Using the OMP-MODL 2-8
Terminal Strip Connections
The MLCPU-1 is provided with a terminal strip connector for connection of
power, input and output wiring (Figure 2... -4). The terminal strip connector
can be unplugged from the module allowing for quick disconnect and
reconnection of wiring. Connection details follow:
External Power (Terminals 1 & 2)
An external power source may be used to power the OMP-MODL .
If an external power supply is connected to the OMP-MODL and its
supply voltage is greater than approximately 10.7 VDC, the OMP-
MODL will operate from the external supply and the batteries will not
be used. In the event that the external power fails or drops below
10.7V, the OMP-MODL will automatically transfer to battery power
and continue operation.
The External Power Supply terminals will accept either AC or DC
input and polarity is not relevant.
E XTERNAL S UPPLY V OLTAGE R ANGE :
A field selectable dual input range feature allows the logger to
accomodate a very wide range of input voltage applied to the
External terminals. A jumper provided on the MLCPU-1
programs the input range for HI or LO range:
LO Range: (8 to 24 Vdc / 10 to 23 Vac) (factory default)
HI Range: (11 to 32 Vdc / 12 to 23 Vac)
