Advantages
Long life, high operating frequency, short response time and low noise.

Use diaphragm to prevent surge, arc-extinguishing (2-level crystal reverse) RC circuit, anti-burn contact, short circuit protection (safety tube, self-recovery). Low voltage controls high voltage, and small current carries large current.
Applicable occasions
High frequency, many times, small current (1-8A)
Applicable scene
Small motor, industrial heating rod, heating plate, slitting machine, laminating machine, laser machinery, hydraulic machinery, glass machinery, woodworking machinery, access control and other automation equipment.

Product Usage
1. Effectively expand PLC output load capacity. PLC output or programmable MCU cannot achieve high current and high voltage output due to wiring mode and its own volume limitation. Therefore, it is necessary to add expansion board to expand output current and voltage and improve load driving capability. . 2. The direct drive load of the PLC output does not have the functions of isolation and short circuit protection. The PLC amplifier board is added with photoelectric isolation or electromagnetic isolation, short circuit protection, anti-surge and other protection circuits to effectively protect the PLC output points and equipment, and prevent misoperation caused by grid interference signals. 3, can control the DC or AC load arbitrarily, with a common point structure, convenient wiring, space saving, neat and beautiful appearance, saving materials, labor, safety and reliability, is the connection bridge of PLC output, commonly used to drive solenoid valves, Contactors, small motors, hydraulic valves, etc.
