The RS-1112 is a single‑channel isolated current/voltage transmitter with multiple input ranges, several output options, 3000 VDC isolation and high accuracy.
The RS-1112 transmitter converts AC/DC input signals to standardized isolated output signals for power, process control, instrumentation and medical equipment. It supports input current ranges of 0‑1 mA, 0‑10 mA, 0‑20 mA and 4‑20 mA, and offers output options of 4‑20 mA, 0‑20 mA, 0‑5 VDC, 1‑5 VDC and 0‑10 VDC.
Key electrical specifications include 3000 VDC isolation between input and output, accuracy of ≤0.2 %, power supply options of DC 5 V, 12 V or 24 V, operating temperature from –25 °C to +70 °C and humidity 10 %–90 %. The manual provides wiring diagrams, installation steps and calibration procedures. This manual is written in Chinese.
