Specifications
Input:
Type E, J, K, or T thermocouples.
Output:
4 to 20 mA DC over specified range.
Accuracy:
TT190: +/- 0.2% of span.
TT230: +/- 0.3% of span when factory calibrated.
Linearity:
Voltage linear.
Ambient Temperature:
Operating: -40 to 85°C (-40 to 185°F ).
Storage: -55 to 100°C (-67 to 212°F ).
Ambient Temperature Effects:
TT190: +/- 0.018% of span°C.
TT230: +/- 0.025% of span°C.
Cold Junction Compensation:
+/- 0.03°C/°C for -25 to 70°C ambients.
+/- 0.06°C/°C for -40 to -25 and 70 to 85°C ambients.
Adjustments:
TT190: Zero and Span, +/- 5% of span.
TT230: Depends on temperature range selected.
Warmup Drift:
+/- 0.2% of span max., assuming Vsupply = 24
VDC and Rloop = 250 ohms. Stable within 30 minutes.
Supply Voltage:
10 to 35 volts DC with no load.
Reverse polarity protected.
Voltage effect:
+/- 0.001% of span per volt.
Maximum Load Resistance:
The maximum allowable
resistance of the signal-carrying loop is given by this
formula: Rloop max = (Vsupply-10)/.02 amps.
Maximum Output Current:
27 mA.
Connections:
Terminal blocks for wires from AWG 22 to
AWG 14.
Physical:
Epoxy potted for moisture resistance.
Weight:
1.8 oz. (58 grams).
Model Number Coding:
TT190 JU 1 K . . . Sample part number
Temperature Range:
Use one of the over 175 range codes in the MINCO Temptran sales
bulletin. Note: A range that is available for a particular Temptran model is not automatically
available for the TT190 or TT230; there may be a nominal charge. Also, ranges available for the
TT190 and TT230 depend on T/C type.
Output:
1 = 4 to 20 mA DC.
Calibrated to match T/C Type:
EU = Type E ( Chromel - Constantan ), Ungrounded Junction
JU = Type J ( Iron - Constantan ), Ungrounded Junction
KU = Type K ( Chromel - Alumel ), Ungrounded Junction
TU = Type T ( Copper - Constantan ), Ungrounded Junction
Model Number:
