Although the device is rated up to +60 degC, dense installations with continuous 24V DC supply can lead to localized heat build-up. It is recommended to maintain a 5 mm ventilation gap between adjacent modules if the ambient cabinet temperature regularly exceeds 50 degC. Additionally, ensure the loop resistance of the passive output configuration does not exceed the maximum load limits specified for your DCS analog input card.\n\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  For thermocouple inputs, always ensure that the cold junction compensation (CJC) is correctly configured in the DTM software.
