Installation relay 24VAC 1NO+1NC 16A ERD218

Installation relay 24VAC – reliable circuit control

The ERD218 installation relay is a compact device designed for remote control of electrical circuits. Rated operating current of 16A and versatility of application – from lighting to heating devices – make it an ideal solution for both home and industrial installations. A construction with one normally open (1NO) and one normally closed (1NC) contact allows for flexible configuration of control circuits.

Construction and application

This relay, occupying only one module width, is widely used in home automation systems, lighting, heating control and all kinds of electrical devices. Manual control via a slider facilitates testing and servicing of installations. 24VAC power supply ensures compatibility with various control systems. The relay is particularly useful where separation of the control circuit from the working circuit is required, which increases the safety and reliability of the entire system.

Key features and benefits

• Versatility: Ability to connect different types of loads – bulbs (up to 1100W), fluorescent lamps (up to 570VA, and with compensation – even up to 1200VA).
• Compact dimensions: A width of only one module makes it easy to mount in switchboards with limited space.
• Manual control: Slider for manual operation allows for quick testing and verification of the relay's operation without the need to connect the control voltage.
• Safety: Protection class IP2X protects against accidental contact and the ingress of solid objects larger than 12.5 mm.
• Flexibility: Possibility of additional equipment expands the functionality of the device and adapts it to the specific needs of the installation.
• Durability: Designed for frequent switching - mechanical endurance is as much as 100,000 cycles, and electrical 30,000 cycles.
• Wire cross-section: Accepts flexible wires with a cross-section from 1 to 6 mm² and rigid from 1 to 10 mm².

The ERD218 relay is characterized by a rated operating voltage of 230V, a rated operating current of 16A and a control voltage of 24V AC. It has one normally open (NO) and one normally closed (NC) contact, and its mounting depth is 60mm.

The ERD218 relay is a solid and reliable solution for professionals and demanding users who value functionality and safety in every element of the electrical installation.
