Input relay blocks
•
GND
• Connects directly to common on power terminal strip
• No daisy-chaining GND to other relay blocks or “OR” boards
• Inputs from the PMC464 must have a common connection from the PMC464 (pin 17)
running inside cable bundle
• This common connection from the PMC464 must connect to the relay board’s GND
•
+5V
• One connection directly to +5V power terminal strip
• All additional 5V connections on a single relay input block are daisy-chained within its
own individual input relay block
Output relay blocks
•
GND
• Redundant output
• GND connected to GND point on the “OR” board
• All additional GND connections on a single relay output block are daisy-chained
within its own individual output relay block
• No daisy-chaining GND to other relay blocks or “OR” boards
• Non-redundant output
• GND connected to common on power terminal strip
• No daisy-chaining GND to other relay blocks
• Outputs from the PMC464 must have a common connection from the PMC464 (pin 17)
running inside cable bundle
• Common connection from PMC464 card should connect to its corresponding
output relay block
• Connect PMC464 common to output relay block GND
•
+5V
• N/A
“OR” board
•
+5V
• Connect directly to +5V on power terminal strip
•
GND
• Connect directly to common on power terminal strip
• No daisy-chaining GND to other “OR” boards or relay blocks
• Output from PMC464 must have a common connection (pin 17) running inside the cable
bundle
• Common connection from PMC464 connects to its corresponding “OR” Board
•
Twist 5V and GND cables together before connecting to power terminal strip
Power supply
•
+5V
• Connect directly to +5V on power terminal strip
•
GND
• Connect directly to GND on power terminal strip
