Description

Delta AS04RTD-A RTD Temperature Measurement Module for AS Series PLC

The Delta AS04RTD-A is an RTD temperature measurement module designed for Delta AS Series PLC systems. It provides 4 RTD input channels for temperature measurement applications using PT and NI temperature sensors.

This module is suitable for industrial automation systems that require accurate temperature monitoring from field sensors and direct integration with PLC control logic. It is commonly used in machines, process lines, control panels, heating systems, packaging machines, food production lines, water treatment systems, and general industrial applications.

The AS04RTD-A helps the PLC read temperature signals from RTD sensors and use them for monitoring, alarm logic, PID control, heating control, cooling control, and process supervision.

Typical Applications

The Delta AS04RTD-A RTD Module is suitable for:

Temperature monitoring in industrial machines
Heating and cooling control systems
Food and beverage production lines
Packaging machinery
Plastic and textile machines
Water treatment systems
Process temperature monitoring
Tank and pipeline temperature measurement
Oven, heater, and dryer control
PLC control panels requiring RTD temperature inputs
Why Use Delta AS04RTD-A?

The AS04RTD-A is a practical solution when a Delta AS Series PLC system needs multiple RTD temperature inputs. Instead of using separate temperature controllers, this module allows direct temperature measurement inside the PLC system, making it easier to build integrated control logic, alarms, PID loops, and HMI monitoring screens.

It is especially useful for control panels where temperature readings must be connected directly to PLC logic for machine protection, heating control, cooling control, and process automation.
