6.1 Overview
6.1.1 Characteristics
This section describes the specifications for temperature measurement modules, their operation, and their
programming. The AS04/06RTD is a temperature measurement module that converts the temperatures
received from four/six thermocouples into digital signals. You can select either Celsius or Fahrenheit as the
unit of measurement.
6.1.2 Characteristics
(1) Select a sensor based on its practical application.
Pt100/Ni100/Pt1000/Ni1000/JPt100/LG-Ni1000/Cu50/Cu100/0–300 Ω/0–3000 Ω sensor
(2) High-speed conversion
Two-wire/Three-wire configuration: 200 ms/channel
(3) High accuracy
Conversion accuracy: The error range of the input is ±0.1% at ambient temperature of 25° ±5° C.)
(4) Disconnection detection
When a sensor is disconnected, the AS04RTD produces an alarm or a warning.
(5) PID control
An object’s temperature can be maintained through PID control actions.
(6) Use the utility software to configure the module.
The HWCONFIG utility software is built into ISPSoft. You can set modes and parameters directly in
HWCONFIG without spending time writing programs to set registers to manage functions.
