Siemens Modules 6ES7241-1CH32-0XB0

The Siemens 6ES7241-1CH32-0XB0 Communication Module (CM 1241) is an expansion module for the SIMATIC S7-1200 series of Programmable Logic Controllers (PLC).

Specification:

• Module Type: Communication Module (CM 1241).
• Compatibility: Used with SIMATIC S7-1200 CPUs.
• Interface: A single RS-422/RS-485 channel via a 9-pole D-Sub (female) connector.
• Supported Protocols: Supports various industrial protocols, including Freeport (message-based), Modbus RTU (Master/Slave), ASCII (via library functions), 3964(R), and USS (via library functions).
• Supply Voltage: 24 V DC (permissible range 20.4 – 28.8 V DC).
• Power Consumption: Typical power loss of approximately 1.1 W.
• Communication Distance: Capable of communication over a maximum distance of 1,000 meters (depending on the baud rate).
• Isolation: Features 707 V DC electrical isolation between the RS-485 signals, chassis, and CPU logic for protection against transient voltages.
• Diagnostics: Equipped with LED indicators on the front panel for connection status and quick troubleshooting.
• Design: Compact dimensions of 30mm (width) x 100mm (height) x 75mm (depth).
• Installation: Snaps directly onto the DIN rail next to the CPU, connecting mechanically and electrically via an integral slide mechanism, saving space and preparation time.
