I/O Relay Module Racks - 70MRCK16-RS

The 70MRCK16-RS I/O relay module rack provides reliable switching and signal transmission capabilities for a variety of industrial and commercial applications. It utilizes 8 module bays to accommodate different kinds of I/O relay or signal modules, including logic inputs, contact inputs, FET outputs, relay outputs, contact outputs, and other specialized types. The module bays are arranged in two groups of 4, with each group associated with a separate base plate. This allows users to customize the system configuration for different applications.

Features

The 70MRCK16-RS features a wide range of features that make it an ideal solution in many commercial and industrial applications. The unit is certified to EN 60079-0 and carries an ATEX Directive II 2 G Ex db IIC T5 rating. The rack is made of robust steel construction with a corrosion-resistant powder-coat finish, and it is designed to be dust and moisture resistant. The module bays feature rubber or rubber-like side walls to ensure proper contact and protection for the module life, and recessed PCB lids increase installation safety. An adjustable latch prevents accidental opening of the module rack door. The base plate is designed to minimize vibration, and the system also includes a removable side panel for easy access.

Applications

The 70MRCK16-RS is an ideal choice for automation projects, sensor and valve control, switch controls, signal transmission, and other applications requiring reliable switching and signal transmission. The rack system is highly versatile and can be used in a wide range of environments, including hazardous areas. The system meets the IP65 dust and water jet protection criteria and can operate in temperatures ranging from -20°C to +45°C. It is also certified to carry out safety-related operations in potentially explosive environments.

Working Principle

The 70MRCK16-RS operates on a simple yet effective working principle. The signal transmission is controlled by a central, electromechanical element, known as a relay. The relay energizes the connected loads and controls their output in response to a set of logic signals. A set of electrical contacts connected to the relay open or close when the relay is energized, allowing or preventing the flow of electricity depending on the signal signals.

The system also features multiple circuit modules that provide additional functionality and flexibility. These modules can provide additional inputs and outputs, signal conditioning, logic function, and other features. The modules can also be used to provide feedback on the status of the connected loads.

The 70MRCK16-RS enables users to customize the system configuration for their specific application, while ensuring a reliable switching and signal transmission. The system is easy to install and requires minimal maintenance, making it an ideal choice for many applications.
