Yokogawa ALR121-SE1 Serial Communication Module

Description

The Yokogawa ALR121-SE1 is a serial communication module designed for field control stations (FCS) to interact with subsystems like FA-M3. It enables serial communication and can be mounted on various Yokogawa field control units.

Features

• Serial Communication: Supports RS-232C and RS-422/RS-485 interfaces for both point-to-point and multipoint connections.
• Flexible Communication: Offers half-duplex communication with start-stop synchronization.
• Versatile Data Transfer: Handles ASCII and binary transmission codes with adjustable character and stop bit lengths.
• Error Detection: Supports parity checking (none, even, odd) for data integrity.
• Mounting Options: Compatible with multiple Yokogawa field control units for easy integration.
