12-8 IO64 Hardware Reference
Digital Outputs
The IO64 provides 32 Dry-Contact Relay Outputs for discrete control.
Note : The Relay Outputs on the IO64 are not polarity-sensitive; therefore,
positive and negative voltages may both be connected to either the top or bottom
socket of the Phoenix connector.
The Relay Outputs are fused at 900mA using self-restoring polymer fuses. If an
overload occurs, the fuse will open until the problem is corrected; then heal
itself.

Connecting an output to a non-inductive load
1. Using a Male Phoenix Connector, connect the appropriate Output pin (top
pin 1 for Output1, top pin 2 for Output2, etc.) on the Outputs Phoenix
Connector to the positive terminal of the external power supply.
2. Using a Phoenix Connector, connect the corresponding Output Return pin
(bottom pin 1 for Output1, bottom pin 2 for Output2, etc.) to the positive
terminal of the device that is receiving the output signal.
3. Connect the negative terminal of the device that is receiving the output
signal to the negative terminal of the external power supply.
