Description

The Siemens 6ES7336-4GE00-0AB0 SIMATIC S7-300 SM 336 is a high-performance, fail-safe analog input module designed for safety-critical process automation. As part of the SIMATIC S7-300 and ET 200M distributed I/O systems, this module provides reliable signal acquisition for applications requiring high functional safety, including SIL 3 (IEC 61508) compliance. It features six analog input channels specifically designed for 0/4–20 mA current signals, supporting both 2-wire and 4-wire transmitter configurations.

Features

• Fail-safe analog inputs for safety-instrumented systems (SIS).
• 6 isolated analog input channels.
• 15-bit resolution plus sign (up to 16-bit with overrange).
• Native HART protocol support for bidirectional communication, remote configuration, and diagnostics.
• Reverse polarity protection for the 24V DC supply.
• Supports SIL 3, Category 4, and PL e safety standards.

Applications

• Chemical and petrochemical plants for reactor pressure and temperature monitoring.
• Oil and gas refinery safety systems.
• Power plant burner management and steam control systems.
• Industrial safety monitoring in automotive paint shops and hazardous zones.
• Automated logistics and crane load monitoring.

Technical Specifications

Installation Guidelines

• Mounting: Hook the module onto the S7-300 DIN rail and swing it into place. Secure it using the integrated mounting screw.
• Bus Connection: Ensure the U-shaped bus connector is securely seated in the backplane to establish communication with the CPU or adjacent modules.
• Wiring: Use a 20-pin front connector for field wiring. Always use shielded cables for analog signals to minimize EMI interference.
• Grounding: Utilize a shielding bracket to ground cable shields as close to the module as possible.
• Safety: Ensure power is disconnected before installing or removing the module from the rack.
