Outputs 1 and 2 are normally open form A relay outputs.
Output 3 is a form C relay output with one normally open and
one normally closed contact. When the output is energized,
both contacts change state. When ordering the C445 Motor
Management Relay, one of the options is to obtain a Base
Control Module where Output 3 is either a standard form C
relay output or a latching form C relay output.

Chapter 3—Installation and Wiring
Output 3 operation as a standard form C relay output means
the output will de-energize and return the contacts to their
normal state when the Base Control Module is powered off.
Output 3 operation as a latching relay output offers capability
beyond what's available from a non-latching, or a standard
relay output. The energized state of the latching relay can be
maintained after power has been removed from the Base
Control Module. Energized means that the normally open
contact will be closed and the normally closed contact
will be open.
There are two additional configuration parameter for the
latching relay and that involves the Power-down behavior.
The following are the four choices for this behavior. These
parameter can be configured using the Power Xpert
inControl Software or via a Modbus message from a Modbus
master. These parameters are called:
Base Control Module Relay 3 Behavior (Modbus register 719):
Behave like a non-latching relay (default) (Modbus value = 0)
●
Behave like a latching relay (Modbus value = 1)
●
If "Behave like a latching relay" is selected for the parameter
above, then the following options are available in the
Output 3 Latching Relay Behavior at Power Down parameter
(Modbus register 729):
Turn Off (default) (Modbus value = 0)
●
Turn On (Modbus value = 1
●
Hold Last State (Modbus value = 2)
●
Toggle (Modbus value = 3)
●
The four bits in the Base Control Module Field Output
Control word (Modbus register 601) can be assigned in any
order to control the various outputs as follows:
Output 1 Function Select: Select Field Output Control
●
Word bit 0, 1, 2 or 3
Output 2 Function Select: Select Field Output Control
●
Word bit 0, 1, 2 or 3
Output 3 Function Select: Select Field Output Control
●
Word bit 0, 1, 2 or 3
Output 3 Reset Function Select: Select Field Output
●
Control Word bit 0, 1, 2 or 3 (for Latching Relay
Operation only)

register map.
