Input Types
|
Thermocouples: J, K, C, R, S, T, B, L, N, PtRh20%vsPtRh40%; RTD: 3 - wire PT100, with each wire having a maximum resistance of 50Ω (the three wires should be balanced); Linear DC: 0 - 20/4 - 20mA, 0 - 50/10 - 50mV, 0 - 5/1 - 5/0 - 10/2 - 10V. The range is - 1999 to 9999, and the decimal point position is adjustable
|
|
Input Impedance
|
>100MΩ for thermocouple and mV input, 47KΩ for V input, and 5Ω for mA input
|
|
Sampling Frequency
|
4 times per second, 14 - bit A/D accuracy
|
|
Sensor Open - Circuit Detection
|
<2 seconds (except for short - circuit in DC input). The control output is turned off. For thermocouple and mV input, high alarm is displayed; for PT100, V, and mA input, low alarm is displayed
|
|
Output Signals
|
