Terminals
This section covers the arrangement and wiring of terminals on the Terminal
Blocks for control and alarm outputs. For obtaining signals from control outputs
or alarm outputs, the signals shown below can be output by connecting
through-type Terminal Blocks (XW2B-20G4 or XW2B-20G5). Secure the lead
wires so that they do not make contact with the product. If they touch the product
or other items they may cause damage.
The diagram shows the terminal arrangement for a XW2B-20G5, but the num-
bers are the same for a XW2B-20G4.
Do not use terminals 1, 2, 5, 7, and 9. Using these terminals may result in internal
damage, so leave them open.

G7TC-OC16, G7TC-OC08, and G7VC-OC16 I/O Terminals do not have an in-
ternal power supply. Connect the relay drive power supply to the plus and minus
terminals. Even if relays for 24 VDC are used, noise resistance can be strength-
ened by providing separate power supplies to the E5ZD and the I/O Relay Termi-
nal instead of providing them with a common power supply. In addition, provide a
power supply at the load (contacts) that corresponds to the load. Outputs 8 to 12
cannot be received when a G7TC-OC08 is used.
