6.2.3 VLT ®
Resolver Option MCB 103
The MCB 103 option enables connection of a resolver to
provide speed feedback from the motor.
•
Primary voltage: 2–8 V
•
Primary frequency: 2.0–15 kHz
•
Primary maximum current: 50 mA rms
•
Secondary input voltage: 4 V
•
Spring-loaded connection
6.2.4 VLT ®
Relay Card MCB 105
®
The VLT Relay Card MCB 105 extends relay functions with
3 more relay outputs.
•
Protects control cable connection.
•
Spring-loaded control wire connection.
Maximum switch rate (rated load/minimum load)
6 minutes -1 /20 s -1 .
Maximum terminal load
AC-1 resistive load: 240 V AC, 2 A.
6.2.5 VLT ®
Safe PLC Interface Option
MCB 108
The MCB 108 option provides a safety input based on a
single-pole 24 V DC input. For most applications, this input
provides a way to implement safety in a cost-effective way.
For applications that work with more advanced products
like Safety PLC and light curtains, the fail-safe PLC interface
enables the connection of a 2-wire safety link. The PLC
Interface allows the fail-safe PLC to interrupt on the plus or
the minus link without interfering with the sense signal of
the fail-safe PLC.
6.2.6 VLT ®
PTC Thermistor Card MCB 112
The MCB 112 option provides extra motor monitoring
compared to the built-in ETR function and thermistor
terminal.
•
Protects the motor from overheating.
•
ATEX-approved for use with Ex-d and Ex-e motors
(EX-e only FC 302).
•
Uses Safe Torque Off function, which is approved
in accordance with SIL 2 IEC 61508.

6.2.7 VLT ®
Sensor Input Option MCB 114
®
The VLT Sensor Input Option MCB 114 protects the motor
from being overheated by monitoring the temperature of
motor bearings and windings.
•
3 self-detecting sensor inputs for 2 or 3-wire
PT100/PT1000 sensors.
•
1 extra analog input 4–20 mA.
6.2.8 VLT ®
Safety Option MCB 150 and
MCB 151
MCB 150 and MCB 151 options expand the Safe Torque Off
functions, which are integrated in a standard VLT
AutomationDrive FC 302. Use the Safe Stop 1 (SS1)
function to perform a controlled stop before removing
torque. Use the Safety-Limited Speed (SLS) function to
monitor whether a specified speed is exceeded.
These options can be used up to PL d according to ISO
13849-1 and SIL 2 according to IEC 61508.
•
Extra standard-compliant safety functions.
•
Replacement of external safety equipment.
•
Reduced space requirements.
•
2 safe programmable inputs.
•
1 safe output (for T37).
•
Easier machine certification.
•
Drive can be powered continuously.
•
Safe LCP copy.
•
Dynamic commissioning report.
•
TTL (MCB 150) or HTL (MCB 151) encoder as
speed feedback.
6.2.9 VLT ®
Safety Option MCB 152
The MCB 152 option activates Safe Torque Off via the
®
PROFIsafe fieldbus with VLT
option. It improves flexibility by connecting safety devices
within a plant.
The safety functions of the MCB 152 are implemented
according to EN IEC 61800-5-2. The MCB 152 supports
PROFIsafe functionality to activate integrated safety
®
functions of the VLT AutomationDrive FC 302 from any
PROFIsafe host, up to Safety Integrity Level SIL 2 according
to EN IEC 61508 and EN IEC 62061, and Performance Level
PL d, Category 3 according to EN ISO 13849-1.
•
PROFIsafe device (with MCA 120).
•
Replacement of external safety equipment.
