Turck IM34-11EX-I 7506630 Temperature Measuring Amplifier Input For Pt100 Ni100 Resistors 4…20 mA

1. Overview of the Turck IM34-11EX-I 7506630

The Turck IM34-11EX-I 7506630 is a temperature measuring amplifier. It instantly converts microvolt signals from Pt100, Ni100, or thermocouples in hazardous areas into a universal current of 4–20 mA. Its ±0.1% accuracy allows precise measurement of every degree within the 0-1990°C range. Its eight international explosion-proof certifications, including ATEX, IECEx, and UL, ensure rock-solid stability even in Zone 2, eliminating the need for on-site wiring in explosion-proof enclosures.

2. Core Features:

• Order number: 7506630
• Type: Single-channel temperature measuring amplifier (Ex version)
• Power supply: 20…250 V AC (40…70 Hz) or 20…125 V DC, power consumption ≤ 3 W
• Input signal:
– 2-/3-/4-wire Pt100/Ni100 RTDs (IEC 751/DIN 43760)
– Thermocouples B, E, J, K, N, R, S, T (ITS 90/IEC 584)
– Low-level mV signal: -160…+160 mV
• Output signal: 0/4…20 mA (linear, temperature-dependent), load ≤ 600 Ω
• Setting method: Rotary switch, adjustable range from -100…1990 °C (1 K or 10 K steps)
• Accuracy:
– RTD input ±50 mΩ, drift ±3 mΩ/K
– TC input ±15 µV, drift ±3.2 µV/K
– Output current ±5 µA, drift 0.0025 %/K
• Response time: Rise/fall ≤ 1 s
• Intrinsic safety: Ex ia IIC T4 Ga / Ex ia IIIC T135 °C Da (ATEX, IECEx, UL, cFMus, TR CU, INMETRO, CCOE, NEPSI, KOSHA)
• Isolation: Input-output-power supply 2.5 kV AC
• Housing: IP20, plastic PC/ABS, dimensions 104 × 18 × 110 mm, weight 157 g
• Mounting: DIN rail NS35 or panel mount, -25…+70 °C (UL/FM: -25…+60 °C)

All-in-one input: RTD, TC, and mV inputs – no module replacement required.
Explosion-proof direct mounting: Can be installed directly in Zone 2/Div 2 applications, eliminating the need for an additional isolation barrier.
Wire break/short-circuit monitoring: Optional 0 or >22 mA output during a fault condition, facilitating PLC diagnostics.
Wide-range power supply: 20 V–250 V AC/DC, one model covers global power grids.
Cold junction compensation: Optional internal automatic or external Pt100 compensation ensures thermocouple accuracy.
