The following list details the
equipment required for board validation:
- 240 VAC to 24VAC or 120 VAC to 24
VAC, 20VA isolation transformer (20 VA is selected to supply less than 100 mA
per SSR with a maximum of six SSRs on at a time). If the power relay coil
current is more than 100 mA and if it is required to run the entire relays ON at
a time, a transformer with increased VA rating must be used.
- Separately isolated 40-V, 1.5-A
DC supply and 5-V, 0.2-A DC supply
- 24-V AC power relay (with coil
current less than 1 A) – multiple quantity
- MSP430FR2355 LaunchPad™ or similar
controller or function generator to generate relay control signals
- Oscilloscope (100 MHz) with two
or more isolated voltage probes
- 4½ digit multimeter
