BE1_50_IOC
Basler-shaped instantaneous / definite-time overcurrent high-set (ANSI 50) with dropout ratio and a sealed trip.
When to use it
Use BE1_50_IOC when a high-set element is needed to clear close-in faults without waiting for the inverse-time curve — typically set at 6 to 10 times nominal so it sees only faults inside the protected section.

Supervised control write
BE1_50_IOC commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.

Download BE1_50_IOC — free
Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
