2.3 – INPUTS/OUTPUTS
Analog Input . Analog input for temperature is available
and field configurable via jumper for 0-5VDC, 0-10VDC, or
4-20mADC.
Analog Outputs . Transmitter/AUTO-cal Reporting,
Temperature, Absolute Pressure, and one selectable
output are individually configurable via jumper for 0-5VDC,
0-10VDC, or 4-20mADC.
Digital Inputs . Dry contacts input from "smart" relay for
AUTO-purge start signal and AUTO-cal external start.
Digital Outputs . Dry contacts for optional Alarm or AUTO-
purge activation/acknowledgment. Contacts are rated for:
Maximum 3 amps @ 24 to 120VAC
Maximum 3 amps @ 24VDC
Maximum 0.5 amps @ 48VDC
Temperature Compensation Selection . Push-button
selection of linearized or non-linear input. Choice of
thermocouple or 100 ohm platinum RTD temperature
sensor type.
Type E -50 to 1750ºF -50 to 950ºC
Type T -50 to 750ºF -50 to 400ºC
Type J -50 to 2000ºF -50 to 1090ºC
Type K -50 to 2000ºF -50 to 1090ºC
RTD -50 to 1500ºF -50 to 815ºC

Span Rangeability . The calibrated span can be down
ranged to 40% of the Natural Span.
Accuracy . ±0.1% of Natural Span, including non-
linearity, hysteresis, and non-repeatability.
Stability . ±0.5% of Natural Span for six months.
Transducer Response Time . 0.5 second to reach
98% of a step change.
Temperature Effect . Zero. None; corrected by AUTO-
zero. Span. 0.015% of Full Span/ºF.
Mounting Position Effect . None; corrected by AUTO-
zero.
Span and Zero Adjustment . Digital, via internally
located push-buttons.
Automatic Zeroing . Accuracy. Within 0.1% of
calibrated span. Frequency. Every 1 to 24 hours
selectable on 1 hour intervals.
Low Pass Filtration . Response time to reach 98% of a
step change is adjustable from 2.0 to 256.0 seconds.
Overpressure and Static Pressure Limit . 25 psig.
Temperature Limits . –20 to 180ºF Storage.
+40 to 140ºF Operating.
Humidity Limits . 0-95% RH, non-condensing.
2.2 – INDICATION
