Transio A52/53
The Transio A52 and A53 are smart RS-232 to RS-422/485 bi-directional converters that come with all of the great technical specs that Moxa is known for. This includes data direction control built into the hardware for both the RS-422 and RS-485 interfaces, LED indicators for power and signal states, and surge protection and isolation protection. The last two features take care of some of the major problems faced by serial communication connections in industrial environments.
Serial Connection Problems in Industrial Environments
Serial communication and reliability can be adversely affected in a hazardous industrial environment. The wiring associated with serial communication devices could be surrounded by power lines, motors, or equipment that produces static electricity. If this is the case, the serial devices could be damaged by sudden surge waves produced by this type of equipment. In this situation, surge protection that uses TVSS (Transient Voltage Surge Supression) is the solution.
When two serial devices are directly connected, but separated by a long distance, the unbalanced ground voltage could cause serious damage. Unbalanced ground voltage between two serial ports forms a “ground loop,” introducing a large current between the two pieces of serial equipment. In fact, the current could be so lare as to damage the equipment beyond repair. In this situation, the solution is to use isolation protection to provide complete isolation for both communication ports.
What is Surge Protection?
Surges are high amplitude pulses that last only a few millionths of a second in duration. They can be caused by heavy-duty equipment, power lines, short circuits, or large motors. A surge suppressor has the ability to absorb the high energy instantly and effectively to prevent the connected devices from being damaged.
What is Isolation Protection?
Electrical isolation is achieved by using a photo coupler to transform an electric signal into light, and then retransform the light back into an electric signal on the other side of the isolator. In this way, the two electric circuits are completely isolated from each other.
ADAM-4562
ADAM-4561/4562 allows PC users to connect a serial device to a system that use a USB interface. To attach the ADAM-4561/4562 to a PC, you don’t need to open the chassis or power down your PC. Instantly get one or two extra high-speed RS-232/422/485 ports. The power is derived from the USB port, so there are no power adapters to deal with. Thismakes the ADAM-4561/4562 especially suitable for modems, printers, POS systems and industrial control devices.
Compliant with USB V1.1, ADAM-4561/4562 features several powerful functions such as high-speed 115.2 kbps transmission, support for various operating systems, independentRS-232/422/485 ports and more. By simply plugging in a USB hub, ADAM-4561/4562 eliminates the configuration issues associated with high-priced, older card solutions. Youonly have to install the drivers, no need to set cards slots, IRQ addresses, DMA channels, or device addresses. This reduces programming effort.
TCC-82
The TCC-82 provides full electrical isolation for bi-directional serial communication between two RS-232 devices in a compact, industrial-grade package. Both sides of an RS-232 connection are isolated optically to provide perfect protection against lightning surges, accidental high voltage shorts, and ground loops. The built-in, wide range isolators are tested to ensure that they can withstand more than 4 kV rms input to output for 1 minute. This means that the TCC-82 not only meets the requirements of general serial data communications, but also the high standards required by industrial automation and medical applications. The TCC-82 protects the TxD and RxD data lines, and also protects the RTS and CTS handshake lines for a total of 4 isolated channels to provide complete protection of your RS-232 applications.
External Power Source Not Required
The TCC-82 supports port-powered operation, which means that it can obtain power directly from the attached serial devices. Power is obtained from the RS-232 TxD, RTS, or DTR lines, regardless of whether the signal is high or low, eliminating the need for an external power supply. However, external power can be used if handshake lines are not available, if the serial cable is too long, or if the serial device is a low powered device. For external power, the TCC-82 can use a 5 to 12 VDC adaptor or a USB power cord. Note that both sides of the connection are powered independently, so if necessary, one side can rely on port power and the other on an external power source.
When installing the TCC-82, we recommend that you connect all output signals. The TCC-82 obtains power from these signals even if they are not used by your system. Care should be taken when choosing the external power supply if your application requires the full 4 kV of isolation. Most commercial power supplies provide only 1500 VAC isolation between the primary and secondary windings. If you are using external power for both sides of the TCC-82, make sure that separate power sources are used, each with sufficient isolation protection.
