Safety and Installation Precautions

Because ILOGICS products are used in industrial equipment, safe operation requires consideration of power, wiring, protective circuits, and risk assessment of the entire machine, as well as correct program operation.

• Turn off the power before wiring, connecting modules, or changing DIP switches.
• Distinguish supply voltage, input voltage, load voltage, current per point, and total COM current.
• Do not infer electrical ratings from other models when they are not specified in the product manual.
• Provide separate back-EMF and inrush-current protection for inductive loads.
• Implement emergency stops, overcurrent protection, interlocks, and any required redundant safety circuits independently of the MCU.
• Design the circuit and program so the equipment enters a safe state when outputs are OFF.

The relay contact component's maximum rating is not a product rating valid for every load. Transistor outputs use an N-CH FET SINK configuration and require an external load supply and COM wiring.

Confusing the DIP-switch settings or wiring for voltage and current inputs can damage the product and connected equipment. Before connecting a signal, verify its actual type and range with a multimeter.

Ask ILOGICS about any explosion protection, ingress-protection rating, dielectric strength, operating temperature/humidity, certification, wire size, or tightening torque not specified in the current product documentation.
