• Storage mechanical condition: No heavy extrusion, drop or collision allowed during handling and transportation.

3. Full Electrical Specifications

3.1 Power Supply Parameters

• Rated operating voltage: 24 V DC (supplied uniformly through backplane internal power bus);

• Allowable voltage fluctuation range: 18 V DC ~ 30 V DC;

• Typical power consumption: Moderate stable power load, will not overload System 2003 dedicated rack 24 V power supply unit;

• Real-time clock backup: Built-in onboard backup battery, maintain RTC timestamp, fault log time mark and recipe data retention under short-time power failure; battery is replaceable during maintenance.

3.2 Internal Backplane Bus Electrical Performance

• Realize cyclic synchronous data exchange with all rack slave modules: 7AI analog input, 7AO analog output, digital I/O, counter modules, 7CM communication modules such as 7CM411.70-1;

• Bus cycle scheduling managed entirely by CPU core, allocate communication bandwidth and task priority for multi-module synchronous sampling and actuation;

• Full galvanic isolation between CPU core circuit and backplane signal bus, suppress ground loop interference.

3.3 Interface Electrical Characteristics

1. Programming debug interface: Isolated communication port, dedicated differential signal, independent from control bus, no interference to machine control during online downloading and monitoring;

2. No onboard native fieldbus physical ports: External fieldbus (for servo drives, HMIs, remote I/O) must be expanded via 7CM series pluggable communication slave modules;

3. All internal signal circuits adopt EMC filtering, surge protection and reverse connection prevention design; terminal contact pins are gold-plated for long-term anti-oxidation and stable conduction.

3.4 Electrical Protection Circuits

• Overvoltage protection: Suppress transient voltage surge from power grid and drive switching;

• Overcurrent protection: Internal fuse and chip overcurrent shutdown mechanism to avoid core circuit burnout;

• Reverse polarity protection: Prevent damage caused by reversed 24 V DC power wiring;

• ESD electrostatic protection: Meet industrial EMC level, resist static electricity generated by human operation and cabinet equipment switching.

4. Environmental Operating Conditions (Mechanical & Electrical Adaptation)

• Continuous working ambient temperature: 0 ℃ ~ +60 ℃;

• Storage and transportation temperature: -25 ℃ ~ +70 ℃;

• Ambient humidity: 5% ~ 95% non-condensing;

• Forbidden environments: Corrosive chemical gas, long-term high humidity, heavy dust accumulation, liquid splashing, flammable and explosive atmosphere; if applied in harsh workshops, must equip fully sealed protective cabinet with heat dissipation fan.

• Wiring requirement: Programming cables and external fieldbus cables must use shielded twisted-pair wire to guarantee long-distance communication stability.

5. Core Electrical Control Functions

1. Program operation: Execute Automation Studio compiled application programs, complete sequential logic, safety interlock, PID closed-loop regulation, batch counting and fault diagnosis arithmetic;

2. Motion control: Multi-axis interpolation, position/speed/torque closed-loop calculation, send motion commands to ACOPOS servo drives through 7CM bus modules;

3. Data storage: Onboard non-volatile memory stores user programs, production recipes, machine parameters and historical fault logs;

4. Fault safety response: Real-time monitor power, bus, program and module status; trigger safe stop of axes and cut off actuator outputs once critical fault occurs to protect machine and operators;

5. System task scheduling: Distribute cycle tasks of logic, motion, I/O sampling and communication to ensure high-precision synchronous control.

6. Compatible System 2003 Hardware Matching

1. Full series 7BP DIN rail backplanes;

2. 7AF104.7 analog adapter bases, matched with 7AI analog input, 7AO analog output submodules;

3. System 2003 digital input and digital output submodules;

4. Counter, encoder and positioning expansion modules;

5. 7CM fieldbus communication expansion modules (typical model 7CM411.70-1);

6. 7AC020.9 blank slot protective baffles for unused backplane positions;

7. Special 24 V DC rack power supply for System 2003 racks.

   Unoccupied slots must be covered with baffles to stabilize backplane bus impedance, prevent pin oxidation and dust intrusion which degrade electrical communication reliability.
