Reliance 802820-24RK Analog Input Module

Reliance Electric AutoMax 45C340 analog input module, 8-channel, 4-20 mA, part number 802820-24RK, is a legacy eight-channel analog input board designed for Reliance AutoMax PLC systems. Each of its eight channels accepts a 4-20 mA current-loop signal and converts it to an analog input for the controller, enabling direct integration with common industrial transmitters used in process instrumentation. The module is cataloged as the 45C340 family (8-channel analog input, 4-20 mA) and is also referenced by the J-3048A designation in some listings. Typical applications include monitoring process variables such as flow, pressure, level, and temperature where 4-20 mA transmitters are standard. It is intended for installation in a Reliance AutoMax I/O rack and is commonly paired with other analog or digital I/O modules to form a complete control system. Note that the 45C340/802820-24RK appears in distributor catalogs as a legacy and discontinued module.
