Siemens A01JLDLV U 1 24DC Industrial Relay Module

Siemens A01JLDLV-U is an auxiliary contact accessory designed to mount on JD-LMD molded‑case circuit breakers to provide a dedicated signaling contact without requiring a separate control device. It is part of the JD-LMD auxiliary switch family (with A01JLDLV and A02JLDLV variants) and specifies a switching voltage range of 12 to 24 V DC with a maximum contact load of 0.1 A, making it suitable for simple input signaling rather than power switching. Intended for use with Siemens JD, LD, and LMD frame breakers, this compact accessory enables reliable status feedback to controllers, PLCs, or alarm circuits, supporting interlock logic, fault signaling, and machine safety interlocks in control panels. The A01JLDLV-U version reflects the single‑contact configuration, while the A02JLDLV version provides an additional auxiliary contact, allowing more complex signaling schemes within the same breaker footprint, all designed to preserve compact panel layouts while expanding monitoring capabilities.
