Evolution Aqua Contactor AC230V/DC24V - Auxillary relay

The Evolution Aqua GR8-208 is a compact DIN-rail mounted auxiliary (intermediate) relay designed to switch higher-current loads from low-power control signals. It provides electrical isolation between control and power circuits and is commonly used in automation, filtration, pumping, and control panel applications.

Key Features

• Supply voltage: AC 230V (A1–A2) or AC/DC 24V (A1–A3)
• Frequency: 50/60Hz
• Output contacts: 2 × SPDT (two changeover contacts)
• Contact rating: 2 × 8A (AC1)
• Switching voltage: Up to 250VAC / 24VDC
• LED status indication for relay operation
• Compact 1-module DIN rail design
• Fast switching response with approximately 40 ms changeover time
• Suitable for signal amplification and load switching in control systems.

Typical Applications

• Pond and aquarium control systems
• Pump and motor control
• UV and filtration equipment switching
• Building management systems
• HVAC controls
• Industrial automation panels
• PLC output isolation and signal expansion.

Technical Summary

Product Description

The GR8-208 auxiliary relay is used to increase switching capacity, duplicate control contacts, and isolate control circuits from power circuits. When energized by either a 230V AC or 24V AC/DC control signal, the relay switches two independent changeover contacts, allowing multiple devices or higher-current loads to be controlled safely from a single control output. Its slim DIN-rail format and LED indication make it ideal for control cabinets and automation installations.
