PRL\/1 is an industrial converter, from RS232 serial standard to 400 V-isolated RS485, powered by a low voltage supply. It can be used to allow the communication of devices using two different serial standards, or to isolate two sections of a heavily disturbed serial communication. Thanks to its compact 1-module DIN rail housing, it can be easily mounted in an electrical panel. It accepts a wide range of AC and DC voltages, and it is completely Plug&Play, since it does not need any driver nor DIP switch. RS232 serial is Full Duplex, while the 400 V-isolated RS485 is Half Duplex. The RS232-RS485 serial converter automatically detects data direction and transmission data rate up to 250 kbps, so it can be easily installed in any new or existing network.<\/p>\n

Serial converters are typically used to communicate with old devices and machinery using RS232, and integrate them in a RS485 low voltage network. RS232 serial standard is still common for industrial appliances, but it has limited transmission range and it is vulnerable to electromagnetical noise. Electromagnetical interferences (EMI) are fairly common in industrial environments, so it is good practice not to use RS232 for serial communication to guarantee signal integrity. In case of heavy electromagnetical interferences, a section of optical fiber is recommended. Furthermore, optical fiber guarantees perfect electrical isolation in case of voltage surges or lightnings.<\/p>\n

RS232-RS485 converters are available also without isolation, powered by 230 V, or with DB9 RS232 connector. PRM\/1<\/a> converter for example comes with a non-isolated RS485, in case it was not necessary. IMC\/9R<\/a> (isolated) and RMC\/9R<\/a> are smaller and ideal for direct connection to a device with a DB9 connector. Industrial serial converter PRLP\/1<\/a> is functionally identical to PRL\/1, but it is powered by 230 V mains voltage, like PRMP\/1<\/a>, which in turn is not isolated. Other combinations of serial standard, optical fiber, and power supply, are however available, while special requests (such as higher data rates) can be made via the contact form.<\/p>\n","protected":false},"excerpt":{"rendered":" PRL\/1 is an industrial converter, from RS232 serial standard to 400 V-isolated RS485, powered by a low voltage supply.<\/p>\n It accepts a wide range of AC and DC voltages, and it is completely Plug&Play, since it does not need any driver nor DIP switch.
