TXD2SA-4.5V

The TXD2SA-4.5V signal relay is a two-pole signal relay module used in various control systems. This selection of signal relays covers a wide range of applications from basic on/off circuits up to 2 Amps of continuous current. The module is designed in a Through-Hole Through package and provides signal isolation from two primary circuits.

Applications

The TXD2SA-4.5V signal relay is commonly used in industrial applications such as actuators and motor controls. It can also be used in complex control systems where two input signals need to be isolated and fed to a single output. It is also used in home automation systems for controlling devices such as lights, fans, and water pumps.

Design Features

The TXD2SA-4.5V signal relay is designed for general-purpose applications in the industrial and commercial markets. It has an operating temperature range of -40˚F to 257˚F(-40˚C to 125˚C). The modules have a highly reliable plunger and electro-mechanical coil construction and provide automatic thermal protection. It also has an operating life of >100,000 cycles. The relays are packaged in an 8-pin DIP package that has an operating voltage of 4.5V to 16.8V and a switching current of 2 Amp.

Working Principle

The working principle behind the TXD2SA-4.5V signal relay is the actuation of a plunger when an electromagnet is energized, or de-energized. When the electromagnet is energized, it attracts the plunger towards it, thus actuating or engaging the relay. The plunger is connected to a contact which completes the circuit when the plunger is engaged. When the electromagnet is de-energized, the plunger is released, and the contact is opened, thus breaking the circuit.
