Industrial PM4-SG-DC-4E-ARRR Panel Mount Display Controller

PM4-SG-DC-4E-ARRR is Amalgamated Instrument Co’s panel‑mount display/controller designed for 4‑wire strain‑gauge inputs such as load cells, delivering precise display and control in industrial measurement setups. It features a 4‑digit LCD display option (PM4‑SG family also offers 4‑ or 6‑digit LCD variants) and, in its base configuration, includes a Form A relay; the -ARRR option adds extra relay outputs and a dedicated output board that provides analog retransmission via 4–20 mA, 0–1 V, or 0–10 V plus digital retransmission through an NPN output and an isolated DC supply. The unit mounts in a 48 mm x 96 mm bezel, requires a 45 mm x 92 mm panel cutout, uses plug‑in screw terminals, and weighs about 400 g. PM4‑SG variants support flexible power supplies (factory‑configured) with options for AC and DC inputs, enabling compatibility with common industrial installations.
