Advantech ADAM-3909 DB-9 Terminal Board

Advantech ADAM-3909 DB-9 Wiring Terminal Board is a DIN-rail mounted interface that connects Advantech PC-LabCard I/O modules to field wiring. It carries a single DB9 female connector and a 10-pin screw-terminal block, enabling a DB9 serial signal path to be wired to screw terminals for external devices. As part of the ADAM-3900 family of I/O wiring terminal boards, the ADAM-3909 is designed to be mounted on DIN rails and to interface with PC-LabCard cards, offering a compact DB9-to-terminal wiring solution. This module is described as a DB9 wiring terminal board for DIN-rail mounting that can be connected to PC-LabCard products to expose individual pins for external wiring. Typical applications include bridging a PC-LabCard's serial I/O to sensors, actuators, or other industrial devices in a cabinet or panel, where a DB9 connector on the device side is used for easy mating with common serial cables and a screw-terminal block provides robust field wiring. The ADAM-3909's simple, two-connector design keeps wiring organized in control panels, enabling straightforward pin-level access to a PC-LabCard-based data acquisition or control system within the Advantech ecosystem.
