Detailed content
Technical Specifications:
- Number of Channels: 24 digital outputs
- Output Type: Transistor (NPN/PNP selectable)
- Output Voltage: 24 V DC nominal
- Maximum Load Current per Channel: 0.5 A
- Total Module Current: 8 A maximum
- Isolation Voltage: 500 V DC between channels and backplane
- Response Time: < 1 ms per channel

- Supply Voltage: 24 V DC ± 20%
- Dimensions (W x H x D): 120 mm x 90 mm x 65 mm
- Weight: Approximately 280 g
Structural Features:
- DIN rail mounting (EN 50022 standard, 35 mm rail)
- Spring-loaded terminal blocks for wire connection
- LED status indicators per channel group (8 groups of 3)
- Modular front-loading design for hot-swap capability
- Plastic housing made from flame-retardant polycarbonate (UL94 V-0)
Working Principle:
The module receives digital control signals from the PLC via a backplane bus. Each output channel uses a photocoupler-isolated transistor driver to switch the load. The NPN/PNP configuration is set via DIP switches on the module front.
Key Advantages:
- High channel density (24 outputs in compact form factor)
- Galvanic isolation on every channel for noise immunity
- Hot-swap capable without system shutdown
- Diagnostic LEDs for rapid fault identification
Applicable Industries:
Manufacturing automation, packaging machinery, water/wastewater treatment, HVAC control, material handling systems.
Installation Requirements:
- Mount on 35 mm DIN rail (EN 50022)
- Ensure adequate ventilation (minimum 10 mm clearance above and below)
- Use shielded cables for output wiring in high-EMI environments
- Torque terminal screws to 0.5 Nm
Usage Precautions:
- Do not exceed 0.5 A per channel or 8 A total module current
- Verify NPN vs PNP wiring before energizing
- Do not connect inductive loads without flyback diodes
- Maintain operating temperature within -25°C to +70°C
