The PSM-ME-RS232/RS485-P rail-mountable andcompact interface converters have been designedespecially for industrial use in the switch cabinet orswitch box. They convert the RS-232 interface signalsbidirectionally to the RS-485 2-/4-wire and RS-422standard.The devices are simply snapped onto standard ENmounting rails and supplied with 24 V DC or AC.Their particular feature is the multifunctionalapplication:– RS-232 master interface in RS-485 bus systems– Networking RS-232 equipment– RS-232 range increase to 1000 m as interferencefree and fast point-to-point connection– RS-232 interface adaptation to RS-422 and RS-485systemsThe following features of the interface converter areparticularly outstanding:– 3 operating modi can be configured- RS-232 ↔ RS-485-2-wire- RS-232 ↔ RS-485-4-wire- RS-232 ↔ RS-422– Can be used universally in all common bus systemswith UART/NRZ data format and 10/11 bits characterlength– Transmission rate can be set between 4.8 kbit/s and115.2 Mbit/s– Automatic transmit/receive changeover– High-quality 3-way isolation(VCC // RS-232 // RS-485)– Integrated surge voltage protection with transientdischarge to the mounting rail– Supply voltage of 24 V DC or AC to suit the switchcabinet– Minimal current consumption/power dissipationHeadquarters: © Phoenix Contact GmbH & Co.

Sample applications1.1.1. RS-232 // RS-485 interface converterThe RS-485 standard is specified for applicationswith multipoint connections. We distinguish between2-wire bus systems with half-duplex transmission and4-wire bus systems with full-duplex transmission:– RS-232 master adaptation (fig. 2a)– Programming /and parameterizing connection(fig. 2a)– Networking RS-232 stations (the software mustguarantee that the stations can be addressed;(fig. 2b)1.1.2. RS-232 // RS-422 interface converterThe RS-422 interface is a balanced to earth interfacefor point-to-point connections. The logical states arerepresented by a differential voltage between two lines.Areas of application are:– Interface adaptation to RS-422 devices(fig. 3a).– Interference-free and fast point-to-point connectionup to 1000 m (fig. 3b)
