The GG2 Display Module is an intrinsically safe apparatus for the purpose of displaying and transmitting sensor data and system information. The GG2 Display consists of a certified GG2 Display Module and associated wiring installed within an IP66 rated stainless steel enclosure. This document details the Modus and iMAC communication protocols.
The Intrinsically Safe Digital Monitor (IDM) provides optical isolation between two separate intrinsically safe Ex ia circuit configurations, or an intrinsically safe circuit to a non-intrinsically safe [Ex ia] circuit configuration. Its digital output switches state when the input signal, a standard 4 to 20mA current input or a 9 to 30VDC voltage input, is above or below a set point configured by the user.
