*For DC current input, 100 Ohms (0.1%, 25 ppm) shunt resistor must be connected
externally. For DC current and Voltage input, Scaling is possible and decimal point is
selectable.
Sampling Period: 100mSec for TC and Linear Input, 200mSec for RTD Input.
Resolution: 17-bit
Burnout detection: Functions for TC, RTD, linear input signal. (It detects whether
sensor is connected or not) ALL Relay output can be selected for Burnout Condition.
i.e. Open sensor Up scale or Down Scale
Measurement current (RTD): 1milli Ampere
