DC Input 20 Points Micro PLC


AF-20MR-E2 DC12/24V, 12 points DC input 8 points relay output (without analog input) micro PLC
The hardware of the PLC controller itself adopts the building block structure, with motherboard, digital I/O template, analog I/O template, special positioning template, barcode identification template and other modules. Users can expand on the motherboard as needed. Or use the bus technology to equip the remote I/O slaves to get the desired number of I/Os.
While implementing various I/O controls, the PLC also has the ability to output analog voltage and digital pulses, enabling it to control a variety of servo motors, stepper motors, variable frequency motors, etc. that can receive these signals, plus a touch screen. Human interface support.
