Digital Interface Controller Connectors
The J1 and J1A connectors are used to connect the relay driver board to the controller board. J1
and J1A are interchangeable for ease of usage. When J20 is jumpered, J1A will be utilized,
otherwise, J1 is used.
Relay Drive Connectors
Connectors J2 through J13 are Relay Drive connectors. On each connector, there will be:
1) 6 relay drive outputs capable of 200 mA (410 mA for three or fewer channels)
2) 6 relay indicator inputs which will provide the relay coil status, if applicable
3) 4 relay ID inputs
4) 1 relay reset output, capable of sinking up to 800 mA to reset all relay coils

CAUTION
It is imperative that TTL banks only have TTL devices connected to them. Connecting an
open-collector device to a TTL port will result in damage to the RDB and, potentially, to
other equipment in the test system. Failure to comply with this warning will result in voiding
the manufacturer’s warranty.
Power Connectors
Either J14 or J14A can be used to supply dc power to the relay driver board. PWR_BANKx
voltage can range from 5 V to 45 V.
