PLC Analog Input Relay Output with LCD


APB-22MRDL 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, with LCD PLC
(1) The running speed is fast. Since the control of the PLC is controlled by the program, regardless of its reliability or operating speed, the relay logic control cannot be compared.
(2) The input/output function modules are complete. One of the biggest advantages of PLC is that for different field signals (such as DC or AC, switching, digital or analog, voltage or current, etc.), there are corresponding templates for industrial devices (such as buttons and switches). , sensor current transmitter, motor starter or control valve, etc.) are directly connected and connected to the CPU motherboard through the bus.
(3) Programming is easy. PLC programming mostly uses relay control ladder diagrams and command statements, the number of which is much less than the microcomputer instructions. In addition to medium and high-end PLCs, there are only about 16 small PLCs in general. Due to the simplicity of the ladder image, it is easy to master, easy to use, and even requires no computer expertise to program.

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 1SMS 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;
• Built-in MODBUS protocol, and can connected to SH300 (text display);
• New function blocks: pulse modulation PWM, pulse output PTO, trapezoidal acceleration/deceleration ACC, short message module SMS and analog calculation, etc.
