The document introduces an intelligent transmitter that supports 4-20mA and HART signal output, and has an emergency stop system and multiple size options.
This manual describes Moore Industries' HART signal isolators, which protect 2‑wire (HIX) and 4‑wire (HIT) loops with up to 1500 Vrms isolation. The devices safeguard I/O cards from surges, pulses, and transients, allowing maintenance without breaking the loop.
Technical data such as isolation voltage, input impedance, load capacity, temperature range, and power‑supply options are listed, along with wiring diagrams and selection formats for various installation scenarios. This manual is written in Chinese.
| Isolation voltage | 1500 Vrms |
|---|---|
| Input impedance | 2308 Ω |
| Output current limit | 25 mA (typical) or 30 mA |
| Accuracy | ±0.1 % of span |
| Operating temperature | -20 °C to +70 °C |
| Load capacity (4‑20 mA output) | 12 000 Ω |
| Relative humidity range | 0 %–95 % |
The isolator provides up to 1500 Vrms isolation capability.
It operates from –20 °C to +70 °C.
The output can drive a load up to 12 000 Ω.
