Key Features and Benefits
Expanded I/O Capacity: The adds eight digital inputs and four relay outputs to the base 369 relay. You therefore monitor more field contacts and control additional devices without extra hardware.
Flexible Input Compatibility: Each digital input accepts a wide range of voltages from 24 to 240 VAC or DC. Consequently, you connect directly to various field devices without external converters or signal conditioners.
High-Capacity Output Relays: The four Form C relays switch up to 8 amps for direct control of contactors and solenoids. You eliminate intermediate relays in many applications, simplifying panel wiring and reducing cost.
Isolated Analog Outputs: Two 4-20 mA outputs provide retransmission of motor current, temperature, or other parameters. Therefore, you connect directly to chart recorders, remote displays, or control systems.
Clear Status Indication: Individual LEDs show the current state of each input and output channel. You quickly verify operation and troubleshoot wiring issues without additional test equipment.
Detailed Functional Description
The primary function of the GE involves expanding the I/O capability of the Multilin 369 motor protection relay. Specifically, it plugs into the expansion slot on the 369 base unit and communicates through the internal expansion bus. The module makes additional digital inputs available for monitoring auxiliary contacts, switch positions, or external trip signals. Its four relay outputs provide extra control capacity for annunciation, motor start/stop, or interlocking functions. The two analog outputs continuously transmit selected motor parameters for remote monitoring or trending.
Input Characteristics and Performance
We designed the digital inputs of the 369-HI-R-M-0-2-0-0 for maximum flexibility:
| Parameter | Value |
|---|---|
| Input Voltage Range | 24-125 VDC / 24-240 VAC, 50/60 Hz |
| Input Current | 3-10 mA typical depending on voltage |
| ON Threshold | > 70% of nominal voltage |
| OFF Threshold | < 30% of nominal voltage |
| Response Time | < 10 ms typical |
| Input Type | Optically isolated, polarity insensitive |
You configure each input individually as wet (voltage-sensing) or dry (contact-sensing) via relay software.
