AutomationDirect ZL-RTB-DB15 Feedthrough Communication Module

The AutomationDirect ZIPLink ZL-RTB-DB15 is a DIN‑rail mounted feedthrough communication module that converts field wiring from a 16‑position screw terminal block to a 15‑pin DB15 D‑sub interface, enabling straight‑through wiring for reliable signal routing in industrial automation systems. Designed for use in PLC systems and control panels, it provides a clean interface between terminal blocks and DB15 ports, simplifying installation, retrofit, or troubleshooting when connecting drives, HMIs, or legacy devices. Its feedthrough design maps each terminal block position directly to the corresponding DB15 pin, aiding diagnostics and reducing wiring mistakes. Key specs include a current rating of ~1 A per circuit and a voltage rating of ~30 VDC, with a wire range of 12–24 AWG, and mounting on DIN rails. Operating temperature ranges from 0 to 60°C, making it suitable for typical factory environments. The ZIPLink ZL-RTB-DB15 is manufactured by AutomationDirect, combining a compact interface with straightforward field-to-port connectivity for PLC communication and signal interfacing in industrial automation setups.
