Mornsun Power Distribution and Transceivers

Modern IoT drives industry digitization, intelligence, and integration. This emphasizes server-to-server information flow.

App developers must consider many transmission mechanisms. For example, RS485 and CAN bus are standard wired data technologies. Signal reception in noisy environments and great distances is their main purpose.

This article compares the two communication channels.

CAN, an automotive bus standard, allows microcontrollers and devices to communicate without a host computer. It’s a message-based system designed to reduce copper use in car electrical wiring but has many other uses. Several traits define it.

It offers a high real-time performance rate and a dependable transmission thanks to its industrial field bus that corresponds to an international standard.

Second, 10 km transmission at 1 MHz bps is achievable.

There is no restriction on the number of nodes that can be added to a network that uses a single bus, which is currently at 110.

Multiple masters and equal nodes are popular and regional networks are easy to set up.

RS-485 defines a point-to-point network’s electrical interface and physical layer. For example, RS-485 allows multiple devices to share a bus and long wire runs, even in noisy environments. These are their main traits.

“1” represents a +(2-6)V differential between lines. The line voltage differential is -(2-6)V. RS-232-C has a better signal-to-noise ratio. Thus, the interface circuit chip is durable. TTL circuits can easily connect to the level.

RS-485’s balanced driver and differential receiver reduce noise. Multiple stations can communicate over long distances. This serial connection is usually ideal.

Both communication channels require transceiver circuitry. Electrical engineers developing power systems may benefit from Mornsun’s experience. However, due to our 23 years of power supply experience, we can provide high-quality transceivers like Mornsun CAN/RS485/RS232 modules.

Mornsun‘s most current chip-scale packages SOIC isolated Bus transceivers are the TDA51S-41HC and TDA51SCANHC (R5 BUS IC). Both lines operate from -40 degrees Celsius to +125 degrees Celsius and have an I/O voltage range of 4.5V to 5.5V. R5 BUS ICs have isolation voltages up to 5000Vrms and CMTIs up to 150kV/us. These transceiver modules can send 1Mhz CAN bus signals to 100 nodes in a millisecond with a 5V supply voltage.
