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
