Product Description

The ACM11-S2 is a high-performance serial communication interface designed for Yokogawa PLC and machine control systems. It enables reliable data exchange between the controller and external serial devices such as barcode scanners, HMIs, and analytical instruments. Supporting the RS-232C standard, it provides a point-to-point communication link essential for integrating legacy equipment into modern automation architectures.

Engineered for industrial reliability, the ACM11-S2 supports data transmission speeds up to 230 Kbps, ensuring low-latency communication for critical process data. Its compact DIN rail design and ultra-low power consumption (<1 W) make it an efficient solution for space-constrained control panels. With a wide operating temperature range, it is suitable for harsh industrial environments requiring stable and continuous operation.

Technical Specifications

Application Context

The ACM11-S2 is commonly used in:

• Factory automation systems

• Pharmaceutical manufacturing

• Chemical processing plants

It is ideal for connecting standalone or legacy devices that require RS-232C communication, such as:

• Weighing scales

• Laboratory instruments

• Specialized sensors and analyzers

This makes it a practical solution for integrating non-networked equipment into centralized control systems for data acquisition and control.

FAQ

Is the ACM11-S2 compatible with multi-drop configurations?
No. RS-232C is a point-to-point communication protocol. For multi-drop or multi-device networking, RS-422 or RS-485 modules are typically required instead.

What type of cable is recommended for 230 Kbps operation?
A high-quality shielded twisted-pair (STP) cable is recommended. Cable length should remain within RS-232C limits (typically under 15 meters) to minimize signal degradation at high transmission speeds.
