Switching Pulse Counting Acquisition and Transmission Module counting acquisition and transmission module is a multi-functional device tailor-made for counting needs in industrial scenarios. It integrates counting, alarm control, data transmission, and communication capabilities in one. Equipped with a built-in 24V power supply port, the module can directly provide a stable 24V DC voltage and 30mA DC current for external sensors, eliminating the need for additional power configuration and simplifying on-site wiring.
In terms of core functions, the module supports accurate counting of discrete signals or level pulse signals (high level: +4V~+30V; level voltage must be specified when placing an order) output by devices such as encoders, photoelectric switches, and proximity switches. The display range can be flexibly adjusted by setting Multiplier A, Multiplier B, and 7-digit decimal points, meeting counting requirements for different measurement ranges. Meanwhile, the module is equipped with 2 channels of relay output and 2 channels of 16-bit high-precision DA transmission output, which can customize alarm actions and analog signal conversion based on count values. Relying on the photoelectrically isolated RS-485 communication interface, it can seamlessly connect to upper-level devices such as industrial computers, touch screens, and PLCs, realizing real-time transmission of counting data and remote control. In addition, the design of 2 channels of custom DI input further expands the module's adaptability in complex industrial scenarios, and it is widely used in counting monitoring and process control in fields such as mechanical processing, assembly line production, and warehousing logistics.
