Inputs
Temperature Compliant to GSIE temperature probes
Accuracy of ±0.1ºC in a normal operation
Allowable loss of performance in a noisy environment:
Accuracy of ±0.65ºC from initial reading with a fixed resistor of 1% precision used for test-
ing purpose.
Analog 0-5 Volts Sensor must be able to drive a 2k Ohms load, which means the sensor must drive at least
2.5mA to ensure correct readings.
Accuracy of ±30mV in a normal operation.
Allowable loss of performance in a noisy environment:
Accuracy of ±80mV from initial reading with a voltage source of 1% precision used for test-
ing purpose.
Analog 4-20mA Sensor must be able to drive a 120 Ohms load
Maximum rating: 20.8mA, 2.5V
Accuracy of ±0.2mA in a normal operation.
Allowable loss of performance in a noisy environment:
Accuracy of ±0.4mA from initial reading with a current source of 1% precision used for test-
ing purpose.
