New safety modules are dual microprocessors

摘要

New safety module families from Banner Eng. Corp. are dual micro-processors, each operating with a different instruction firmware set. One of the new families, ES-UA/VA-5A, features four immediate output-switching channels for connection to power interrupt circuits, as well as an auxiliary nonsafety, normally closed output for status monitoring. They are designed to monitor a one-channel or two-channel circuit.
