Ordering number 130B1110 uncoated–130B1210
coated (Class G3/ISA S71.04-1985)
Analog I/O option MCB 109
This analog input/output option is easily fitted in the
adjustable frequency drive for upgrading to advanced
performance and control using the additional inputs/
outputs. This option also upgrades the adjustable
frequency drive with a battery backup supply for the clock
built into the adjustable frequency drive. This provides
stable use of all adjustable frequency drive clock functions
as timed actions.
•
Three 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.
•
3 analog outputs each configurable as 0–10 V
outputs.
•
Included backup supply for the standard clock
function in the adjustable frequency drive. The
backup battery typically lasts for 10 years,
depending on environment. Ordering number
130B1143 uncoated – 130B1243 coated (Class
G3/ISA S71.04-1985).
PTC thermistor card MCB 112
With the MCB 112 PTC thermistor card, all Danfoss
adjustable frequency drives with STO can be used to
supervise motors in potentially explosive atmospheres.
MCB 112 offers superior performance compared to the
built-in ETR function and thermistor terminal.

•
Sensor input card MCB 114
The option protects the motor from being overheated by
monitoring the bearings and windings temperature in the
motor. The limits, as well as the action, are adjustable and
the individual sensor temperature is visible as a read out in
the display or by serial communication bus.

•
Extended cascade controller MCO 101
Easily fitted and upgrades the built-in cascade controller to
operate more pumps and more advanced pump control in
master/slave mode.

Extended relay card MCB 113
The extended relay card MCB 113 adds inputs/outputs to
®
VLT AQUA Drive for increased flexibility.
