Overview of the Yokogawa ACP71 Profibus Communication Card

The ACP71 works as a Profibus communication card within Yokogawa’s distributed control platforms. This card links controllers to Profibus DP networks for fast field device communication. Engineers deploy it in process plants that demand dependable, high-speed data exchange.

Key Technical Specifications of the ACP71

The ACP71 pairs a compact card body with a dedicated Profibus connector. Below you will find the core parameters that define this card’s performance envelope.

Physical Design and Interface Details

The ACP71 adopts a compact footprint that fits standard Yokogawa I/O racks. Its dimensions measure 130 mm in length, 100 mm in width, and 25 mm in depth. Moreover, the card weighs roughly 220 grams, which simplifies rack installation and field replacement. The 9-pin D-sub connector accepts standard Profibus cabling directly.

Performance and Communication Capabilities

This card supports Profibus DP at transfer rates reaching 12 Mbps. Bus-to-logic isolation shields internal circuitry from electrical noise, therefore protecting sensitive components. Additionally, the card handles deterministic cyclic data exchange with remote field devices. Consequently, the unit suits high-availability process control architectures.

Power and Environmental Considerations

The ACP71 operates on a 24 V DC nominal power supply. Power consumption remains approximately 3 W during normal operation. The operating temperature range spans 0°C to 55°C for industrial environments. Storage temperature extends from -20°C to 70°C. Furthermore, humidity tolerance reaches 95% RH without condensation.
