Product Description

Micro PLC PR-24 series (Expandable Range)series overview:

PR-24 range offers 4-line*16 characters LCD display and keypad for program modification or display and control whilst program is running. An expansion port allows the connection of up to 16 expansion modules, extending the I/O channel count. Now it is also possible to use the analog output module to solve simple closed-loop control tasks.

Heating and cooling systems can be designed with the RTD PT100 module using special functions for PI control,ramp response and analog multiplexer.

Highlight of PR-24 Series

◆70 ready-to use functions integrated-no additional devices such as operating hours counter required.

◆Extremely large program capacity:up to 1024 functions possible.

◆12 digital inputs(incl 6AI with 12/24V DC)and 6 digital outputs on board.

◆Flexibly expandable up to 142DI,138DO,72AI,and 32AO.

◆Display of message texts,actual and set-point values and direct modification of the values on the display(not on pure variants).

◆Integrated data retentivity-ensures backup of the current values in the event of a power failure.

◆Customizable Start-up page/screen.
