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.

◆Bool function,multiple timers,counters,PWM,PI controller,Ramp.Analog math supported.

◆Can be modularly expanded up to 280 I/Os.

◆230V units can be expanded with analog modules.

◆Datalogging:Data from the production process can be saved in SD card of the external accessory called ELC-MEMORY to either read it with a PC or evaluate it from the SD card at the workstation.

◆Extremely simple software

◆Display of up to 128 messages.

◆Multiple kinds of registers can be accessed.

◆Parameters setting menu in LCD panel.

◆Parameters can be modified in the alarming message.

◆Modbus RTU/ASCII protocol supported.

◆Retentive memory capability.

◆Powerful communication capability(1RS232 port,2 RS485 ports(1built-in and 1 need RS485 extension) and 1 expansion port)

◆Password protection.

◆It's optional for xLogic to act as salve or master in certain Modbus communication network.

◆Backup at Real Time Clock(RTC) at 25 ℃:20 days.

◆2 PWM channels optional.

◆Communicate with third party device which supports Modbus network.
