Hyundai STVF5 STVF7 OPB-340 Car Communication Board

The Hyundai OPB-340 Board is an electronic PCB installed inside the car operating panel of Hyundai STVF5 and STVF7 elevator systems. It supports car call input and communication between the operating panel and related elevator components.

Inside the Car Operating Panel

Unlike a main controller or display board, the OPB-340 works directly with functions inside the elevator car operating panel.

In STVF7 applications, the board is used for car call input, key box connection, LS board connection and related COP signals. This makes it an important board when troubleshooting button or operating-panel communication problems.

OPB-340 boards may carry identification markings such as 280C288H11, 280C288H12 or 280C288H13, depending on the version.

When Sourcing a Replacement

The OPB-340 model should be checked together with its hardware number and connector layout.

Useful information includes:

• Elevator system: STVF5 or STVF7

• Board model: OPB-340

• Complete 280C288 hardware number

• Front and rear PCB photos

• Connector positions

• Related car operating panel photo

• Required quantity

If the existing board carries an H11, H12 or H13 suffix, include that marking when requesting a quotation. Similar OPB-340 versions should not automatically be treated as interchangeable.
