Modbus RTU repeater | power supply 24 VDC | surface mounting
Product description
This is a 24 VDC power supply with built-in Modbus RTU repeater. The switching power supply offers protection against short circuit, overload and overvoltage.
The maximum load is 900 mA or 20 W. Both 24 VDC channels are galvanically separated. The load can be connected via PoM - both 24 VDC and Modbus RTU communication are connected via an RJ45 connector.
The Modbus RTU communication of the two channels is reinforced by the built-in half-duplex line repeater. The supply voltage is in the range of 85 to 264 VAC (50-60 Hz).
The enclosure can be surface mounted and offers an IP30 protection against ingress of dust.
Additional specifications and description
24 VDC power supply module
This 24 VDC switch mode power supply is a reliable source of power with a comprehensive array of protective features. This power supply not only provides a stable 24 VDC output but also incorporates safeguards against potential disruptions. Its protective functions include short-circuit protection, overload protection and overvoltage protection.
The overload protection feature serves as a safeguard against damage resulting from an overcurrent of the load. In the event of a short circuit, the power supply responds by temporarily shutting down until the fault condition is resolved. The overvoltage protection ensures that excessive voltage is never applied to the load, even when dealing with unstable input voltages. These protective mechanisms make our 24 VDC switch mode power supply a dependable choice for a wide range of applications.
Modbus RTU repeater
Our PDM-8-MB goes beyond being just a power supply. It is also a galvanically isolated, half-duplex line repeater designed to enhance Modbus RTU communication. This device is ideal for interconnecting various Sentera devices and strengthening Modbus RTU communication. It is particularly useful in scenarios where long cable lengths and significant distances separate different Sentera devices, ensuring that communication remains stable and unaffected.
For instance, in applications where the distance between Sentera devices becomes so extensive that communication is prone to disruption, the PDM-8-MB comes to the rescue. It guarantees a stable Modbus communication, even when dealing with extended cable lengths.
Universally applicable
One of the standout features of this device is its universality. With a wide supply voltage range (85 - 264 VAC, 50 / 60 Hz), it seamlessly integrates into a multitude of applications, ensuring compatibility and flexibility.
In terms of connectivity, the PDM-8-MB makes it easy. The load can be effortlessly connected via PoM (Power over Modbus) through an RJ45 connector. In fact, PDM-8-MB offers two RJ45 sockets, streamlining the connection process.
An RJ45 socket, also known as an RJ45 jack or connector, serves as a standardized physical interface employed for establishing connections between Ethernet cables and various network devices. This connector type is widely recognized and utilized in both residential and commercial settings, making it the predominant choice for Ethernet connections. Furthermore, it adheres to the established standard when connecting Sentera's Power over Modbus RTU devices.
Freestanding or surface-mounted installation options
When it comes to installation, the enclosure is designed for both surface mounting or it can be a freestanding device. It provides an IP30 rating for protection against dust and dirt. This means that you can trust it to maintain optimal performance even in less-than-ideal environmental conditions. The enclosure is encapsulate din order to protect the internal components.
The material used is PC/ABS - composite material made by blending polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS). This combination results in a material that combines the strengths and properties of both PC and ABS, the resulting material inherits the best attributes of both components. It offers good impact resistance, heat resistance, and dimensional stability, making it suitable for electronics. The enclosure
Whether you are looking for a reliable power supply or a solution to bolster your Modbus communication, the PDM-8-MB is a dependable choice.
