Product Description

The 239-RTD, or resistance temperature detector, is a part originally manufactured by GE. Up to three (3) RTDs must be supplied with a motor.

The other RTDs that can be used with the 239 are one-hundred (100 Ω) ohm nickel, one-hundred and twenty (120 Ω ) ohm nickel, and ten (10 Ω) ohm copper. The 239 requires proper programming so that each RTD input matches up with the installed type. Out of the factory, the 239 default is one-hundred (100Ω) ohm platinum.

The 239 is a relay that senses signals provided by the motor bearings and/or the RTDs that are placed in the stator slots. The 239-RTD has an internally connected ground safety (terminal thirteen). If using the ten ohm copper RTD take care that the lead resistance is as low as possible.

The 239-RTD has a working temperature range -40 to 200 ° C, which equates to -40 to 400 ° F. The trip or alarm range is between 0 to 200 ° C or 0 to 400 ° F.

The dead band for the 239-RTD is two degrees Celsius or four degrees Fahrenheit. The accuracy of the 239-RTD is  ( ± 2 ° C )  or  ( ± 4 ° F).

The Pt or Ni RTD has a lead resistance of twenty-five (25 Ω )ohm max. The Cu RTD has a lead resistance of three (3 Ω ) ohm max with three (3) wire lead resistance compensation.

Frequently Asked Questions about 239-RTD

How does the 239-RTD Multilin relay protect from damage to motors?
The GE Multilin 239-RTD actually sounds an alarm prior to damage from a process malfunction. It can also diagnose and verify correct function. 
Does it matter what voltage is for the motor being protected by the 239-RTD?
No, the voltage does not matter. The 239-RTD system will protect a motor regardless of the specific voltage. 
How many relays are needed?
One 239-RTD relay is needed for each motor, even though motors can be guarded no matter which voltage they are. 
What differentiates the 239-RTD from the 239-RTD-AN and from the 239-RTD-AN-H?
The GE multilin 239-RTD is different from the 239-RTD-AN and from the 239-RTD-AN-H in terms of its composition. The 239-RTD is made to protect three motors, and has a programmable feature. It is also composed of copper, nickel, and platinum.
