I/O modules

The DS200AAHAH1AED routes network traffic between multiple Mark V controllers. This board functions as a central hub for Arcnet LAN communications. It forwards data packets across four separate BNC 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. DS200AAHAH1AED weighs just 0.68 kg for straightforward installation. You will find 86 discrete components on a four-layer PCB with ground planes.

Moreover, the board integrates a 220 µF bulk capacitor for energy storage. This capacitor filters high-frequency 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 automatically. Furthermore, LED indicators show link status and data activity for each individual port.

Signal Isolation and Protection Features

Optical isolators provide 1500V AC isolation between each port and the backplane. This design prevents ground loops from disrupting network communications between cabinets. Terminating resistors sit near each BNC connector for proper impedance matching. Consequently, the board maintains signal integrity over longer cable runs up to 300 meters.

Typical Application Scenarios

You can deploy DS200AAHAH1AED in gas turbine control networks with multiple drive cabinets. It also works well for steam turbine systems requiring distributed I/O communication across a plant floor. This board links the main controller to remote I/O panels and operator stations effectively. Its 2.5 Mbps data rate handles real-time control traffic without bottlenecks.
