Mounting & Installation Guidelines

• You can mount the module in either a vertical or horizontal orientation, but this affects the total current rating.
• For vertical mounting, the maximum output current is 600 mA at 30°C and 300 mA at 60°C ambient temperature.
• For horizontal mounting, the maximum output current is 300 mA at 30°C and 150 mA at 60°C ambient temperature.
• The module uses a removable terminal strip for easy wiring and module replacement.
• Always verify your device's voltage and current requirements before connecting them to the output channels.
