Relay coupling module 15.8mm, 2P 8A 24VDC, AgNi contacts, screw terminals, DIN 35mm rail mounting 48.52.7.024.0050SMA

Coupling module – reliable switching in automation systems

This coupling module, based on an electromagnetic relay, is a compact solution for controlling circuits with 24VDC voltage. Its design, with a width of only 15.8mm, allows for efficient use of space in control cabinets and switchgear. This module is particularly useful in applications requiring galvanic isolation between the control circuit and the load circuit.

Construction and application

The module consists of a double-pole relay with a load capacity of 8A, equipped with contacts made of silver-nickel alloy (AgNi). This ensures high reliability and durability, even with frequent switching cycles. Screw terminals facilitate wire connection, and the ability to mount on a standard 35mm DIN rail ensures quick and easy installation. The module finds application in building automation, lighting control systems, HVAC, and other industrial applications requiring reliable switching of loads.
