XP840030 s Overview
Z-Worlds XP8400 expansion boards provide a simple way to add relays to
a control system built around a Z-World controller. These relay output
boards can be connected on the PLCBus in conjunction with other expan-
sion boards. The actuation voltage for the boards relays comes from the
controller via the PLCBus port. The XP8400s eight relays are low-power
relays.
Figure 4-1 illustrates a system of expansion boards mounted on a DIN rail
and connected to a controller. Chapter 5, Getting Started, provides
instructions and illustrations for connecting a relay board to a controllers
PLCBus port. Appendix D, Simulated PLCBus Connection, provides
instructions and illustrations for connecting relay boards to a specific
controller that does not have a PLCBus port.
