FPC – N64 (Typical) 250mA 125mA
NOTE: These values are ‘nominal’ and a safety margin should be added to the power supply of the host system.
A safety margin of 25% is recommended.
Apply power to the ProtoNode as shown below. Ensure that the power supply used complies with the specifications
provided in Section 12.4 Specifications.
• The gateway accepts 9-30VDC or 24VAC on pins L+ and N-.
• Frame GND should be connected to ensure personnel safety and to limit material damages due to electrical faults.
Ground planes are susceptible to transient events that cause sudden surges in current. The frame ground connection
provides a safe and effective path to divert the excess current from the equipment to earth ground.
NOTE:Floating AC Power Supplies are supported.
