Micro PLC Rievtech Programmable relay PR24-AC-R Small Relay with Expandable Mini PLC

 PR- 24 range(Micro PLC) is advanced level model, incorporating a good mix of digital and Analogue IO, Integrated High Speed inputs
 and PWM output,clock with calendar, counters , timers , integrated keypad display, serial communications and an expansion port.
 Available in 120V/240VAC or 12V/24VDC versions ; Easy to configure with drag-and-drop function blocks using FREE xLogicSoft software.Program capacity has been enlarged to 1024 function blocks as well, also high-speed count reaches 60KHZ. 
 
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.
