Moore Industries introduces the new universal SLD PC-Programmable Functional Safety Loop Display. The SLD features a large integral display that shows real-time process status in mA, percent, or any designated 5-character Engineering units (EGU). As part of Moore Industries’ FS Functional Safety Series products, the SLD is certified by exida as a SIL3 capable, non-interfering device for use in a safety loop.
