TBI1 status interface board - technical overview

The TBI1 Status Interface board is used to create a physical electrical connection from an SLD (Sliding Link Disconnect) terminal block to an IoDT1 Digital Termination board utilizing 5/8” stud spacing. The TBI1 board is primarily used in retrofit RTU applications in which the wiring from monitored status points is terminated to an SLD terminal block. These blocks are mounted inside an enclosure, adjacent to corresponding IoDT1 boards. Manufacturers of this type of terminal block include States and Poweright.
