Product Description

The PSM-ME-RS232 / RS485-P is a communication module designed by Phoenix Contact for converting between RS232 and RS485 communication protocols. This module provides a reliable interface for serial communication in industrial environments, allowing seamless data transmission between devices that use different communication standards. The PSM-ME-RS232 / RS485-P is typically used in applications where devices or systems need to communicate using these widely adopted serial standards.

Technical Specifications

• Input/Output Ports:
• RS232 Port:
• Standard DB9 or DB25 connector for RS232 communication.
• Supports typical RS232 signals (TX, RX, RTS, CTS, DTR, DSR, DCD, GND).
• RS485 Port:
• Typically uses a 2-wire or 4-wire RS485 interface (depending on the model), supporting both half-duplex and full-duplex communication modes.
• Differential signal transmission for robust data transfer over longer distances.
• Protocol Conversion:
• Converts RS232 to RS485 and vice versa, enabling communication between devices that support different serial communication standards.
• Data Rate:
• Supports baud rates from 300 bps to 115200 bps (depending on the specific configuration).
• Signal Isolation:
• Galvanic isolation of up to 2500 V between the RS232 and RS485 sides, ensuring protection from electrical noise and transients.
• Power Supply:
• Typically powered by 24 V DC (nominal), though the specific power supply may vary depending on the model.
• Power Consumption: Typically < 1 W, making it energy-efficient.
• Temperature Range:
• Operating Temperature: -25°C to +70°C (suitable for industrial applications).
• Storage Temperature: -40°C to +85°C.
• Enclosure Rating:
• IP20 rating, suitable for use in indoor environments, typically within a control panel or enclosure.
• Mounting:
• DIN Rail Mountable (35 mm DIN rail).
• Dimensions:
• Typically 90 mm x 22.5 mm x 105 mm (Width x Height x Depth) for a compact form factor.
• Status Indicators:
• LED indicators for Power, RS232 communication status, and RS485 communication activity.
• Connectors:
• RS232: Typically DB9 or DB25 connectors (depending on the model and version).
• RS485: Typically uses screw terminal blocks or sub-D connectors for RS485 wiring.
• Compliance:
• The module is typically CE, UL, and CSA certified, ensuring compliance with relevant safety and electromagnetic compatibility standards.
