About the 239-RTD-AN-H

One key difference between the 239-RTD-AN-H Relay and other relays within this series is that while it is still an analog resistance temperature detector or RTD for short, there is a harsh environmental conformal coating that other relay systems do not have. As already mentioned this unit is analog and therefore has an analog output that can be used in correspondence with automated equipment, a programmable controller, and a chart recorder.

The 239-RTD-AN-H can be used for continuous monitoring and can choose from a few different parameters, which include an Average Phase AMPS, Motor Load, and Thermal Capacity. Each phase has a percentage of a full load. Temperature options underneath the RTD1, RTD2, or RTD3 options are also required. The values that are associated with the 239-RTD-AN-H relay can be accessed digitally through the communication interface. 

When using the 239-RTD-AN-H it is wise to know what the connected motor load is so the motor can be adjusted accordingly to prevent the relay from tripping. The analog can be used with a remote meter, which is sold separately and can be calibrated from zero to one hundred percent of the motor capacity being used. This meter should be situated near the operator and connected to the relay. This meter indicates the amount of memory that has been charged corresponding to the heat buildup of the motor. If during operation the meter is approaching a hundred percent capacity it indicates that the relay is on the verge of being tripped. The meter has a lockout time and will indicate how much charge is left in the memory to show how long the lockout may last.

Frequently Asked Questions about 239-RTD-AN-H

What differentiates the GE Multilin 239 motor protection relay from the motor protection relay with the 239-RTD-AN-H options for the order code?
The difference in the 239-RTD-AN-H order code from the parent motor protection relay is that the H order code signifies the additional featrue of the harsh environment conformal coating. 
What are the analog options for the GE Multilin 239-RTD-AN-H?
The analog options for the GE Multilin motor protection relay with part number 239-RTD-AN-H come in three options: 0-1 mA, 0-20 mA, and 4-20 mA. Output relays for the voltage are either resistive or inductive.
What are some faults that the Multilin 239-RTD-AN-H can protect against? What are typical applications for this motor protection relay?
Typical applications and reasons for installation of this relay are to protect against some common mechanical faults. For example this product can detect a closed discharge valve or loss of suction. This product can also protect against mechanical jam and protect from operator fault by using a thermal memory lockout feature. The GE 239-RTD-AN-H has these and other features making this product an ideal choice for electrical protection of motors.
