For voltage and current loops, it accepts 0-1 V, 0-5 V, 1-5 V, or 0-10 V inputs directly, and 4-20 mA signals via external shunt resistors. The device integrates PID control with overshoot suppression and auto-tuning capabilities, ensuring that process stability is maintained even in dynamic industrial environments where variable fluctuation is frequent.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the UT150L provide galvanic isolation between the input signal and the relay output?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the controller maintains electrical isolation between the sensor input stage and the SPDT relay output to protect the internal processing circuitry from common-mode transients on the field side.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 4-20 mA current input be connected directly to the module input terminals?\u003c\/p\u003e\n\u003cp\u003eA: No, the 4-20 mA signal must be converted to a voltage signal using a precision external shunt resistor prior to reaching the UT150L input terminals to ensure proper measurement scaling.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify that the panel cutout dimensions are exactly 45 mm x 45 mm (+0.6\/-0 mm) to ensure the 1\/16 DIN housing fits securely with the provided mounting brackets.\u003c\/li\u003e\n\u003cli\u003eUse shielded, twisted-pair cabling for all analog sensor inputs to prevent electromagnetic interference (EMI) from affecting the ±0.5% accuracy of the measurement.\u003c\/li\u003e\n\u003cli\u003eEnsure the relay output load does not exceed 3 A at 250 VAC; use an interposing contactor for higher-power inductive loads to prevent contact welding.\u003c\/li\u003e\n\u003cli\u003eConnect the sensor ground (if applicable) and instrument common to a single reliable earth point in the cabinet to minimize ground loops and signal noise.\u003c\/li\u003e\n\u003cli\u003eConfirm that the ambient operating temperature remains between -10 and 50 deg C, and provide adequate ventilation within the control panel to prevent overheating of the LED display driver and power supply stages.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":49800592064764,"sku":"UT-150L","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/UT-150L.jpg?v=1783993710","url":"https:\/\/www.electronicplc.com\/es\/products\/yokogawa-ut-150l-limit-controller","provider":"Electronic PLC","version":"1.0","type":"link"}
