The SB311 S1 is a push-button control station designed for industrial automation and machine control systems. Its primary function is to provide operators with manual control of equipment, allowing start, stop, or emergency shutdown commands to be executed directly on the machine or control panel. The SB311 S1 offers an intuitive and durable interface, ensuring safe and efficient interaction with the machine.
In practical industrial applications, the SB311 S1 can be directly integrated with motor starters, contactors, or PLC input modules, enhancing operational safety and flexibility. It is commonly used in production lines, process control systems, and heavy machinery environments where reliable human-machine interaction is crucial. The device is designed to withstand mechanical stress, vibration, and harsh environmental conditions, providing long-term durability and stable performance.
The SB311 S1 YOKOGAWA ESB bus Interface Master Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The SB311 S1 operates based on mechanical drive and electrical contact switching. When an operator presses the button, the internal contact mechanism closes or opens the circuit, sending a corresponding electrical signal to the connected control system. The motor starter, PLC, or other control device interprets this signal to perform the desired operation, such as starting or stopping the motor. The SB311 S1 enables operators to have safe, reliable, and immediate control over industrial equipment through this simple and reliable contact mechanism.
The SB311-S1 is designed for mission-critical plant environments where accurate sequential tracking of rapidly changing electrical and process events is crucial for safety and post-failure analysis.
1. Event Sequence Recording (SER): This module replaces the standard SB301 module and records changes in digital inputs with a 1-millisecond resolution.
2. Post-Failure Analysis: Engineers can use the data recorded by this module to reconstruct the timeline of plant trips and equipment failures, helping to identify the root causes of "critical failures."
3. Time Synchronization: This module receives high-precision timecode (IRIG-B format) from an external master clock via an RS-422 port, ensuring perfect synchronization of all events recorded in the DCS.
