    Overview

    This signal conditioner 4‑20mA accepts RTD (Pt100, Cu50, Cu100), thermocouple (K, E, S, B, J, T, R, N, WRe), potentiometer (0‑20kΩ), and mV (-120~120mV) inputs. It outputs 4‑20mA, 0‑10V, etc., with load 550Ω for current or ≥1MΩ for voltage. As a 4‑20mA signal conditioner, it offers single/dual outputs (≤1W or ≤1.4W), ≤500ms response, 50ppm/℃ drift, and 1500Vrms isolation. Powered by DC 20‑35V, DIN rail mount, 130g, IEC 61326‑1 compliant. Ideal for temperature, resistance, and millivolt signal conditioning.

    Features

    • Universal Input: accepts TC (K, E, S, B, J, T, R, N, WRe), RTD (Pt100, Cu50, Cu100, custom Pt50~Pt1000), potentiometer, and mV signals. No module swapping needed.
    • Flexible Output: one input drives single or dual outputs; adapts to any system without hardware changes.
    • Low power consumption: ≤1W (single-channel), ≤1.4W (dual-channel), minimizing heat in dense cabinets.
    • Fast Response: 500ms real-time processing, suitable for interlock loops and critical control.
    • Robust Isolation: 1500Vrms I/O/power isolation with 50ppm drift, ensuring stable, long-term accuracy.

    FAQ
     ❯

    A: Yes, it accepts TC, RTD, potentiometer, and mV signals all in the same device.

    ❯

    A: The input type and range are factory‑set at order. If you need to modify it on‑site, you'll need to connect the unit to a PC with our configuration software (contact our support team for the tool). For most users, we recommend specifying your exact range at purchase to avoid extra steps.

    ❯

    A: Absolutely. The MIK-1003s is available in both single‑output and dual‑output versions. One input can drive two separate outputs simultaneously – for example, send 4‑20mA to your PLC and 0‑10V to a local display, all from one sensor.

    signal isolator thermocouple rtd is easy to use
    Bought this for a temperature control upgrade and it fit into the setup without much trouble. The signal isolator thermocouple rtd works well with the sensors already in use and the wiring is pretty straightforward. I had to double-check the input settings before starting, but everything ran normally afterward. A simple device that solved the signal conversion issue.
