Yokogawa Limit Controller UT150-RN/AL
General
The UT150-RN/AL is an FM approved limit controller that can be configured either as a high limit or as a low limit controller by a user. The UT150-RN/AL features universal input, two alarm outputs, retransmission output, a timer to count the total time the setpoint is exceeded, and a register to retain the maximum temperature reached. The RS485 communication interface is available optionally.

Hardware Specifications
Measured Value (PV) Input
• Input: 1 point
• Input type: Universal; can be selected by software • Input accuracy (at 23 2C ambient temperature) • Thermocouple: 2C1digit However, • 4C for thermocouple input –200 to –100C • 3C for thermocouple input –100 to 0C • 5C for type R and S (9C for 0 to 500C) • 9C for type B (accuracy is not guaranteed for 0 to 400C) • RTD: 1C1digit • Voltage (mV, V): 0.3%1digit • Sampling period for measured value input: 500ms • Burnout detection: Functions for thermocouple or RTD input (burnout upscale only; cannot be switched off) • Input resistance: 1M or greater for thermocouple or DC mV input. Approx. 1M for DC V input • Maximum allowable signal source resistance : 250 for thermocouple or DC mV input 2k for DC V input • Maximum allowable wiring resistance for RTD input: 10/wire (The resistance values of three wires must be the same.) • Allowable input voltage: 10V DC for thermocouple or DC mV input 20V DC for DC V input • Noise rejection ratio: Normal mode noise: Min. 40dB (50/60Hz) Common mode noise: Min. 120dB (Min. 90dB for DC V input) • Error of reference junction compensation: 1.5C (at 15-35C) 2.0C (at 0-50C) The reference junction compensation cannot be switched off. • Applicable standards: Thermocouple and resistance temperature detector JIS/IEC/DIN (ITS90) •Response time: 2 second or less, 63% (10 - 90%) (The time required for transmission output to reach 63% of the maximum excursion when PV abruptly changes from 10% to 90%)
• Output: 1 point • Output type: Relay contact output Contact capacity: 3A at 240V AC or 3A at 30V DC (with resistance load) Note: The control output relay cannot be replaced by users.
