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. Specifications Contact resistance 10 mΩ max.

I/O Terminal label I/O Terminal indicators Output Block (DC) Yellow Green Transparent Input Bl k Block DC Red Green Green AC Red Red Red Block type I/O Relay 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.
