Max. current flow: 20 A 10 G7TC G7TC G7TC I/O Block Details Input Blocks G7TC-ID16 G7TC-IA16 Input Relay (G7T-1122S) 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. Input Terminal (P7TF-IS16) 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. Connecting Cable: G79-IC- Tape Color: Red DC for the ID16; AC for the IA16. Use at the rated voltage for the G7TC. Independent Common Possible. (Differ in models.) Output Block G7TC-OC16(-1) G7TC-OC08 Output Terminal (P7TF-OS16) 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 lownoise power source. Output Relay (G7T-1112S) 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. Connecting Cable: G79-OC- Tape Color: Yellow 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. (Differ in models.) When an I/O SSR (G3TA-OD) is mounted, terminals 0 to 15 will be positive. 11 G7TC G7TC Connection Example for SPDT Relays The following is an application example for the P7TF-05 using an SPDT Relay on a terminal of the G7TC-16(-1). 24 VDC or 12 VDC Note: 12 (Differ in models.) * 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. 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. G7TC G7TC P7TF-05 Socket The G7T (SPST-NO, SPST-NC, and SPDT types) and the G3TA I/O Relays can be mounted on the P7TF-05 Socket. The P7TF-05 can be used for applications involving sequences that require slim relays, or to enable use of SPDT relays with the I/O Block. To use part of the I/O Block with SPDT specifications, insert an Output Short-Circuit Module into the I/O Block, and use the P7TF-05 Socket in combination with an SPDT Relay for the Module’s output.

Or, order and combine a P7FT I/O Terminal and I/O SSRs. *3 The P7TF I/O Terminal provides only sockets. It does not have Relays mounter to it. Mount I/O Relays or I/O SSRs to the sockets. Specify the rated voltage in the same way as when ordering the G7TC I/O Relay Terminal. • Combinations of AC Input Relays/SSRs and DC Input Relays/SSRs cannot be used with the same Terminal. This is because specifications for coil surge suppression elements are different. Relays/SSRs with different voltage specifications cannot be used with the same Terminal. (For example, a 100-VAC Input Relay and a 200-VAC Input Relay, or a 12-VDC Output Relay and a 24-VDC Output Relay cannot be used with the same Terminal.) This is because specifications of operation indicator circuits are different. • Only use I/O Terminals, I/O Relays, and I/O SSRs with the same specifications for rated voltage. • General I/O Blocks are color coded, as shown below, according to input/output and AC/DC specifications. I/O Terminal label I/O Terminal indicators Output Block (DC) Yellow Green Transparent Input p Bl k Block DC Red Green Green AC Red Red Red • I/O Relay case 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, to the positive and negative terminals, power for 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. • Indicators indicate the presence or absence of signals. • DIN tracks are generally used to mount I/O Blocks. For screw mounting, a 210-mm DIN track is available that can be used as an adapter in combination with End Plates (PFP-M, two required). • 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. • Special Connecting Cables are provided for connections to OMRON SYSMAC I/O Units with Connectors. Connecting Cables with two connectors, however, come in two types: Cables for Input Blocks (G79-I) and Cables for Output Blocks (G79-O). Be sure to purchase the correct Cable for the application. 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. • Indicator 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 Input Blocks and Output Blocks with G3TA-OD have positive and negative terminals, with the positive terminals normally being on the top of the I/O Block. Reversing positive and negative terminals will prevent operation. 16 G7TC G7TC Microload Switching Input Relays (DC coil type) and I/O SSRs (DC input type) can be mounted onto an Output Block. Doing so enables using controller programming to simultaneously switch on or off two outputs (DPSTNO operation) to switch a SPST-NO load that in turn switches another SPST-NO load. One configuration for this is shown below.
