APPENDIX D: WIRING EXTERNAL OUTPUT RELAYS
OUTPUTS
The outputs can be wired thru an external relay(s) (not included) to switch on/off inductive loads.
There are two ways to drive the external relay(s):
1. Using internal power supply from TI-1680
2. Using an external power supply (not included)
If you are using the internal power supply, then your relay must be able to operate with 5VDC.
