Specifications
The following section contains specifications for inputs, outputs, the
serial interface, system power requirements, environmental
specifications, and the CLS physical dimensions.
Analog Inputs
Number of Control Loops: 4 (4CLS), 8 (8CLS), 16 (16CLS), plus one
pulse loop.
Number of Analog Inputs: 4 (4CLS), 8 (8CLS), 16 (16CLS).
Input Switching: differential solid state MUX switching.
Input Sampling Rate:
4CLS: 6x/sec (167 ms) at 60 Hz; 5x/sec (200 ms) at 50 Hz.
8CLS: 3x/sec (333 ms) at 60 Hz; 2.5x/sec (400 ms) at 50 Hz.
16CLS:1.5x/sec (667 ms) at 60 Hz; 1.25x/sec (300 ms) at 50 Hz.
Analog Over Voltage Protection: +20 V referenced to digital ground.
Common Mode Rejection (CMR): For inputs that don't exceed +5 V,
>60 dB DC to 1 kHz, and 120 dB at selected line frequency.
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.
