MCB 114 sensor input module
Fig. 53 MCB 114 sensor input module
The MCB 114 offers three additional analog inputs for
the CUE:
• one analog 0/4-20 mA input for an additional sensor
• two analog Pt100/Pt1000 inputs for temperature
senso
rs.
The three analog inputs are default used for monitoring.
For
further information, see section MCB 114 sensor
input module on page 29.
Scope of delivery
The MCB 114 comes with a terminal cover, an
extend
ed frame and an identification label to put onto
the CUE.

Technical data
All analog inputs are galvanically separated from the
suppl
y voltage (PELV) and other high-voltage termi-
nals.
