TP02-1110-2 PT100 Temperature Transmitter (DIN Rail) is a DIN-rail temperature transmitter designed to convert a 3-wire PT100 input into a stable 4-20 mA signal for PLC, BMS and process control loops. It is loop-powered from 10-30 V DC and scaled for -50 to 0 °C.
🔧 Technical Highlights:
- Input: PT100 Ω RTD (3-wire); sensor current < 0.8 mA; cable resistance ≤ 50 Ω (3 wires with the same resistance).
- Output: 4-20 mA, 2-wire loop; accuracy ± 0.1% of F.S.; response time < 250 ms.
- Power supply: 10-30 V DC (2-wire loop power).
- Load resistance: ≤ (supply voltage - 8 V) / 0.02 A Ω; load resistance stability ±0.05% / 100 Ω.
- Zero/Span adjustment: ±10% zero trim and ±10% span trim.
- Protection: PT100 disconnection output > 23 mA; PT100 short circuit output < 3 mA; output polarity protection.
- Connections (10-30 V DC loop version): PT100 A to terminal 5, PT100 B to terminal 7 and PT100 b to terminal 8. Connect loop/supply + to terminal 1 or 3 and loop/supply - to terminal 2 or 4 (1 & 3 are common, 2 & 4 are common).
- Environment: -20 to +60 °C; 0-95% RH (non-cond.); housing IP30, terminals IP10; ABS housing.
✅ Benefits:
- Provides a standard 4-20 mA signal for long cable runs and noisy industrial environments
- Loop-powered wiring reduces panel power supply requirements
- Fast response supports tighter temperature control and better monitoring
- Clear fault behaviour for open/short sensor conditions
- DIN-rail mounting for compact panels and fast installation
🚀 Applications:
- HVAC heating, ventilation and cooling systems
- Water, power and utility temperature monitoring
- Food, pharmaceutical and environmental process temperature measurement
- Remote PT100 signal transmission to PLC and SCADA systems
TP02 provides dependable PT100 to 4-20 mA conversion for accurate temperature monitoring on DIN rail installations.
FAQs
- Q: What are the terminals for the 10-30 V DC loop-powered TP02?
A: Connect PT100 A to terminal 5, PT100 B to terminal 7 and PT100 b to terminal 8. Connect loop/supply + to terminal 1 or 3 and loop/supply - to terminal 2 or 4 (1 & 3 common, 2 & 4 common).
- Q: Does the TP02 series support a 90-260 V AC supply and what are the terminals?
A: Yes. The 90-260 V AC version uses terminals 1 and 3 for AC power, terminals 8 (+) and 7 (-) for the 4-20 mA output, and terminals 12 (A), 11 (B) and 10 (b) for the PT100 input.
