GE Multilin HE693RTD660 Temperature Monitoring Relay
Manufacturer:General Electric
Product Number:HE693RTD660
Payment Methods:T/T, PayPal, Western Union
Condition:New & In Stock
Warranty:1 Year
Lead Time:1-3 Working Days
Certificate:COO
Courier partners:DHL, UPS, TNT, FedEx and EMS.
Business hours:7*24
Product Description
The HE693RTD660 is a high-precision temperature monitoring relay designed for industrial applications requiring reliable RTD (Resistance Temperature Detector) input and alarm functionality. Part of GE Multilin’s HE series, this relay offers advanced temperature protection and diagnostics for critical machinery, ensuring optimal performance in harsh environments.
The HE693RTD660 monitors temperature via up to 6 RTD inputs (3-wire, 100 Ω platinum/nickel) and triggers alarms or shutdowns when thresholds are exceeded. Its programmable setpoints and hysteresis control prevent false trips in fluctuating conditions. With 110–250 VAC/DC power compatibility and IP54-rated enclosure, this relay is ideal for industries like manufacturing, energy, and water treatment. Key features include Modbus RTU communication and UL 508 certification.
Technical Specifications
| Parameter | Specification |
|---|---|
| Input Voltage | 110–250 VAC/DC (50/60 Hz) |
| RTD Inputs | 6 channels (100 Ω Pt/Ni, 3-wire) |
| Temperature Range | -200°C to +600°C (-328°F to 1112°F) |
| Accuracy | ±0.1% of reading or ±0.5°C (whichever is greater) |
| Response Time | < 100 ms (alarm activation) |
| Outputs | 2 SPDT relays (5 A @ 250 VAC) |
| Communication | Modbus RTU (RS-485) |
| Dimensions | 110 mm (H) × 90 mm (W) × 120 mm (L) |
| Weight | ~0.8 kg (~1.76 lb) |
| Certifications | UL 508, CE, IP54 |
Key Advantages
- High Precision: ±0.1% accuracy ensures precise temperature control in pharmaceutical reactors.
- Multi-Channel Monitoring: Supports up to 6 RTDs, reducing costs vs. single-channel alternatives.
- Flexible Configuration: Customizable alarm delays and reset modes adapt to unique process needs.
- Remote Access: Modbus RTU enables real-time temperature data logging via SCADA systems.
Case Study: A U.S. food processing plant reduced equipment downtime by 25% using the HE693RTD660 to monitor oven temperatures, preventing product spoilage.
Applications & Use Cases
- Industrial Machinery: Protects motors, pumps, and compressors from overheating.
- HVAC Systems: Monitors chiller temperatures in commercial buildings.
- Chemical Processing: Ensures safe operating temperatures in reactors and storage tanks.
Example: A German plastics manufacturer deployed HE693RTD660 on extrusion lines, cutting maintenance costs by $80,000 annually through early fault detection.
Competitor Comparison
- More Input Channels: Supports 6 RTDs vs. 4 in comparable models.
- Faster Response: 100 ms alarm activation vs. 150–200 ms in competitors.
- Cost-Effective: 15% lower cost per channel for multi-point monitoring.
Selection Recommendations
- Voltage Requirements: Choose HE693RTD660 for 110–250 VAC/DC systems; use HE693RTD24 for 24 VDC applications.
- Hazardous Areas: Pair with explosion-proof enclosures (e.g., NEMA 7) for Class I, Division 1 environments.
- Expandability: Integrate with GE’s RX3i PLC for advanced control logic.
Installation & Maintenance Notes
- Mounting: DIN rail or panel-mount with optional enclosure for outdoor use.
- Cabling: Use shielded twisted-pair wires for RTD inputs to minimize interference.
- Calibration: Factory-calibrated; verify accuracy annually using a precision thermometer.
- Troubleshooting: Front-panel LEDs indicate power, communication, and alarm status.
