Multifunction relay 2W, for ETR4-70-A potential 031888

Multifunction relay ETR4-70-A is an advanced device suitable for both industrial installations and commercial or residential buildings. Designed by Eaton, it offers a wide range of timing functions, enabling precise control of various electrical circuits. Its compact dimensions (width 23 mm, height 83 mm, depth 103 mm) allow for easy mounting on a TH rail, which greatly simplifies installation and servicing.

The device is characterized by its versatility thanks to the possibility of powering it with both AC and DC voltage in the range of 24-240V. The relay has two instantaneous switching outputs and two delayed switching outputs, providing flexibility in circuit configuration. The rated operating current is 3A, making it suitable for controlling various loads.

Functionality and Application

ETR4-70-A is a multifunction relay, which means it offers a number of operating modes. The ability to choose from functions such as delayed switching on and off, pulse generation, flashing with different edge settings, and timing with adjustable time, allows you to adapt the device to specific application needs. The time setting range from 0.05 seconds to 360000 seconds (100 hours) ensures precision in controlling timing processes. Remote control capability further expands the range of relay applications.

Thanks to the wide range of control voltages (24-240V AC/DC) and high resistance to interference (compliance with IEC/EN 61812-1 and other standards), this relay guarantees reliable operation even in harsh industrial conditions. Made of high-quality materials and with a protection class of IP20, it ensures durability and safety of use. The relay is adapted for mounting in any position according to installation requirements.

Construction and Mounting

The ETR4-70-A relay has screw connections, which simplifies the connection of wires. The lack of the need for an additional socket simplifies installation and reduces installation costs. The device is designed for mounting on a TH rail, which is a standard in most electrical switchboards. The mechanical durability of 30 million operations (AC/DC control) guarantees a long service life even with intensive use.
