Siemens SIMATIC S7-300 analog I/O module SM 334 (order 6ES7334-0CE01-0AA0) provides four analog inputs and two analog outputs. The module is non-isolated from the backplane and uses a 20-pin interface that allows removal/insertion with the active backplane bus. Each channel delivers 8-bit conversion, making it suitable for interfacing analog sensors and actuators within a SIMATIC S7-300 automation system.
