Product:Allen Bradley 1746-A10 AB SLC 500™ Modular Chassis 1746-A10 in stock

SLC 500 series A chassis (1746-A4, 1746-A7, 1746-A10, and 1746-A13) manufactured before November 1992 have a resistor between the logic ground and chassis ground as the drawing on the following page illustrates. This resistor could be damaged if the wiring recommendation described within the attention box above is not followed. See the figure on the following page for the location of the resistor. SLC 500 series A chassis (1746-A4, 1746-A7, 1746-A10, and 1746-A13) with a manufacture date of November 1992 or later do not have this resistor. SLC 500 series B chassis have a 1 MΩ resistor that limits the current between logic ground and chassis ground
