I/O Relay Modules

I/O relay modules are types of electronic relay modules that are frequently used when performing circuit switching duties. The most popular type of I/O relay module is the 70-OAC5A-L. This module is specifically designed to provide galvanic insulation between the sensor and the output, allowing for sensing in hazardous areas and operations requiring electrical isolation.

Application Field and Working Principle of 70-OAC5A-L

70-OAC5A-L I/O relay module is equipped with two optically isolated input channels, each of which can be connected to a separate sensor. The inputs can be configured to be either normally open (NO) or normally closed (NC). When the inputs are in the normally open (NO) configuration, pulse signals generated by the sensors can be read and the relays can be activated when the pulse signal is generated. When the inputs are in the normally closed (NC) configuration, the relays are activated when the sensor detects an object.

In addition, 70-OAC5A-L modules have two output channels-A and B-that can be connected to different types of nodes. Output A is equipped with a normally open (NO) contact which is suitable for controlling electric, pneumatic, and hydraulic equipment. Output B is equipped with normally closed (NC) contacts, which can be used to trigger operations on safety-critical nodes such as shut-off valves or emergency stop switches.

The 70-OAC5A-L I/O relay module is designed to tolerate a wide range of voltage. It also includes surge and overvoltage protection, making it highly reliable. The module is also UL recognized, meaning that it is suitable for use in industrial applications where safety and reliability are paramount.

The use of the 70-OAC5A-L I/O relay module is not limited to industrial applications. It can be used to control electrical and pneumatic equipment in a variety of applications, such as robotics, medical devices, agricultural equipment, and aviation. It can also be used to provide control signals to machines in automated production lines.

In summary, the 70-OAC5A-L is an ideal solution for controlling equipment in hazardous or isolated environments. Its ability to operate reliably in a wide range of voltage and its surge and overvoltage protection make it an ideal choice for any application that requires reliable operation and safety.
