Interface Isolator RS-232/RS-232

From Phoneix Contacts, the DIN-Rail mounted PSM-ME-RS232/RS232-P Interface converter is used for electrical isolation of RS-232 interfaces. The robust four-channel converter is a category 3 device designed for installation in zone 2 potentially explosive areas. It meets the requirements of EN 60079-0:2012+A11:2013 and EN 60079-15:2010.

Featuring diagnostic and status indicator LEDs for supply voltage and RS232 data reception and transmission. The PSM-ME-RS232/RS232-P Interface converter offers the user the flexibility to meet the many demands of today’s industrial applications.

Programming

The PSM-ME-RS232/RS232-P signal conditioners are configurable slide switches accessed via opening the housing and sliding out the PCB. TxD and RxD, as well as the RTS and CTS cables, can be crossed internally using a DTE/DCE slide switch so that you are able to conveniently adapt to DTE or DCE interfaces.

Features and Benefits

• DIN Rail Mounting
• The RS-232 connection on the field side can be established conveniently using plug-in screw terminal blocks
• High-quality 3-way isolation up to 2 kV (VCC // RS-232 // RS-232)
• Integrated surge protection with transient discharge to the DIN rail
• Maximum transmission speed of 115.2 kbps
• Transmission of TxD/RxD data channels and RTS/CTS control lines
• 24 V DC or AC power supply suitable for the control cabinet
• Active data transmission indicated by separate data indicators for the transmit and receive channels

Application Example

The RS-232 interface is an asymmetric voltage interface with common signal ground for all signals. In addition to its very low signal power, a characteristic feature of the interface is that the signal ground is connected to the grounded chassis housing. This results in very little immunity to interference and a maximum range of 15 meters. Considerably higher immunity to interference is achieved in industrial applications with the interface converter for electrical isolation.
