SEC402-51 S1 is a Yokogawa esb bus coupler module engineered for the Yokogawa ProSafe-RS safety system. It performs the documented esb bus coupler module function within the Yokogawa ProSafe-RS hardware architecture, so the complete order code, hardware execution and receiving position must be retained during selection.
Product-level and manufacturer-family information records bus function: ESB bus coupling; node role: Safety node communication interface; network family: ESB bus. Before replacement, compare the installed label, rack or carrier, terminal or connector arrangement, power and signal requirements and approved configuration; after installation, verify diagnostics and every affected control, communication, safety or monitoring path before returning the equipment to service.
The SEC402-51 S1 ESB Bus Coupler Module is supplied only after the exact hardware identity, condition and current OEM lifecycle status have been confirmed.

SEC402-51 S1 is a Yokogawa esb bus coupler module engineered for the Yokogawa ProSafe-RS safety system. It performs the documented esb bus coupler module function within the Yokogawa ProSafe-RS hardware architecture, so the complete order code, hardware execution and receiving position must be retained during selection.
The listed parameters are limited to the documented model or product-family evidence. Compare the complete label, receiving hardware, terminal map and connected equipment rather than transferring ratings from a nearby code.
SEC402-51 S1 must remain matched to the documented Yokogawa ProSafe-RS safety system installation. Confirm hardware generation, slot or carrier, connector or terminal arrangement, software or configuration dependencies and system drawings before approval.
Photograph labels and connections before removal and preserve the original position, keying, addressing and channel allocation.
Isolate the equipment using the approved procedure, verify stored energy is removed and inspect the receiving hardware before fitting SEC402-51 S1.
After installation, restore power in the documented sequence, review diagnostics and test every affected signal, relay, network, control, safety or monitoring function against the commissioning record.
