Key Specifications
Parameter Value / Description
Model UM330-00 (Standard type)
Display Type Large LED display for process variable (PV)
Input Universal input: thermocouple, RTD, DC voltage, etc.; can set input type and ranges via configuration.
Alarms Three alarms standard. Six alarm types available overall; four alarm set-points (one optional). Alarm types include: PV high limit, PV low limit, deenergized on PV high/low limit, fault diagnosis, FAIL output.
Retransmission Output Yes; standard analog output of PV (4-20 mA)
Loop Power Supply Standard 15 V DC loop power supply; optional 24 V DC loop power supply available.
Power Supply for Instrument 100-240 VAC, 50/60 Hz.
Contact Inputs One contact input: can reset maximum/minimum values of the PV. Non-voltage contact or transistor open-collector input.
Contact / Relay Outputs Alarm relay outputs: ratings around 240 VAC, 1 A; 30 V DC, 1 A for alarms 1-3. Alarm 4 (if present) higher rating (e.g. 250 VAC, 3 A) depending on model.
Signal Processing Functions Bias addition (-100.0 to +100.0% of input span), first-order lag (filter) with time constant off or 1-120 seconds; retains & displays max/min PV; reset of max/min.
Alarm Setup Parameters Alarm hysteresis (0.0 to 100% of input span), delay timers (0.00 to 99.59 min:sec); setting ranges for alarm set-points from -100.0 to +100.0% of input span.
Environmental Conditions Ambient operating temperature: 0 to 50 °C (with some restrictions if 24 V loop power); humidity 20-90% RH non-condensing; certain vibration / shock tolerances; storage and transportation extremes larger.
Physical / Mounting Panel cutout: 1/8 DIN; mounting brackets provided; size and depth compatible with panel mounting; need clearances for ventilation, wiring etc.
Weight Approximately 1.46 lbs (≈ 0.66 kg) in standard configuration.
