Notes:
1. Solid state relay output; can source or sink current. See Figure C-1.
2. Opto-isolator with emitter input and a series resistor to limit current. See Figure C-2.
3. To realize a high logic input, a typical current of II = 1mA is required; that translates
to a minimum of VIH = 3V.
4. For VI = VIH > 10 VDC an external series resistor is required as shown in Table C-1.
5. Connect RELAY and DIGITAL IO Ports only to Class III or Class 2 circuit.
