Features

The XP8300 board has six 24V high-power relays installed as standard

equipment: two are configured as SPDT and four are configured as SPST.

All the relays have wire terminals that allow easy connections to external

devices. Each relay is protected with a 10A fuse. To help eliminate noise

transients, a metal oxide varistor (MOV) is attached between pin 1 and pin

3 of each relay.

The inputs (pin 1) and normally open output contacts (pin 3) for all relays

on an XP8300 board are accessible on headers H1 and H2. The normally

closed outputs (pin 4) for relays 4 and 5 are available at header H4.

The XP8300 also has six LEDs that correspond to the six relays. An LED

turns on when the corresponding relays coil is energized. However, an

illuminated LED does not verify that the contacts within the relay actually

switch.

The XP8310 is a 12V version of the XP8300.
