• Small-scale machinery and process automation

When it may not be suitable

This module is specifically designed for use with compatible Zelio Logic smart relays and may not be compatible with other programmable logic controller brands. It is intended for AC voltage applications and should not be used in systems requiring DC-only signal processing or high-speed counter inputs beyond its specified operational limits.

Key specifications

• Digital inputs: 8
• Relay outputs: 6
• AC input voltage: 120-240 V
• Frequency: 50-60 Hz
• Certifications: C-Tick, GOST, CSA, GL, UL
• Weight: 220 g

How to use

The module is installed by connecting it directly to the base Zelio Logic smart relay unit using the provided expansion interface. Ensure that the power supply is disconnected before performing any wiring. Connect your digital sensors to the input terminals and your controlled devices to the relay output terminals according to the wiring diagram provided in the technical documentation. Once connected, the base unit will automatically recognize the extension module, allowing you to configure the additional inputs and outputs within your control software.

What to consider before purchase

• Verify compatibility with your existing Zelio Logic base unit
• Ensure your power supply matches the 120-240 V AC requirement
• Check that the number of inputs and outputs meets your project requirements
• Confirm the physical space available in your control cabinet

Usage recommendations

Always ensure that the total current load on the relay outputs does not exceed the manufacturer's specified limits to prevent damage to the module. Regularly inspect terminal connections to maintain secure contact and prevent signal interference in your automation system.
