Ross Controls D1523A4102 Energy Isolation Device

The Ross Controls D1523A4102 Energy Isolation Device is a pneumatic lockout valve engineered to isolate a machine's energy source for safe maintenance and controlled startup. Belonging to the Ross L-O-X 15-Series family of energy isolation valves, it provides local machine-level lockout functionality and is designed to support OSHA 29 CFR 1910.147 and related standards for energy isolation devices. Rated for 2 to 10 bar operating pressure, this device is intended for pneumatic circuits where energy release must be prevented during service. Internal reference number #147621 helps identify the unit in documentation and ordering; the product is visually identifiable by the yellow body used to distinguish energy isolation devices in the Ross L-O-X family. Used during maintenance to safeguard personnel and equipment, the D1523A4102 enables compliant lockout/tagout procedures and reliable re-energization when work is complete. Within the 15-Series lineup, the D1523A4102 encodes a specific sub-family, port size, and configuration, allowing selection to match a machine’s physical footprint and exhaust requirements. Because it is a L-O-X energy isolation device, it should be installed at the point of energy source to prevent accidental re-energization.
