I/O Block Details
3 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, 12). Use
a low-noise power source.
3 OUTPUT BLOCKS
G7TC-OC16(-1)
G7TC-OC08(-1)
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.
Output Block model 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.

To Increase the Number of Outputs
Use sockets (order separately) to increase the number of outputs or to use SPDT I/O Relays on the G7TC.
3 EXTERNAL CONNECTION EXAMPLE
The following is an application example for the P7TF-05 using a SPDT Relay on a terminal of the G7TC-16(-1).
*Use the G77-S Output Short-Circuit Module in
place of the G7T I/O Relay. With the G77-S
voltage output is available between terminals 15
and C15. The maximum current is determined
according to the controller.
Note: If more than one G77-S Output Short-Circuit Module is employed, the voltage output of the terminals on the G7TC
is as follows:
G7TC-OS16: The positive side (the lower row) connects to the common line internally.
G7TC-OS16-1: The negative side (the upper row) connects to the common line internally.
3 P7TF-05 SOCKET
The G7T Relays (SPST-NO, SPST-NC, and SPDT types) and the G3TA I/O Relays can be mounted on the P7TF-05 Socket.
To add SPDT relays (G7T-112S) to a G7TC or P7TF installation, use the G77-S Output Short-Circuit Module and the P7TF-05 Socket.

case
Rails are generally used to mount Relay I/O Blocks. For screw
mounting, a 210-mm DIN rail is available that can be used as an
adapter in combination with End Plates (PFP-M, two required).
3 USING A SHORTING BAR
A Shorting Bar is provided to connect four terminals. The current
capacity of the shorting bar is 20 A. As long as this current
capacity is not exceeded, the shorting bar can be used in
combination as shown at the right to connect more than four
terminals.
Both Input and Output Blocks do not have internal power
supplies. For an Output Block, supply the relay drive power to the
positive and negative terminals (either 12 or 24 VDC). Loads
(terminal contacts 0 through 15) must also be supplied with
appropriate power. For an Input Block, supply power to the
positive and negative terminals for the input signals to the
controller.
The same Connecting Cable, G79-Y, is used for the G7TC-OC08
eight-point Output Block as for other I/O Blocks; leave 8 points
unconnected.
LEDs indicate the presence or absence of signals. Use the
display lever inside each relay for fault diagnosis. (Some relays
do not have this lever, depending on the specifications.)
Each relay must be pressed down until its hold-down hooks
engage completely. Heating or malfunction can result if relays are
not mounted properly.
Unlabeled terminals are not electrically connected. Use these for
repeater terminals.
LED positions and relay orientation differ between Input and
Output Blocks. This is to aid in differentiating Input Blocks from
Output Blocks and in following signal flow. DC I/O Blocks have
positive and negative terminals, with the positive terminals
normally on the top of the I/O Block. Reversing positive and
negative terminals will prevent operation.
20
Operational errors can result if connectors are connected or removed with power supplied to the I/O Block.
