Compatible with FOXBORO 800 series and EVO series control systems, supporting seamless integration with upper computer SCADA systems, PLC and HMI devices. The open interface design facilitates system upgrades and functional expansion, adapting to industrial automation scenarios of different scales.

5. Design assurance for safety and compliance

As a control component that can be used in safety interlock systems, its design fully complies with SIL 4 safety level requirements. It can detect the real-time operation status of equipment through logical operations, and quickly trigger protection mechanisms when abnormalities occur. It sends a "track idle/not idle" signal to the emergency stop circuit. At the hardware level, it has overcurrent, overvoltage, and short-circuit protection functions, while at the software level, it supports program backup and fault self diagnosis to reduce system operational risks.

Working principle

The combination control board has the core workflow of "signal acquisition logic operation instruction output state feedback", and achieves closed-loop control through the collaborative work of SY-0301059F logic control module and SY-1025115C/SY-1025120E I/O module. The specific principle is as follows:

1. Signal acquisition stage

The SY-1025115C module serves as the input processing unit, responsible for receiving on-site sensor signals: four analog input channels collect continuously changing physical quantities such as temperature, pressure, and flow rate, which are converted into 0-5V standard voltage signals through signal conditioning circuits; The 8-channel digital input channel collects discrete signals such as start stop status and limit switches of the equipment, and transmits them to the core control unit after eliminating interference through a photoelectric isolation circuit.

2. Logical operation stage

The SY-0301059F logic control module serves as the core unit and executes preset control programs based on a 32-bit microprocessor. It is composed of instruction registers, decoders, and timing generators internally. The decoder analyzes the control logic corresponding to the input signal and drives the combinational logic circuit to perform operations by combining the beat signal generated by the timing circuit. For example, when the pressure sensor signal exceeds the threshold, the system automatically triggers the PID algorithm to calculate the optimal output control quantity.

3. Instruction output stage

The calculation result is transmitted to the SY-1025120E output module, and the analog output channel converts the control quantity into a 4-20mA current signal to drive the actuator (such as regulating valve, frequency converter) to act; The digital output channel outputs switch signals through relays to control the start stop, fault alarm, and other operations of the equipment. At the same time, the output module collects real-time feedback signals from the actuator to form a control loop.

4. Communication and Monitoring Stage

The control board interacts with the upper system through a standard industrial communication interface to upload equipment operating parameters (such as input and output signal values, alarm information) to the HMI or SCADA system, while receiving control parameters (such as PID set values, start stop commands) issued by the upper computer. When a module malfunction or signal abnormality is detected, the local alarm indicator light is immediately triggered and a fault code is sent through the communication port for easy troubleshooting by operation and maintenance personnel.

Precautions

1. Installation and environmental precautions

-The installation environment should meet the requirements of a temperature of -40 ° C to 70 ° C and a relative humidity of 10% -90% (no condensation), avoiding direct sunlight, corrosive gases, large amounts of dust, and strong vibration environments. If necessary, protective control cabinets should be installed and ventilation and heat dissipation should be strengthened.

-When installing with DIN rail, it is necessary to ensure that the buckle is firm. In frequent vibration scenarios, additional M3 screws should be used for fixation, and the tightening torque of the screws should be controlled at 0.5-0.8N · m to avoid damaging the module due to over tightening or causing poor contact due to over loosening.

-Control circuits and communication cables should be kept at a distance of at least 100mm from power cables to avoid parallel installation and prevent signal distortion caused by electromagnetic interference.

2. Wiring and power operation specifications

-Before wiring, all external power sources (including main and backup power sources) must be cut off, and live operation is strictly prohibited. After wiring is completed, terminal protection covers must be installed to prevent the risk of electric shock.

-The power wiring needs to distinguish between positive and negative poles. Reversing the positive and negative poles of the 24V DC main power supply will cause the module to burn out; It is recommended to connect a 10A fuse in series in the power circuit to avoid overcurrent damage to the equipment.

-The input and output signal lines need to use shielded cables, with the shielding layer grounded at one end; The terminal wiring should use matching solderless terminals, and the tightening torque should be controlled at 0.3-0.5N · m to prevent loose wiring and poor contact.

3. Operation and maintenance taboos

-Module plugging and unplugging is only supported in the power-off state, and hot plugging operations will cause internal circuit breakdown; When replacing modules, it is necessary to wear an anti-static wristband to avoid damaging the IC chip due to human static electricity.

-It is prohibited to directly touch the solder joints, connectors, and electronic components on the circuit board with hands. Idle modules should be stored in anti-static packaging bags to avoid storage in humid environments.

-After modifying the control program, offline simulation testing is required to confirm that the logic is correct before downloading it to the control board to avoid equipment misoperation caused by incorrect programs.

4. Safety and fault handling

-An independent emergency stop circuit and safety interlock circuit must be configured outside the control board, and the internal protection function of the module cannot be relied solely on to ensure that the equipment can be safely shut down in case of power failure or module abnormality.

-When a communication failure occurs, first check the firmness of the wiring and the configuration of the communication protocol, and then use specialized tools to detect the communication bus voltage; When abnormal input and output signals occur, prioritize troubleshooting sensor/actuator faults before checking module channels.

-Module failures should be repaired by professional technicians. It is prohibited to disassemble the casing or solder the circuit without authorization. When repairing, the same model of spare parts should be used for replacement to avoid mixing modules of different specifications that may affect system compatibility.
