- RIEVTECH
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(1 built-in&1 need RS485 extension ,and 1 IO 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.
