The COCIS GMR-32B is a three-phase power supply protection relay commonly used for industrial equipment like central air conditioners, elevator motors, and pumps. It uses micro-control circuits to detect faults and cut power to prevent equipment damage. Key Technical Specifications The GMR-32B is designed for voltage systems up to 500V.
Operating Voltage: Up to 500V AC (Standard models often cover 200–500V). Protection Functions:
Phase Sequence/Reverse: Prevents motor rotation in the wrong direction. Phase Loss: Detects dynamic or static phase failure.
Voltage Monitoring: Over-voltage and under-voltage protection.
Phase Imbalance: Detects asymmetry in the three-phase power. Standards: Complies with IEC60947-1:2007 and IEC61000. Installation & Wiring Guide Installation is typically done on a standard DIN rail.
Input Connection: Connect the three-phase supply lines (L1, L2, L3) to the terminals labeled R/A, S/B, and T/C.
Output Connection: Wire the relay's control output to the contactor coil or motor starter circuit.
Phase Matching: Ensure the phase sequence is correct; the unit will not operate normally or light its indicators if the sequence is reversed.
Initial Test: Once powered, check the status LEDs. A stable indicator usually means correct operation, while specific flashing patterns indicate faults like phase reversal or imbalance. Visual Reference

is a three-phase sequence monitoring relay (also commonly called a phase controller or protector) used to safeguard industrial equipment like motors, compressors, and pumps from power supply faults. It is widely used in central air conditioning units, elevators, and distribution boxes to prevent damage from phase reversal or voltage imbalances. AliExpress Key Technical Specifications
The GMR-32B is designed for high-reliability industrial monitoring with the following typical parameters: Operating Voltage: Commonly rated for
(ranges include 220V to 460V depending on the specific model). Frequency: Compatible with power systems. Contact Capacity: Typically rated at DIN rail (HT35) or screw mounting. Indicators: Features 5 LED indicators to signal status:
Normal, Phase Loss, Reverse Phase, Overvoltage, and Undervoltage Installation & Wiring Guide Follow these steps for a safe installation based on the manual and technical guides Safety First: Ensure all power is disconnected before beginning.
Secure the relay on a standard DIN rail within an enclosed control panel to avoid vibration. Main Circuit Wiring (Input): Connect the three-phase power lines ( L1, L2, L3 ) to the input terminals.
Use insulated copper wire (1.0~2.5mm²). Ensure the wire is inserted fully (8mm depth) to maintain dielectric strength. Control Circuit Wiring (Output):
Wire the relay’s output terminals (typically two normally open/closed pairs) to the contactor coil or motor starter circuit. gmr-32b phase controller manual
This ensures that if a fault is detected, the relay will immediately trip the contactor and cut power to the equipment.
install the GMR-32B on the output side of a variable frequency drive (VFD); it must be installed on the supply side. Troubleshooting with LED Indicators
The front panel provides immediate diagnostics for system health:
The system is in the correct phase sequence and within voltage tolerances. Reverse Phase:
Two phases are swapped. You must swap any two of the L1, L2, or L3 input wires to fix the sequence. Phase Loss / Unbalance:
One phase is missing or there is a significant voltage difference between phases. Over/Undervoltage:
The incoming voltage has exceeded or dropped below the safe threshold (e.g., ±15% for smart models). AliExpress wiring diagram for your motor type or information on where to a replacement unit?
The GMR-32B (often branded under COCIS or Jiefeng) is a three-phase power supply protection relay designed to safeguard industrial equipment like motors, air compressors, and elevators from electrical faults. Key Functions & Protection Features
Phase Sequence/Reverse Protection: Automatically trips if the phase order (L1, L2, L3 or R, S, T) is incorrect, preventing motors from running in reverse.
Phase Loss Protection: Detects both static (before start) and dynamic (during operation) phase breakage.
Voltage Monitoring: Protects against over-voltage and under-voltage conditions beyond set limits.
Voltage Imbalance: Monitors for significant differences between the three phases. Technical Specifications Rated Voltage 380VAC (Standard) or up to 690V depending on model Frequency Contact Capacity 250VAC 6A (AC15) / 30VDC 3A (DC13) Power Consumption Installation 35mm DIN rail mount or screw mounting Operating Temp -10°C to +55°C Installation Guide
Safety First: Disconnect all power and follow lockout/tagout procedures before beginning installation.
Mounting: Secure the relay onto a standard 35mm DIN rail or use the M4 screw holes.
Input Wiring: Connect the incoming three-phase lines to the L1, L2, and L3 (or R, S, T) terminals. The unit is passive and draws power directly from these lines.
Output Wiring: Connect the output control terminals (typically NO/NC/COM) to the coil of your motor contactor or control circuit.
Testing: Restore power. A stable status light indicates correct phase sequence. Simulate a phase error (if safe) to verify the relay trips as expected.
Note: Do not install this unit on the output side of a variable frequency drive (VFD); it must be sampled from the main power supply side. The COCIS GMR-32B is a three-phase power supply
