The PSM-ME-RS232/RS485-P is an interface converter from Phoenix Contact, designed for converting RS-232 (V.24) signals to RS-422 (V.11) or RS-485 standards. It provides electrical isolation between the RS-232, RS-422/RS-485, and power supply, ensuring safe decoupling of potentials. This device supports both 2-wire (half duplex) and 4-wire (full duplex) RS-485 operation, as well as 4-wire RS-422 point-to-point communication.

Key features include:

Transmission Speed: 1.2 kbps to 115.2 kbps.

Power Supply: 18 V AC/DC to 30 V AC/DC (nominal 24 V AC/DC).

Current Consumption: Typical 85 mA at 24 V DC.

Surge Protection: Integrated transient discharge to the DIN rail.

Mounting: DIN rail.

Dimensions: Compact design for industrial use.

Isolation Voltage: 1.5 kV AC between interfaces.
