Siemens 6DS1300-8AB Monitor Keyboard Interface Module for SICOMP C30/C35 Systems

Product Overview

The 6DS1300-8AB​ is a Siemens proprietary Monitor and Keyboard Interface Module engineered exclusively for the SICOMP C30 and SICOMP C35 industrial computer platforms, a family of rack-based process control systems widely deployed in European glass, chemical, power, and heavy-process plants from the late 1980s through the early 2000s. Unlike generic PC graphics cards or USB keyboard adapters, the 6DS1300-8AB​ is a backplane-bus-driven module that plugs directly into a dedicated SICOMP rack slot, drawing +5 V and +12 V DC from the backplane and communicating with the SICOMP CPU through native SICOMP bus protocols. Its primary role is to bridge the SICOMP host’s video framebuffer and keyboard scan logic to the cabinet-front HMI peripherals—specifically Siemens SICOMP-compatible CRT/LCD monitors and industrial membrane or mechanical keyboards—over shielded cabling up to 15 meters.In the automation hierarchy, the 6DS1300-8AB​ sits at the operator-interface layer of a SICOMP C30/C35 node. The C30/C35 architecture itself was Siemens’ answer to Unix/VME-based process computing before SIMATIC PC-based solutions took over, and the 6DS1300-8AB was the designated “video + keyboard” slot card, meaning a C30/C35 rack cannot present a local console without it. For plants still running legacy SICOMP lines—float glass control, batch chemical DCS front-ends, turbine-local operator stations—the module is a single-point-enabler for local diagnostics, parameter viewing, and manual intervention. With the platform long obsolete from the Siemens active catalog, the 6DS1300-8AB​ now trades almost entirely in the secondary/spare-parts market, where authenticity, backplane compatibility, and signal cleanliness matter more than datasheet headline specs.The module’s industrial design emphasizes noise immunity: the SICOMP video path carries synchronized RGB/HV signals through the rack backplane onto shielded pigtail cabling, while the keyboard side handles matrix scanning with debounce logic tuned to industrial EMI environments. This makes the 6DS1300-8AB less about “high resolution” (it targets standard SICOMP CRT resolutions of the era) and more about rock-stable console presence shift after shift, year after year, behind a closed cabinet door.
