosure. The enclosure must be rated according to the environment it is used in. For example, outdoor installations require an outdoor-rated enclosure such as
IPX4/NEMA4.

  1. Connect the source and load hot wires to each applicable relay port (neutral, if applicable, is always left connected directly to the load).
    1. A three-phase load will use all 3 relay inputs.
    2. A single-phase load (2 hots) will use 2 relay inputs.
    3. A split-phase (hot and neutral) will use one relay input.
  2. Connect the USB port and/or RS-485 communication port to the controller or building automation system.
    1. If using using the eGauge meter to control the relay, connect the relay's USB port to an eGauge meter USB port.
    2. If using SCPI control with a third party controller, connect the relay's USB port to the a controller USB port.
    3. If using Modbus control with a third party controller, wire the D+, D-, and Ground pins of the relay's 4-pin plug to the controller's RS485 line. Power is provided via the +5V and Ground pins on the 4-pin plug, or by connecting the relay USB port to another host.
  3. When controlling polyphase loads with multiple relay inputs, open and close the relays simultaneously (such as with masks) to avoid damage to the equipment.

Software Configuration

Be sure to use mask commands for controlling polyphase loads that use multiple PRM3 contacts!

The eGauge PRM3 may be controlled through several different options:
