XP8400 Getting Started s 35
Controllers with simulated PLCBus ports require special expander cables,
but are as easily connected. Appendix D, Simulated PLCBus Connec-
tion, gives detailed illustrated instructions for connecting relay boards to
controllers without PLCBus ports.
XP8400 Configuration
The XP8400 board holds eight low-
power DIP relays. The relays installed
by Z-World as standard equipment
have the specifications shown in Fig-
ure 5-2.
Header H1 (34 pins) connects
external devices to the relays.
Contacts 1, 7, 8, and 14 of each relay are accessible through header H1.
The relays are numbered 07. Contacts for relay 0 are called CT01, CT07,
CT08, and CT014. The contacts for other relay 1 are named CT11, CT17,
CT18, and CT114, and the contacts for the other relays are named simi-
larly.
Figure 5-3 shows the pinouts for the relay connection pins for each relay.
Figure 5-3. Relay Connection Pins
Jumper settings on header J2 determine the actuation voltage for the
boards relays. When pins 12 are connected, the actuation voltage is
supplied by the +24V line on the PLCBus. When pins 23 are connected,
the actuation voltage is supplied by the VCC line on the PLCBus.
