• The VLT® AutomationDrive FC 302 provides a safety input based on a single pole 24 V DC input
• For the majority of applications this input enables the user to implement safety in a cost-effective way. For applications that work with more advanced products like Safety PLC and light curtains, the Safe PLC interface enables the connection of a two-wire safety link
• The Safe PLC Interface allows the Safe PLC to interrupt on the plus or the minus link without interfering the sense signal of the Safe PLC

• This analog input/output option is easily fitted in the frequency converter for upgrading to advanced performance and control using the additional I/O
• Upgrades the frequency converter with a battery back-up supply for the frequency converter built-in clock (that typically lasts for 10 years, depending on the environment). This provides stable use of all frequency converter clock functions as timed actions
• 3 analog inputs, each configurable as both voltage and temperature input
• Connection of 0–10 V analog signals as well as PT1000 and NI1000 temperature inputs

• ATEX-approved for use with Ex d and Ex e motors (EX e only FC 302)
• Uses Safe Stop function, which is approved in accordance with SIL 2 IEC 61508

• Protects the motor from being overheated by monitoring the temperature of bearings and windings in the motor
• Three self-detecting sensor inputs for 2 or 3 wire PT100/PT1000 sensors
• One additional analog input 4–20 mA

• Facilitates failure analysis with advanced data-logging functionality
• Supports preventive and predictive maintenance features
• Adds time and date stamps to events
• Contains a back-up battery
• Easy to mount

The VLT® Safety Option MCB 151 extended with the VLT® Sensorless Safety MCB 159 option provides safe sensorless speed functions (SS1/SLS/SMS) for VLT® AutomationDrive FC 302.

With the MCB 159 option, an external sensor is no longer required for safe speed monitoring.
Select VLT® Sensorless Safety MCB 159 as a C1 option in the configurator when ordering a new drive.
MCB 159 is not available for retrofit.

MCB 159 is only available as an extension to MCB 151.
