Product Introduction

The 369-HI-0-M-0-0-E is a motor management relay manufactured by GE Multilin. Control power is 50-300 VDC / 40-265 VAC. There are no optional RTD inputs on this relay. This unit includes an optional metering package. There are no optional fiber optic ports. This relay provides protection and monitoring for three-phase motors and their associated systems. The 369 can "learn" individual motor parameters and adapt to individual applications. To improve the protection capabilities of the relay, the user can adjust motor inrush current, cool down rate and/or acceleration time. If you have any questions about this motor management relay or related series or manufacturers, please contact AX Control.

The Setpoint keys allow the user to navigate through the programmable parameter headers. The Actual Value keys allow the user to navigate through the measured parameter headers. The Page Up and Down keys can be used to scroll through the headers of the Actual Values ​​and Setpoints. The Line Up and Down keys can be used to scroll through the subheadings. The Value Up and Down keys allow the user to scroll through the variables in the Setpoint Programming mode. The Reset key allows the user to reset a tripped or latched alarm. The Enter key allows entry into a subgroup or storage of a changed Setpoint value. The Clear key exits a subgroup or returns a changed setpoint to its original value. The Help key can be pressed at any time for context-sensitive help messages.

You should always ensure that the 369-HI-0-M-0-0-E is properly grounded. You must connect the safety ground and filter ground (terminals 126 and 123, respectively) to the main ground bus to properly ground the device.

Frequently Asked Questions About the 369-HI-0-M-0-0-E
What are the control power specifications for the 369-LO-0-MFE-0-E Motor Management Relay?
The 369-LO-0-MFE-0-E has a low (LO) control power specification. This 369 Multilin Motor Management Relay has a VDC range of 20-60 and a VAC control power range of 20 to 48. This low specification is compared to the high (HI) option (50-300 VDC and 60 to 265 VAC control power).
What additional features does the 369-LO-0-MFE-0-E Multilin General Electric Digital Relay have?

Additional Features of the 369-LO-0-MFE-0-E Includes an optional metering package. This package provides three additional configurable analog outputs in addition to the single analog output of the base unit. This package also provides the unit with inputs for power and voltage components, capable of measuring various specifications such as V, kW, etc. The 369-
LO -0-MFE-0-E also includes an optional fiber optic port denoted by the (F) option. This fiber optic data link is suitable for harsher environments or RRTD connections. The fiber sizes are 50/125, 62.5/125, 100/140, and 200 microns. The type of LED emitter is an 820 nm LED with multimode characteristics.

What is the purpose of the optional fiber optic port of the 369-LO-0-MFE-0-E?

The purpose of the fiber optic port (option F) of the 369-LO-0-MFE-0-E is to allow remote module RTD to be connected to the motor management relay.

High intelligence of field equipment

Traditional DCS uses a relatively centralized control station, which consists of a CPU unit and input/output units. The fieldbus control system distributes the control station functions of the DCS to the field control equipment, and the basic functions of automatic control such as data acquisition and compensation, PID operation and control, equipment self-checking and self-diagnosis can be realized only by fieldbus equipment. The operator of the system can remotely monitor in the control room, set or adjust the operating parameters of the field equipment, and locate and diagnose faults with the help of the self-diagnosis function of the field equipment.

High adaptability to the environment

The fieldbus is designed for industrial sites. It can transmit data using twisted pair, coaxial cable, optical cable, power line and wireless methods, and has strong anti-interference ability. The commonly used data transmission line is a cheap twisted pair, which allows the field equipment to use the data communication line for power supply, and can also meet the intrinsic safety and explosion-proof requirements.

In order to improve the processing capacity of PLC, PLC is required to have better response speed and larger storage capacity. At present, the scanning speed of some PLCs can reach about 0.1ms/k steps. The scanning speed of PLC has become a very important performance indicator. In terms of storage capacity, some PLCs can reach tens of megabytes. In order to expand the storage capacity, some companies have used bubble memory or hard disk. Develop in the direction of super large and super small At present, there are many small and medium-sized PLCs. In order to adapt to the various needs of the market, PLCs will develop in the direction of multiple varieties in the future, especially in the direction of super large and super small. There are now super large PLCs with 14336 I/O points, which use 32-bit microprocessors, multiple CPUs working in parallel and large-capacity memory, and have strong functions. Small PLCs have developed from an overall structure to a small modular structure, making the configuration more flexible. In order to meet market needs, various simple and economical ultra-small micro PLCs have been developed. The number of I/O points of the small configuration is 8 to 16 points to meet the needs of single machines and small automatic control, such as Mitsubishi's α series PLC. PLC vigorously develops intelligent modules and strengthens networking communication capabilities. In order to meet the requirements of various automatic control systems, many functional modules have been continuously developed in recent years, such as high-speed counting modules, temperature control modules, remote I/O modules, communication and human-machine interface modules. These intelligent I/O modules with CPU and memory not only expand the functions of PLC, but also are flexible and convenient to use, expanding the scope of PLC application. Strengthening the ability of PLC networking communication is the trend of PLC technology advancement. There are two types of PLC networking communication: one is networking communication between PLCs, and each PLC manufacturer has its own proprietary networking means; the other is networking communication between PLCs and computers. Generally, PLCs have communication modules to communicate with computers. In order to enhance the networking communication capabilities, PLC manufacturers are also negotiating to develop universal communication standards to form a larger network system. PLC has become an indispensable and important part of the distributed control system (DCS).
