Table 1.1—General Specications
RTD Inputs 2 channels
100-ohm platinum RTD with 2-wire, 3-wire, or 4-wire interface
Range: –40 degC to 427 degC (–40 degF to 800 degF), excluding RTD uncertainty
Accuracy: ± 0.2 degC (0.36 degF) over sensing range at calibrated temperature
Temperature effect: ± 0.3 degC (0.54 degF) over operating range
A/D resolution: 24 bits
Sample rate: 0.1 seconds to 12 hours
Congurable shutoff for power savings when transducer warm-up period is not required
Pulse/Frequency
(TFM) Inputs
3 channels
Maximum voltage: 30 VDC
Maximum frequency: 10,000 Hz
Gated transmitter power for each input channel
Transmitter voltage supply: 10 VDC at 20 mA, protected to 50 mA
TFM Channel 3 has no sleep mode and increased power consumption
Accumulation types: uncompensated gas volume, uncompensated liquid volume, mass
Volume: pulse represents discrete units of volume from a turbine, PD, Venturi, Coriolis, or
ultrasonic meter
Mass: pulse represents discrete units of mass from a Coriolis meter
Congurable turbine sensitivity (20, 50, 100 mV, peak-to-peak)
Analog Outputs 2 channels
Type 4 to 20 mA, optically isolated, externally powered
Accuracy (after calibration): ± 0.1% of span maximum error at 25 degC (77 degF)
Temperature drift: ±50 ppm/degC (±27.8 ppm/degF)
Maximum output load resistance (ohms) = {supply (volts) – 8.0} / 0.02
Maximum voltage: 30 VDC
D/A resolution: 16 bits
Calibration (zero and full-scale) via software
Programmable output alarm value for use during loss of power or communication to CPU
Regulates control valve in PID control applications
