Red Lion Controls IMP23100 Process Controller

Red Lion Controls IMP23100 is a panel‑mount, 4½‑digit DC intelligent meter for process inputs in the IMP Apollo family, designed to display and monitor process signals for weighing and automation applications. It is described as a process meter (not a full controller) within Red Lion’s IMP/APOLLO line, and distributors list the unit as discontinued by the manufacturer, with an approximate weight of 0.60 kg. The IMP23160 is the replacement model in the same family and is advertised as replacing IMP23100, adding excitation and switch outputs with 115/230 VAC operation. This device sits in Red Lion’s IMP Series Apollo Intelligent Meters for Process Inputs, offering compact, panel‑mount readout of a process signal in a single instrument.
