The module adopts a 32-bit high-performance microprocessor, combined with hardware counting circuit, to achieve real-time acquisition and calculation of pulse signals, with a counting error rate of less than 0.001%. It can accurately convert physical quantity data such as flow rate and speed (such as calculating liquid flow rate and motor speed through pulse number), providing reliable data support for measurement and control in the production process.

2. Flexible signal adaptation and anti-interference design

Four differential input channels support multiple signal types and can be connected to common pulse output devices such as flow meters, encoders, proximity switches, etc. without the need for additional conversion modules; Built in digital filtering and differential signal receiving circuit can effectively resist interference such as electromagnetic radiation and voltage fluctuations in industrial sites, reduce the risk of false counting, and ensure data accuracy.

3. Convenient integration and maintenance

System compatibility: seamlessly integrated into ABB Symphony Plus DCS, supports direct configuration of parameters (such as counting mode, filtering frequency, alarm threshold) through system configuration software, without the need to write complex programs

Status monitoring: The module is equipped with LED indicator lights on the front, which display real-time power status, channel working status, and fault information, making it easy for on-site personnel to quickly troubleshoot problems

Remote diagnosis: supports remote reading of module working status, counting data, and fault codes through DCS system, reducing on-site maintenance workload and improving operation and maintenance efficiency

4. Safety and redundancy design

Built in overvoltage and overcurrent protection circuits automatically cut off the input channel when the input voltage or current exceeds the rated range, protecting the module and backend equipment from damage; Support for use in conjunction with ABB redundant power systems to ensure that modules quickly switch to backup power in the event of power outages, avoiding data loss and counting interruptions.
