CB1 Alarm Operation
The CB1 alarm circuitry (ALRM_M contact) in the 2094-ALxxS, 2094-BLxxS,
and 2094-XL75S-Cx line interface modules is closed only when CB1 trips
(meaning input current exceeds instantaneous current trip setting) and not
dependant on the ON/OFF switch. The ALRM_B contact is closed when CB1
is manually set to the ON or OFF position, and open when CB1 is tripped.

Description
Line contactor coil connections with an auxiliary contact from the control power circuit
breaker wired in series with the contactor coil. The line contactor is a safety contactor that
includes three main contacts with four auxiliary contacts (see figure on
Four pairs of auxiliary contacts that are normally-closed on the line contactor (see figure
on page 21).
Power supply capable of supplying 24V @ 6 A for I/O functions and switches. Each set of
pins is capable of 2 A. To use the full rating of the supply, all pins must be used to provide
the appropriate current rating (see figure on
