Overview

This analog isolator accepts thermocouple (K, E, S, B, J, T, R, N, WRe) and RTD (Pt100, Cu50, Cu100, BA1, BA2, 2/3-wire) inputs. It provides isolated output options: 4‑20mA, 0‑20mA, 0‑5V, 1‑5V, 0‑10V, with load capacity 550Ω for current and ≥1MΩ for voltage. Accuracy varies by type: thermocouples achieve ±0.1% FS or better, RTDs ±0.1% FS, with cold junction compensation ±1°C and 40ppm/°C drift. As a signal conditioner 4‑20mA, it supports single or dual outputs (≤0.7W or ≤1.3W), response time ≤0.5s, and 1500VAC isolation. Powered by 18‑32V DC, it includes DIN‑rail mounting, output ripple <5mVrms, and complies with IEC 61326‑1. Suitable for precise temperature signal conditioning in automation.

Feature

TC Accuracy: K/E/J/N ±0.3°C below 300°C / ±0.1% FS above; S/B/T/R/WRe ±0.5°C below 500°C / ±0.1% FS above.
Cold Junction Compensation: Built-in ±1°C CJC eliminates external probes and extra compensation leads.
Temperature Drift: ultra-low 40ppm/°C drift delivers double the stability of standard 100ppm units across wide ambient temperature swings.
RTD Lead Resistance: 3-wire RTD accepts up to 20Ω per lead, enabling ordinary copper wire runs of up to 100 meters.
Response Time: fast ≤0.5s response ensures real-time temperature control and reliable interlock triggering for critical processes.
Power Consumption: low power draw of 0.7W single or 1.3W dual output at 24V DC, with one input driving two isolated channels.

FAQ

Q1: What's the accuracy difference between thermocouple and RTD inputs? ❯

A: The accuracy is graded separately for each sensor type:

K/E/J/N thermocouple: <300℃ → ±0.3℃; ≥300℃ → ±0.1% F.S.
S/B/T/R/WRe thermocouple: <500℃ → ±0.5℃; ≥500℃ → ±0.1% F.S.
Pt100/Cu50/Cu100/BA1/BA2 RTD: <100℃ → ±0.1℃; ≥100℃ → ±0.1% F.S.

So you get tighter specs where it matters most – low‑temperature RTD measurements deliver 0.1℃ resolution.

Q2: Can I change the input type and range on-site if I order the wrong one? ❯

A: Yes, the MIK-603S is user-programmable. Input type and range can be configured via PC software (no factory return needed). This saves you from having to return the unit if project specs change mid‑stream, or if you accidentally specify the wrong configuration. Contact our support team for the software tool.

Q3: What's the power consumption? Can I pack multiple units on one DIN rail? ❯

A: Very low power draw – single output ≤0.7W, dual output ≤1.3W at 24V DC. You can mount multiple units side‑by‑side on a 35mm DIN rail without any overheating concerns – heat dissipation is minimal.

signal isolator temperature input is a solid choice

I used this module for converting temperature signals from a thermocouple into a standard output for the control system. The signal isolator temperature input was easy to configure and the readings stayed stable during operation. The wiring layout is clear, although checking the sensor type settings before startup is important. It has been a reliable part of the temperature monitoring setup.
