6ES7355-2CH00-0AE0 Siemens SIMATIC S7-300 Temperature Control Unit FM 355-2 C Original Brand New

• 4-channel closed-loop controller module specifically for temperature controls
• Including integrated and easy-to-use online self-optimization
• Heating and cooling controllers as well as combined controllers with heating and active cooling function feasible
• Ready-to-use controller structures
• 2 versions:
  • FM 355-2 C as a continuous controller;
  • FM 355-2 S as step or pulse controllers
• With 4 analog outputs (FM 355-2 C) or 8 digital outputs (FM 355-2 S) to directly control the most common final control elements
• Continuation of control mode also possible with CPU stop or failure

The FM 355-2 closed-loop control module is the intelligent 4-channel temperature control module.

It can be used, for example, in the following sectors:

• General mechanical engineering
• Plant engineering
• Industrial furnaces
• Cooling and heating apparatus
• Food and drinks industry
• Rubber and plastics machines
• Chemical and process industries
• Glass and ceramics industry

The FM 355-2 is available in two versions:

• FM 355-2 C:
  As a continuous controller with 4 analog outputs for driving analog actuators
• FM 355-2 S:
  As step-action or pulse controller with 8 digital outputs for driving motor-driven (integrating) or binary-driven (electric strip-type heaters and cartridges) actuators.

The FM 355-2 can be used in SIMATIC S7-300 and ET 200M with S7-300/-400 as a DP master.

• User-friendly wiring;
  Encoders and actuators are connected via two separate 20-pin front connectors.
• LEDs:
  Red fault LED (group fault);
  green LEDs for indicating the status of the digital inputs;
  yellow LED for indicating backup operation
• High-performance measured data acquisition:
  The module has 4 analog inputs for analog value acquisition and disturbance variable input as well as 1 additional analog input for temperature compensation when used with thermocouples.
• Various encoders can be used:
  Thermocouples, Pt 100, voltage encoders, current encoders.
• Extensive I/O:
  • FM 355-2 C:
    4 analog outputs for analog final control elements;
  • FM 355-2 S:
    8 digital outputs for motorized actuators or binary controlled actuators.
    The 24 V DC supply for the actuators is applied externally.
• Resolution and accuracy:
  The A-to-D conversion has 14-bit resolution and greater accuracy than in the case of FM 355.
  This is an advantage especially when using thermocouples.
