Introduction
Thermocouple Ranges and Resolution:
RTD Ranges and Resolution (4 and 8 CLS only) :
T/C Break Detection: Pulse type for upscale break detection.
Milliamp inputs: 0-20 mA (3 ohms resistance) or 0-10 mA (6 ohms
resistance), with scaling resistors.
Voltage inputs: 0-12V, 0-10V, 0-5V, 0-1V, 0-500mV, 0-100 mV with
scaling resistors.
Source Impedance: For 60 mV T/C, measurements are within
specification with up to 500 ohms source resistance.
