Turck MK36-11EXO-LU Relay Module

Turck MK36-11EXO-LU Relay Module (model MK36-11EX0-LU/24VDC, alternate part number 7509520) is a 1‑channel intrinsically safe signal isolator designed to transmit analog process signals between hazardous and non‑hazardous areas in industrial plants. It provides galvanic isolation between input, output, and supply circuits for safe transmission of 0/4‑20 mA or 0/2‑10 V input to a 0/2‑10 V voltage output, powered from 24 VDC with an operating range of 19–29 VDC. The unit is DIN rail mountable and uses terminal block connections, with IP20 protection. It features lineality ≤0.1% of full scale and temperature drift ≤0.02%/K, and test voltage isolation of 2.5 kVrms. Applications include refinery process controls, chemical processing, flow measurement, pressure transmitter circuits, and tank level monitoring, supporting control system expansion and hazardous‑area instrumentation upgrades in oil, gas, chemical, and tank farm environments.
