PSM-ME-RS232/RS232-P Serial Isolator
For the electrical isolation of RS-232 (V.24) interfaces, the PSM-ME-RS232/RS232-P is the ideal solution.
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. Using the PSM-ME-RS232/RS232-P Serial Isolator, considerably higher immunity to interference in industrial applications can be achieved.
By isolating the TX/RX data channels and the RTS/CTS control lines the PSM-ME-RS232 Serial Isolator effectively protects your RS232 devices from transient surges, lightning strikes, ground loops and noise issues.
