Power connector
The 4-pole TYCO power connector is only to be used when interfacing with the RTCU
MX2i pro/pro+. When the PNM interface box is connected to the RTCU CX1 flex/pro the
PNM-200 series device is powered through the RJ45 connector. The PNM interface box
must be supplied between 12...36 VDC from an external DC power source connected to
the PWR connector.
•
Positive power is applied to pin 1.
•
Ground is applied to pin 4.
The PNM interface box is protected against wrong polarity. However if the box is polarized
wrong while the connected RTCU unit is correct polarized, and power is applied, the
internal GND connection will break. For avoidance of such a scenario a fuse can be
installed on the positive supply.
PNM interface connector
This connector includes the power supply, as well as the communication signals to the
PNM device. The PNM device can be connected using the supplied interface cable.
RTCU interface connector
Using this RJ-45 connector the RTCU unit can be connected to the PNM interface box and
control the power to the PNM device. The different kinds of RTCU units have their own
interface cable to the PNM interface box. Please see the section “Typical Application” for
further information.
