DRA-TCI-2D Thermocouple Input Model
DRA-RTI-2D RTD Input Model
Model DRA-TCI-2D is available for thermocouple types J, K, T, E, R, S or B and provides exceptional temperature linearization by applying eight segment linearization circuitry.
Model DRA-RTD-2D accepts 2 or 3 wire Pt-100 RTDs, alpha = 0.00385. Both models are field rangeable using a set of six internal dip switches for coarse ranging and front accessible zero and span potentiometers for fine adjustment. Test terminals are provided to monitor the transmitter's 4-20 mA output without disturbing the actual process loop. Models DRA-TCI-2D and DRA-RTI-2D include an integral 0.3" high 31Ž2 digit back-lit LCD temperature display.
SPECIFICATIONS
Burnout Protection: upscale
Cold Junction Error: ±0.9°C typical for 0 to 60°C ambient change (±3°C for types R and S)
Accuracy (Including Linearity): ±0.08% of span for type K,
±0.1% to ±0.2% for other thermocouple types
