the JC-MER-CXB
To operate, the JC-MER-CXB requires low-voltage AC or DC power
provided to its four-pin removable keyed connector. Consult the
specifications for power requirements. There are several means for
providing power.
DC Powered
Make connections as shown in the diagram. The unit uses a DC-DC
converter that accepts a wide range of voltage (10–30 VDC) which it
converts for internal use. The “0Vdc” connection is connected to
chassis within the unit. Input connections are reverse-voltage protected.

Redundant DC Powered
Redundant diode-isolated DC power inputs are provided on the unit
when a concern exists that the unit remain operational in the event of
a primary power failure. Make connections as shown in the diagram.
Each power supply must be capable of powering the unit. Do not
assume that input currents from the two supplies will be balanced.
