(Split) temperature transmitter head
Product details
Product Overview：
The WH-Y203 communication type intelligent temperature transmission board adopts LCD display and RS485 communication or 4-40MA (HART protocol) and alarm output integrated board. Through a highly integrated circuit with a microprocessor as the core, it reliably realizes the acquisition and processing of thermal resistance and thermocouple signals as well as RS485 output, fully digital debugging and calibration. Specially suitable for the production and manufacturing of RS485 communication type temperature transmitters.
Features:
- DC24V power supply, RS485 interface;
- Standard MODBUS RTU communication protocol;
- The division number, range, zero point, etc. can be modified through a computer or panel
- Supports four and a half digit LCD display (with backlight);
- Four types of thermal resistors: Pt100, Cu50, Cu100, and Pt1000 (specified in the order);
- K. Eight types of thermocouples: S, R, B, N, E, J, T;
- Thermal resistance three wire measurement, automatically eliminating lead resistance;
- Automatic compensation of thermocouple cold end;
- Fault prompts and output processing for thermal resistance and thermocouple disconnection;
- Support three key parameter settings, calibration, and debugging;
- Independent setting of temperature transmission output range;
- Unique output reversal function;
- High integration, anti-interference design, and software and hardware watchdog
