Page 4 SPECIFICATIONS Typical @ 25 C and rated supply voltage unless otherwise specified. INPUTS: • Input types: J,K,T,E,R,S,B t/c, RTD, Voltage, Millivolt, Current & thermistor • Cold junction compensation error: +/- 0.5C max (10C to 40C) • Open thermocouple indication: ‘OPEN TC’ displayed OPTI...

Page 5 - DESCRIPTION

Page 5 DESCRIPTION Housed in a wall-mount, water-tight plastic enclosure, the DPS3301 Series is a powerful temperature monitor/indicator. It accepts a single Thermocouple, RTD or Thermistor sensor input and then displays the temperature in either degrees C or F. In addition, it also monitors a numbe...
