Installation & Wiring Guidelines

• Install the module in an enclosure maintaining the 0-60°C ambient range
• Use proper 24V DC power supply within the 19.2-30V operational window
• Do not exceed 0.5A continuous current per output channel
• Implement appropriate fusing for each output group based on load requirements
• Follow the inductive load formula for switching solenoids or relays above 0.5Hz
• Ensure all field wiring uses correct gauge for the 0.5A load current
• Maintain separation between DC output wires and analog signal cables
• Verify all connections are secure to prevent voltage drop issues

Professional Questions & Answers

What does "negative logic (sink)" mean for wiring?

• The module switches the negative side (0V) of the load. The load's positive side connects directly to the 24V DC supply, and the module provides the path to ground when activated.

How do I calculate heat dissipation for my cabinet?

• The module dissipates a fixed 7W plus load-dependent heat. At full load (19.2A), total dissipation is approximately 7W + (19.2A × load voltage drop). Ensure adequate cabinet cooling for continuous operation.

Can I connect inductive loads directly to the outputs?

• Yes, but you must calculate using the provided formula. For example, switching a 0.5A solenoid at 2Hz requires inductance below 0.25H. Always use suppression diodes or varistors for inductive loads.

What happens during a short circuit on one output?

• The built-in protection limits the current and the module reports a fault. The specific channel's LED may indicate the issue, and the fault word in the controller can be programmed for system response.

Is this module suitable for high-speed switching applications?

• With a 0.1ms response time, it can handle moderately fast switching. However, for very high frequencies above 4Hz with inductive loads, consult the inductance formula to avoid damage from voltage spikes.
