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.

The relays installed by Z-World have the following specifica-
tions:

Configuration: SPDT
Coil Actuation Voltage: 24 VDC
Pin 5 connects to the high-current (sinking) driver on the relay
board. Pin 2 is for the actuation voltage. Turning on the sink al-
lows current to flow through the coil, switching on the relay.
Pin 3 is the normally open output. Pin 4 is the normally closed
output. Pin 1 is common to N.O. and N.C. outputs.

Each relay is protected by a 10A fuse. To reduce or eliminate
transients, a metal oxide varistor (MOV) is connected between
pins 1 and 3 on each relay.
Headers H1, H2 and H4 connect your system’s devices to the re-
lays. Pin 1 (common) and pin 3 (N.O.) connections for all six
relays are provided on H1 and H2. Header H4 provides the pin 4
(N.C.) connections for relays 4 and 5.

Jumper J2 affects the actuation voltage for the board’s relays.
When J2:1-2 is connected, the actuation voltage is supplied by
the +V line on the PLCBus. When J2:2-3 is connected, the ac-
tuation voltage is supplied by the VCC line on the PLCBus.
To supply actuation voltage at header H3, leave J2 unconnected
and connect your power supply at V+ and GND.
Relay 8
The RELAY8 board has eight 500 mA DIP relays. Header H1 (34
pins) connects 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.
