Automated Logic Corporation Z540 Control Module

Automated Logic Z540 Control Module is a compact Z-Line zone control module from Automated Logic Corporation, designed for zone-level management within commercial building automation systems. The unit’s footprint measures 6.3 in by 7.3 in by 1.0 in and it weighs about 1 lb, making it suitable for installation in standard equipment racks or electrical closets alongside other BAS hardware. It runs on 24 VAC power and carries a current rating shown as 0.33 A to 1 A, with compatibility with 50/60 Hz electrical supplies, reflecting the module’s role as a simple, low-power control interface within legacy Automated Logic systems. The Z540 is commonly encountered in surplus or refurbished inventories and has been discontinued by the manufacturer, so new production is no longer available and users typically explore replacement options within Automated Logic's current product families. Despite its age, the Z540 remains part of the historical Z-Line ecosystem, serving as a small, dedicated control point in zoned HVAC installations where space and power constraints are considerations.
