Application Scenarios

• Factory automation production lines
• Packaging and printing machinery
• Material handling and conveyor systems
• Small and medium-sized machine tool control
• Building automation and environmental control systems

Installation Requirements

• Mount on standard DIN rail or via panel mounting holes
• Maintain minimum clearance around the unit for heat dissipation
• Operate in an environment free of condensation, corrosive gas and excessive dust
• Use copper conductors with appropriate cross-section for I/O wiring
• Connect functional ground terminal to system ground for EMC compliance

Operating Notes

• Never connect 24 V DC and 100/240 V AC circuits to the same terminal
• Replace the buffer battery periodically to prevent program loss
• Do not exceed the rated load current per common output terminal
• Disconnect all power sources before wiring or maintenance
