Overview• 4-channel loop control module for universal closed-loop control tasks
• Used for temperature, pressure, flowrate and fill-level control loops
• User-friendly online self-optim ization for temperature controls
• Preprogrammed controller structures
• 2 control algorithms
• 2 versions:
- FM 355 C as continuous-action controller;
- FM 355 S as step or pulse controller
• With 4 analog outputs (FM 355 C) or 8 digital outputs (FM 355 S) for direct control of the most common types of actuator
• Continued operation of the contro l loop is possible even after a CPU stop or failure
