Specifications
This section contains specifications for inputs, serial interface, system
power requirements, environmental specifications, and physical
dimensions.
Analog Inputs
Number of Analog Inputs: 16 single-ended/ common ground, plus one
pulse input.
Input Switching: solid state MUX switching.
Input Sampling Rate: 1.5x/second (667 ms) at 60 Hz; 1.25x/second
(300 ms) at 50 Hz.
Analog Over Voltage Protection: ±20 V referenced to digital ground.
A/D Converter: Integrates voltage to frequency.
Input Range: -10 to +60 mV. Other ranges are available with scaling
resistors.
Resolution: 0.006%, greater than 14 bits. (This is the internal
measurement resolution, not the display resolution.)
Calibration: Automatic zero and full scale.
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.
