Product Overview

The Hayward HLIOEXPAND OmniLogic I/O Expansion Board is a genuine Hayward expansion module designed to increase the input and output capacity of compatible OmniLogic pool and spa automation systems.

The board plugs directly into the OmniLogic base unit and adds 4 valve actuator outputs, 4 low-voltage dry-contact relay outputs, and 4 temperature sensor inputs. It is ideal for larger or more complex automation installations requiring additional valves, sensors, or low-voltage equipment control.

Key Features

4 Additional Valve Actuator Outputs
Adds four connections for compatible pool and spa valve actuators.

4 Low-Voltage Relay Outputs
Provides four additional dry-contact outputs for controlling compatible low-voltage pool and backyard equipment.

4 Temperature Sensor Inputs
Adds four inputs for compatible Hayward 10K-ohm thermistor temperature sensors.

Direct OmniLogic Integration
Plugs directly into the OmniLogic base unit and is automatically detected by the automation system after installation.

Configurable Through OmniLogic
Added valves, low-voltage outputs, and temperature sensors can be configured through the OmniLogic Configuration Wizard.

Benefits

• Expands existing OmniLogic automation capacity
• Adds 4 valve actuator connections
• Adds 4 low-voltage dry-contact outputs
• Adds 4 temperature sensor inputs
• Ideal for complex pool and spa equipment installations
• Integrates directly with existing OmniLogic controls
• Automatically recognized by the OmniLogic system
• Allows automation expansion without replacing the complete control panel
• Genuine Hayward replacement and expansion component

Specifications

Installation Information

The HLIOEXPAND installs directly into the compatible OmniLogic base unit. Electrical power to the automation system should be disconnected before opening the control panel or installing the expansion board.

After the board is installed and power is restored, OmniLogic automatically detects the expansion module. The four valve outputs, four low-voltage outputs, and four temperature sensor inputs can then be configured through the system's Configuration Wizard.

Use only compatible Hayward 10K-ohm thermistor-type temperature sensors. Sensors and valve actuators are not included unless specifically stated.

Professional installation by a qualified pool automation technician is recommended.

Confirm Before Ordering

Hayward HLIOEXPAND provides:

• 4 additional valve actuator outputs
• 4 additional low-voltage dry-contact outputs
• 4 additional temperature sensor inputs
• Direct OmniLogic base-unit connection
• Automatic system detection
• Genuine Hayward expansion-board construction

Do not confuse HLIOEXPAND with HLEXPAND.

The HLIOEXPAND is a compact I/O expansion board. The HLEXPAND is a separate full-size OmniLogic expansion panel designed for additional high-voltage relays, breakers, valves, and other equipment.

Warranty Information

Hayward currently lists the HLIOEXPAND with a 1-year parts warranty. Warranty eligibility and coverage are subject to Hayward's current terms, installation requirements, proof of purchase, and applicable exclusions.

Customer Q&A

Q: What does the Hayward HLIOEXPAND add?
It adds four valve actuator outputs, four low-voltage relay outputs, and four temperature sensor inputs to a compatible OmniLogic system.

Q: Does this add high-voltage equipment relays?
No. The four additional relays are low-voltage dry-contact outputs. For additional high-voltage relay and breaker capacity, a different OmniLogic expansion solution is required.

Q: Are temperature sensors included?
No. Compatible Hayward 10K-ohm thermistor sensors are sold separately unless specifically stated.

Q: Does OmniLogic automatically recognize the board?
Yes. Once properly installed, the OmniLogic system detects the HLIOEXPAND during startup and makes the additional inputs and outputs available for configuration.

Q: Is this the same as the HLEXPAND expansion panel?
No. HLIOEXPAND is an I/O circuit board. HLEXPAND is a larger expansion panel with additional equipment-control capacity.
