GE SR469-P5-LO-A20-T Relay Protector Module

The SR469-P5-LO-A20-T has a 5 amp current transformer secondary coil mounted on the base unit.

It is a low control power unit rated for 24-60 volts DC or 20-48 volts AC @ 48-62 Hz.

Although the unit has an optional Ethernet port, it does not include the optional DeviceNet or enhanced front panel.

Product Description

The SR469-P5-LO-A20-T is an SR469 multi-wire relay designed to provide comprehensive protection for medium to large motors. The unit offers many management features.

The SR469-P5-LO-A20-T has a 5 amp current transformer secondary coil mounted on the base unit.

It is a low control power unit rated for 24-60 volts DC or 20-48 volts AC @ 48-62 Hz.

Although the unit has an optional Ethernet port, it does not include the optional DeviceNet or enhanced front panel.

In addition, it is not designed for harsh environments as it does not include a chemically conformal coating.

The SR469-P5-LO-A20-T includes an optional Ethernet 10BaseT Ethernet port.

With this additional port, users can connect their 469 units to 10 Mbps Ethernet.

This port brings the number of ports in the unit to four, including the three standard serial ports that are always displayed in the SR469 relay.

All SR469 relays have two RS485 ports on the real panel. In addition, there is an RS232 port on the bottom of the front panel.

This port provides quick access for troubleshooting and programming.The SR469-P5-LO-A20-T supports ModBus RTU and ModBus RTU via TCP/IP.

The GE Multilin manual will provide the user with additional information on installation, safety and proper operation.

Original documentation such as manuals and user guides should be read and understood before opening the box; this will ensure that you are aware of all possible hazards and ensure your safety.

Frequently Asked Questions about the SR469-P5-LO-A20-T

What are the standard features of the SR469-P5-LO-A20-T General Electric Motor Management Relay?

All 469 Motor Management Relay features are standard. Although the analogue output range, phase current transformer secondary and control power must be specified prior to purchase, the

to ensure that the correct standard features are purchased for the relay. Some features are programmable, such as the 469 relay's differential current transformer input with a 1A or 5A secondary current transformer.

Unfortunately (with the exception of relay service), the outputs of the relay are always unprotected against faults.

SR469-P5-LO-A20-T In what environment should I store my GE relay so that it will not be damaged?

Storage of the GE Motor Management Relay SR469-P5-LO-A20-T relay is very important for this unit.

Ambient storage temperatures of -40 degrees Celsius to +80 degrees Celsius, non-condensing humidity up to 90%, and altitudes up to 2000 metres should be suitable for this ge motor.

Any temperature below -20 degrees Celsius may damage the LCD. With long-term storage, the same environmental conditions still apply, the

Store the relay in a non-corrosive environment without direct sunlight, i.e. in a dry environment.

With proper storage, the relay will avoid premature component failure due to moisture or potentially corrosive gases.

These specific precautions will help this relay not be exposed to corrosive or high humidity environments and prevent degradation of electrical components, regardless of the use of the relay.

The SR469-P5-LO-A20-T offers protection features such as overcurrent protection, frequency protection, and ground fault protection.

These features help extend system life and reduce system downtime.
