Description

Product Overview

The ARND‑3119A (alternate drawing code 5D3A1118P031) is an isolated signal conditioning / interface PCB for TMEIC high‑power drive systems, evolved from legacy Toshiba industrial control hardware. It provides galvanic isolation, analog signal conversion and fault monitoring between the main drive controller and field transducers, encoders, tension / speed feedback devices. It is commonly fitted inside TMdrive‑10 and TCM master control racks for steel rolling mills, large paper machine drives and heavy industrial main motor control. This “A” revision is the signal interface version; the A6 variant (ARND‑3119 A6 / 2N3A3119‑B) is the separate redundant generator AVR board, not the same PCB.
