PLC Analog Input Relay Output


APB-22MRD DC12V-24V, 14 points digital input (the first 12 points can be analog inputs); I4-I7 can be high-speed ports, 8 points relay output, without LCD 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.

Features of APB series PLC:
• Main module: 12/22/24 points; Extension module: 22 points; With flexible extension function, up to 7 I/O extension modules can be configured,1 voice module, and 1 SMS module;
• Lithium battery can be added to improve the clock holding time;
• In DC12-24v state, the main module can include up to 12 channels of 0-10V voltage type analog input, 2 channels of 4-20mA current type analog input and 2 channels of 4-20mA analog output;
• High speed processing: up to 4 channels 10kHz high speed input and 2 channels 10kHz high speed output;
• Built-in MODBUS protocol, and can connected to SH300 (text display).
