Safety analog input, four channels
The 1SAP482000R0001 hosts four 4-20 mA analog inputs with 14-bit resolution, rated for use in SIL2 and SIL3 safety loops. The module is part of the ABB AI581 series, designed for safety-instrumented functions that require a clean, isolated current loop reading.
IP20 housing keeps dust out, not water—mount inside a panel. Ambient operating range from -30 to +70°C covers most process environments, including unheated outdoor cabinets. Power is 24 VDC; no backplane or slot dependency—this is a distributed I/O module wired directly to the controller.
