I/O Block Details
Input Blocks
G7TC-ID16
G7TC-IA16
Supply power to terminals 0 through 15
and C0 through C15 according to the
voltage specifications of the I/O Relays
and I/O Block. Do not reverse positive
and negative terminals on the DC Input
Block (0 through 15 are positive; C0
through C15, negative). Shorting bars
are available.
Supply to the power terminal (positive
and negative) the rated voltage of the
controller’s input circuits (24 VDC or 12
VDC). Use a low-noise power source.
When using a Connecting Cable with
two connectors, be sure to use the Cable
for Input Blocks. Using the Cable for
Output Blocks may result in malfunction
or damage to the product.

Output Block
G7TC-OC16(-1)
G7TC-OC08
There are voltage specifications for the
Relays and Terminals. Depending on
the controller connected, select either
12 or 24 VDC.
Supply power to contact output
terminals 0 through 15 and C0 through
C15 according to the requirements of
the loads. A 4 terminal Shorting Bar is
available.
Supply to the power terminals (positive
and negative) power both for driving the
relays and for controller output
transistors. Match the controller and I/O
block voltage specifications. Use a low-
noise power source.
When using a Connecting Cable with
two connectors, be sure to use the Cable
for Output Blocks. Using the Cable for
Input Blocks may result in malfunction or
damage to the product.

Output Block Unit G7TC-OC08 does not
have terminals 8 through 15 and C8
through C15. Although a 20-pin
connector is used, pins 11 through 18
are not connected.
When an I/O SSR (G3TA-OD) is
mounted, terminals 0 to 15 will be posi-
tive.
