Product Features
YOKOGAWA SEC401-51 is responsible for data flow forwarding and protocol conversion between the safety control unit and the safety node unit.
YOKOGAWA SEC401-51 can connect up to 9 units (including Safety Node Unit SNB10D and Optical Repeater Module SNT4XX, e.g. SNT401, SNT411, SNT421) to support I/O channel expansion of the safety instrumented system.
YOKOGAWA SEC401-51 can be fixedly mounted in slots 7 and 8 of the safety control units, ensuring compatibility with the system and structural stability.
YOKOGAWA SEC401-51 can differentiate the explosion-proof characteristics by suffix code (-E with explosion-proof function, -5 without explosion-proof function) and supports ISA standard G3 (suffix code with “1”), adapting to scenarios with different safety levels.
Product Using Principle
YOKOGAWA SEC401-51 can receive the control commands from the safety control unit and forward them to the connected safety node unit; meanwhile, it will transmit the field data collected by the node unit back to the safety control unit, with a transmission speed of 128 Mbps to ensure real-time performance.
YOKOGAWA SEC401-51 carries out address allocation and communication scheduling for the nine connected units to avoid data conflicts and support distributed I/O expansion.
Connecting the node units through the ESB bus cable, the maximum transmission distance is 10m, which is suitable for high-density node layout within a short distance; if you need to extend the distance, it can be combined with the optical repeater module SNT4XX.
Product Applications
YOKOGAWA SEC401-51 can be used in safety instrumented systems (SIS) in the petroleum, chemical, natural gas and other process industries for connecting safety control units to field safety nodes.
YOKOGAWA SEC401-51 can be used in hazardous environments (e.g. production halls with flammable and explosive substances) that are explosion-proof or comply with ISA standard G3.
YOKOGAWA SEC401-51 can be used in safety control stations with extended I/O channels for large-scale data acquisition and control by connecting several SNB10D node units.
