I/O modules

The DS200AAHAH1ADC manages communication between multiple Mark V controllers. This board acts as a hub for Arcnet LAN network traffic. It routes data packets across four separate ports at 2.5 Mbps.

Key Technical Specifications

Physical Dimensions and Component Layout

This board measures 8.5 cm in length and 13.5 cm in width. Its total height reaches 2.0 cm including all components. DS200AAHAH1ADC weighs just 0.68 kg for straightforward installation. You will find 86 discrete components on a four-layer PCB.

Additionally, the board integrates a 220 µF bulk capacitor for energy storage. This capacitor filters noise on the 24V supply rail. It also provides a 5 ms hold-up time during brief power interruptions.

Network Ports and Signal Routing

The front panel features four BNC coaxial connectors for network cabling. Each port connects to a separate controller node in the Arcnet network. An internal active hub chip forwards packets between all active ports. Furthermore, LED indicators show link status and data activity for each port.

Signal Isolation and Protection

Optical isolators provide 1500V AC isolation between each port and the backplane. This design prevents ground loops from disrupting network communications. Terminating resistors sit near each BNC connector for impedance matching. Consequently, the board maintains signal integrity over longer cable runs.

Typical Application Scenarios

You can deploy DS200AAHAH1ADC in gas turbine control networks with multiple drive cabinets. It also works well for steam turbine systems requiring distributed I/O communication. This board links the main controller to remote I/O panels and operator stations. Its 2.5 Mbps data rate handles real-time control traffic efficiently.
