DO810-eA Digital Output Module  

1. Key Parameters

• Number of Output Channels: 8 independent, isolated channels
• Output Type: Configurable for sinking (NPN) or sourcing (PNP) via software
• Output Voltage Range: 24V DC (15V~30V tolerance)
• Maximum Output Current: 1A per channel; 4A 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
• Power Supply: 24V DC (±10% tolerance); Typical power consumption: ≤6W (full load)
• Operating Temperature Range: -20℃~+60℃
• Storage Temperature Range: -40℃~+85℃
• Communication Interface: Modbus RTU and Profinet (for integration with 800xA system)
• Installation Method: 35mm standard DIN rail mounting
• Protection Class: IP20 (module body); Complies with IEC 61010-1 safety standards

2. Product Features

• Flexible Output Configuration: Each channel can be independently set to sinking (NPN) or sourcing (PNP) via software, eliminating the need for hardware modifications and supporting diverse industrial actuators.
• Enhanced Channel Isolation: 2.5kVrms galvanic isolation prevents cross-interference and ground loops, ensuring stable operation in complex industrial electrical environments.
• Comprehensive Protection: Integrated short-circuit and overcurrent protection with auto-recovery function safeguards both the module and connected devices from damage caused by external circuit faults.
• Fast Response: ≤1ms switching time enables quick control of time-critical devices such as emergency stop relays and high-speed valves.
• Easy Diagnostics: Front-panel LED indicators for each channel (output status) and module power/communication status facilitate rapid fault identification and troubleshooting.
• Industrial Durability: Flame-retardant ABS housing (UL94 V-0) and anti-vibration design (IEC 60068-2-6) ensure reliable performance in dusty, humid, or vibration-prone industrial settings.

3. Application Fields

• Process Industry: Control of solenoid valves, motor contactors, and alarm indicators in chemical plants, oil refineries, and petrochemical facilities.
• Manufacturing Automation: Activation of conveyor belt drives, robotic grippers, and welding machine triggers in automotive and electronics production lines.
• Power Sector: Operation of circuit breakers, cooling fan relays, and status indicators in power distribution systems and renewable energy plants.
• Water & Wastewater Treatment: Control of pump motors, valve actuators, and filtration system switches in water treatment plants.
• Building Automation: Management of lighting relays, HVAC dampers, and access control locks in commercial and industrial buildings.

4. Precautions

• Ensure the power supply voltage is within the 24V DC ±10% range to prevent damage to the module's internal circuitry.
• Do not exceed the maximum current rating per channel (1A) or total current (4A) to avoid overheating and performance degradation.
• Configure the output type (NPN/PNP) correctly to match the connected devices; incorrect configuration will result in control failure.
• Use shielded cables for output lines and connect the shield to protective ground to minimize electromagnetic interference (EMI).
• When replacing the module, follow proper hot-swap procedures if supported by the 800xA system; otherwise, power off the I/O rack first to prevent transient voltage spikes.
• Regularly inspect terminal connections to ensure tight contact, as loose connections can cause intermittent operation or increased resistance
