The 33SARL is a red LED indicator block designed for use in empty LBX control stations with screw terminal connections. It operates at 12/24 Vac/Vdc and is base-mounted for secure installation in control station assemblies. The block features standard LED signaling functionality with two connection terminals (X1 and X2) for reliable electrical integration. This component is commonly used in industrial control applications where visual status indication is required, providing clear red illumination for operator feedback in machinery and process control systems.
