IO Hvac Controls iO-LL Controller
The IO Hvac Controls iO-LL Controller is a professional-grade 24V lead/lag controller designed for mission-critical redundancy in HVAC and industrial systems. Engineered with a robust microprocessor, this universal lead/lag controller balances operating runtime between two redundant devices, significantly reducing mechanical wear and extending the service life of equipment. The iO-LL is ideal for managing redundant HVAC compressor lead/lag operations, as well as fans, pumps, and motors in commercial or industrial environments.
This controller features true dual-stage control, allowing for seamless alternation. The lead sequence reverses every time 24V power is cycled to terminal 1 for at least 10 seconds. In high-demand scenarios, the iO-LL can energize both units simultaneously when a second-stage signal is provided. With a high 12A contact rating at 24VAC, it handles heavy inductive loads without the need for additional pilot relays in most standard applications. The integrated status LEDs provide instant visual confirmation of power status and active equipment stages, simplifying diagnostic workflows for technicians in the field.
Key Benefits:- Automated Runtime Balancing: Prevents uneven wear by alternating the lead unit every power cycle, ensuring balanced equipment aging.
- High Load Capacity: Features a 12 Amp contact rating, making it compatible with a wide range of motors, pumps, and cooling equipment.
- Flexible Application: Supports both single-stage and dual-stage lead/lag operations for complete system redundancy.
- Simplified Diagnostics: On-board status LEDs allow contractors to identify which standby unit is energized at a glance.
- Compact Integration: The small footprint allows for easy installation inside existing control cabinets or HVAC electrical panels.
How does the lead/lag sequence alternate on the iO-LL?
The alternation is triggered by 24V power cycles. When 24VAC is removed from the input terminal for more than 10 seconds and then reapplied, the microprocessor automatically switches the lead position to the redundant unit.
Can this controller run both units at the same time?
Yes. While its primary function is alternation, the iO-LL supports a dual-stage application. If 24V is applied to the second input terminal while the first is active, the lag unit will energize to meet increased demand.
What are the electrical requirements for the iO-LL?
The unit requires a 24VAC input voltage. It is critical that the controller is powered from the same 24V source as the equipment control circuit to ensure proper signal logic and isolated output performance.
