Relay Boards
Z-World’s RELAY6 (XP8300) and RELAY8 (XP8400) expansion
boards provide a simple way to add relays to your control sys-
tem. Up to 64 relay boards can be addressed on a single bus.
The RELAY6 board has six high-power relays installed as stan-
dard equipment. The board has six LEDs that correspond to the
six relays. An LED turns on while the corresponding relay’s
coil is activated.
The RELAY8 board has eight DIP relays installed as standard.
Other types are acceptable. A single LED on the board flashes
any time the board has been addressed.
Relay 6
The RELAY6 board has six 10A SPDT relays. Headers H1, H2,
and H4 connect the external world to the relays. Jumper J1
(along with PAL encoding) determines the board’s bus address.
Jumper J2 affects the relays’ actuation voltage.
