Line Interface Module 19
Contactor Coil
For safety reasons, the internal wiring is arranged so that if the control power
(CPL) circuit breaker (CB2) trips, the opening contact will interrupt the coil
voltage and remove main input power to the drive.
The 2094-AL

line interface modules use
an AC coil and a DC interface module allows the contactor coil to be controlled
by the 24V DC output of the drive. Additional surge suppression is not required
for these contactors.

The contactors in the 2094-AL09 and 2094-BL02 line interface modules use a
DC coil. The contactor coil voltage is 24V DC with a suitably-rated surge
suppressor fitted inside the line interface module.
