• Output Voltage Range: 24V DC (15V~30V tolerance)
• Maximum Output Current: 2A per channel; 6A total for all channels
• Switching Time: ≤1ms (both ON to OFF and OFF to ON)
• Isolation Level: 2.5kVrms (channel-to-channel, channel-to-power supply, channel-to-backplane)
• Protection Features: Short-circuit protection (auto-recovery), overcurrent protection, 2kV ESD protection (IEC 61000-4-2), 4kV EFT protection (IEC 61000-4-4)
• Power Supply: 24V DC (±10% tolerance); Typical power consumption: ≤7W (full load)
• Operating Temperature Range: -20℃~+60℃
• Storage Temperature Range: -40℃~+85℃
• Communication Interface: Profinet (for 800xA system integration), Modbus RTU (for third-party PLC compatibility)
• Installation Method: 35mm standard DIN rail mounting
• Protection Class: IP20 (module body); Complies with IEC 61010-1 (safety) and IEC 61000-6-2 (EMC immunity)

2. Product Features

• High Current Capacity: 2A per channel enables direct control of mid-power devices (e.g., small motors, solenoid valves) without additional relays, simplifying system design.
• Flexible Configuration: Each channel can be independently set to sinking (NPN) or sourcing (PNP) via software, eliminating hardware modifications and supporting diverse industrial actuators.
• Fast Switching Response: ≤1ms switching time ensures timely control of time-critical devices such as emergency stop relays and high-speed valves in automation processes.
• Enhanced Isolation & Protection: 2.5kVrms galvanic isolation prevents cross-interference and ground loops; integrated short-circuit and overcurrent protection with auto-recovery safeguards both the module and connected equipment.
• Intuitive Diagnostics: Front-panel LED indicators for each channel (output status) and module-level status (power, communication) provide real-time visual feedback, enabling quick fault identification (e.g., shorted wiring, actuator failure).
• Hot-Swappable Design: Supports online replacement (with compatible S800 I/O racks) without system shutdown, minimizing downtime in critical applications.
• Industrial Durability: Flame-retardant ABS housing (UL94 V-0) and anti-vibration design (IEC 60068-2-6: 50Hz, 5g acceleration) ensure reliable performance in dusty, humid, or vibration-prone industrial environments.

3. Application Fields

• Manufacturing Automation: Control of solenoid valves (pneumatic/hydraulic), conveyor belt drives, and robotic grippers in automotive, electronics, and consumer goods production lines.
• Process Industry: Operation of valve actuators (open/close control), pump contactors, and alarm indicators in chemical, oil & gas, and pharmaceutical plants.
• Industrial Machinery: Activation of cooling fans, lubrication pumps, and safety interlocks in CNC machines, presses, and material handling equipment.
• Water & Wastewater Treatment: Control of pump motors, valve actuators, and filtration system switches in water treatment plants and distribution networks.
• Building Automation: Management of lighting relays, HVAC dampers, and access control locks in commercial buildings, data centers, and industrial facilities.

4. Precautions

• Power Supply Compatibility: Ensure the input power is 24V DC (±10%)—overvoltage or reverse polarity will damage the module’s internal circuitry.
• Current Limitations: Do not exceed the maximum current per channel (2A) or total current (6A) to avoid overheating and performance degradation.
• Output Type Matching: Configure the output type (NPN/PNP) correctly to match connected devices; incorrect configuration will result in control failure.
• Wiring Best Practices: Use shielded cables for output lines and route them separately from high-voltage power cables (≥30cm spacing) to minimize electromagnetic interference (EMI).
• Hot-Swap Procedure: Follow system-specific guidelines when performing hot-swap replacement to avoid transient voltage spikes that may affect other modules in the I/O rack.
• Environmental Considerations: Avoid installation near strong magnetic fields (e.g., large motors, transformers) or heat sources exceeding 60℃; ensure proper ventilation to maintain operating temperature within range.
• Regular Maintenance: Periodically inspect terminal connections for tightness and clean the module surface to remove dust accumulation, which can cause overheating or signal interference
