Industrial W674B93 Pneumatic Logic Controller Module

Industrial W674B93 Pneumatic Logic Controller Module is a Ross Controls Logicair component designed to deliver compact pneumatic logic within a Ross 27 Series valve network, acting as the logic element that sequences and gates air signals directly at the manifold rather than relying on external electronics. The W674B93 designation is an orderable model within the 27 Series family of poppet valves and adaptors, indicating it is a factory-specified module intended to be used with compatible Ross valves for integrated logic control. Ross documentation for the 27 Series notes the use of EEZ-ON adaptors, which provide an adjustable, gradual pressure buildup at startup, and L-O-X adaptors, which offer lockable shut-off and downstream exhaust, placing logic control options at the valve level when used with Logicair modules. Typical applications include automated sequencing, interlocking, and simple logic control in manufacturing and packaging lines where space, wiring reduction, and air-operated logic are advantageous; when paired with the correct Ross components, the W674B93 can simplify installation and maintenance of pneumatic logic circuits.
