PLCs, Power Supplies & Others

The Yokogawa ACM11 provides a dedicated serial communication link for the CENTUM DCS. This module supports the RS-232C protocol for point-to-point data exchange. It connects external devices like host computers or programming tools directly to the controller.

Furthermore, this unit offloads communication tasks from the main processor. Consequently, it ensures stable system performance and deterministic data flow. The Yokogawa ACM11 is a standard choice for integrating legacy serial equipment.

Technical Specifications

Manufacturers often pair this module with advanced trip units like the RMS-TSG-TZ-C Static Trip for comprehensive monitoring . However, the primary function of the Yokogawa ACM11 remains industrial data acquisition.

Hardware & Interface Details

The Yokogawa ACM11 requires installation in a dedicated Communication Module Nest. It utilizes a Dsub 25-pin female connector for physical wiring. You must use specific cables like the KB3 or AKB141 for modem connections.

Additionally, the module supports ASCII or binary transmission codes. It features configurable parity checks including none, odd, or even. However, please note that “no parity” is unavailable at 19200 bps .

Installation & Energy Use

Engineers find the Yokogawa ACM11 easy to deploy due to its compact form factor. The module draws a steady 1.0 A from a 5.0 V DC supply. It does not contain large internal energy storage capacitors, making it safe for hot-swapping in most racks.

Moreover, the operating temperature range supports standard indoor industrial environments. For heavy vibration settings, ensure the module locks securely into the nest slot.
