Safety Instrumented System SIS Analog Input Module SM336

1Overview of Safety Instrumented System SIS Analog Input Module SM336

Safety Instrumented System SIS Analog Input Module SM336, SIMATIC S7, Analog Input SM 336, 6 AE; 15 Bit； Fault safety type analog input terminal for SIMATIC Safety, with support for HART protocol, up to Class 4 wire (EN 954-1)/SIL3 (IEC61508)/PLE (ISO13849), one 20 pin, order number: 6ES7336-4GE00-0AB0.

The Safety Instrumented System SIS Analog Input Module SM336 can be used together with IM 153-2 HF in ET 200M distributed I/O devices, or is centrally used for the characteristics of SIMATIC S7-31xF-2 DP, SM 336; F-AI 6 x 0/4 - 20 mA HART； 6 analog inputs, with electrical isolation between the channel and backplane bus, input range: 0 to 20 mA 
, 4 to 20 mA. Short circuit protection power can be provided from 2-wire or 4-wire transmitters through the module. External encoder power can be used, and it can be used in safe mode. HART communication, firmware update data recognition through HW Config.
