Overview

Ing makabukud a safety barrier a maki switch input relay outputs, a mag isolate at mag transmit input signals ibat kareng switch contacts o proximity switches kareng delikadung lugal papunta king safety zone a maki output relay kapamilatan ning safety barrier. Ing line fault detection agawa ya kapamilatan ning LED keng babo ning module. Ing dial switch ning module magagamit ya para i-set ing input ampo output in-phase o reverse control, ampo para i-enable o i-disable ing line fault detection alarm indication function.

Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals.
