Core functions and technical features

1. Core signal processing function

-Multi type signal acquisition and conversion: Supports synchronous acquisition of analog signals (4-20mA DC, 0-10V DC) and digital signals (DI/DO), with built-in high-precision A/D (analog-to-digital) conversion chip, conversion accuracy up to 16 bits, analog signal acquisition error ≤ ± 0.1%, can accurately capture small signal changes of on-site sensors and transmitters, providing reliable data basis for control decisions.

-Signal conditioning and anti-interference processing: Equipped with dedicated signal conditioning circuits, it can filter, amplify, and isolate the collected raw signals, effectively suppressing electromagnetic interference, voltage fluctuations, and signal attenuation in industrial sites; Adopting optoelectronic isolation technology (isolation voltage ≥ 2500V AC) to achieve electrical isolation between input, output, and power circuits, avoiding signal crosstalk and fault propagation.

-Control instruction execution and feedback: After receiving control instructions from the upper controller, the corresponding analog control signal or digital switch signal is accurately output through the internal driving circuit to drive the on-site actuators (such as solenoid valves, regulating valves, contactors, etc.) to act; Simultaneously collecting feedback signals from actuators in real-time, forming a closed-loop control chain of “instruction execution feedback” to ensure the accuracy of control actions.

-Fault self diagnosis and alarm: Equipped with a comprehensive self diagnosis circuit, it can monitor the module’s power supply status, chip operation status, signal acquisition circuit integrity, and interface communication status in real time. When a fault is detected, it will immediately output an alarm signal through a dedicated alarm pin or communication interface, and record the fault code, making it easy for operation and maintenance personnel to quickly locate the problem.

2. Additional practical features

-Flexible interface adaptation capability: equipped with standardized pin or socket interfaces, compatible with ABB Advant OCS series controllers’ backplane bus and AC 800M series I/O expansion interfaces, supporting plug and play installation; At the same time, custom signal interfaces are reserved, which can be adapted to different types of sensors and actuators through jumpers or software configuration.

-Wide range power supply and environmental adaptability: Supports DC 24V ± 15% wide range power supply and can adapt to different power configurations in industrial sites; The core components adopt industrial grade high weather resistant products, with a working temperature range of -20 ℃~+60 ℃ and a humidity adaptation range of 5%~95% (no condensation), which can operate stably in complex industrial environments.

-Modular integration and easy expansion: adopting standardized size design (compatible with 3U or 4U racks), it can seamlessly integrate with other ABB series functional modules (such as communication modules, power modules) to form a complete control unit; Support parallel operation of multiple modules, achieve data sharing through backplane bus, and meet the expansion requirements of control systems.

-Long term stability and lifespan guarantee: Adopting lead-free soldering technology and high reliability component selection, passing ABB’s rigorous environmental stress screening tests (such as temperature cycling, vibration, impact testing), with an average time between failures (MTBF) of ≥ 100000 hours, ensuring long-term stable operation of the module and reducing maintenance costs.
