Environmental Tolerance and Noise Immunity
The GT2-71MCP operates from -10 to +50 °C without freezing. It handles 35 to 85 % RH without condensation. The PNP output design supports stable switching in industrial panels. The analog output uses a 4 to 20 mA loop for noise-resistant signal transmission. Use shielded cables and a clean 24 VDC supply for best results.
Installation Guide
- Mount the unit on a standard DIN rail inside a control cabinet.
- Connect a 10 to 30 VDC Class 2 power supply.
- Wire the PNP open collector outputs to the PLC or indicator.
- Connect the 4 to 20 mA analog output to a 350 Ω or lower load.
- Attach GT2 series sensor heads and optional communication units.
- Keep signal cables away from high-voltage motor lines.
Commissioning and Maintenance
Set the response time to match your cycle. Use timing, preset, reset, and bank inputs for fast changeover. The digital display shows live values for quick setup. Clean the display and terminals with a dry cloth. Check DIN rail clips and cable strain relief during scheduled maintenance. No internal calibration is required under normal use.
Compatibility Notes
- Works with Keyence GT2 series sensor heads.
- Supports GT2-Pxxx heads with slower response time settings.
- Expands via optional GT2 communication units.
- PNP outputs match common industrial PLC inputs.
- Analog 4 to 20 mA output fits data loggers and panel meters.
