Güde Expert Sensor Box 7214-13 Expansion Module for Temperature, Humidity & Air Quality, Modbus RTU RS485, 2 Universal Inputs, Relay Output, Digital Input, 24V AC/DC, IP30, Wall Mount, Pure White

With a potential-free relay output rated at 230 V AC / 3 A, the Güde Expert Sensor Box 7214-13 delivers robust control capabilities for HVAC and building automation. Two universal sensor inputs accept NTC10k, PT1000, Ni1000, and Thermokon FT-D/FT-D-H sensors, enabling flexible environmental monitoring without hardware changes.

Overview

The Expert Sensor Box 7214-13 is an expansion module engineered to extend the capabilities of Thermokon STC-65 series controllers. It provides two universal sensor inputs that accept a wide range of passive sensors, allowing you to connect temperature, humidity, or air quality sensors as required. The device also features one digital input for dry contacts—ideal for door contacts or status signals—and one relay output (normally open) for controlling small loads or alarms. Communication runs over Modbus RTU on an RS485 interface, ensuring reliable data exchange in industrial environments. The compact wall-mount housing in pure white (RAL 9010) blends discreetly into any installation, while the wide power supply range of 24 V AC/DC ±15% simplifies integration.
