FEATURES
The CBCSM1, used in conjunction with the CSM1 Current Sense Module (sold separately), will
sense the AC Power State of a component and pass a control voltage to another components
Control Input or voltage controlled device. This allows the CSM1 to operate as a
general purpose
current sensor instead of being used exclusively with an MRC44 or MRC88 Controller. The
CBCSM1 will provide Positive or Negative logic on its Pull UP or Pull DOWN terminal
connections.
NOTE:
Requires CSM1 Current Sense Module and 781RG Power Supply both sold separately.
CSM Input:
Interfaces with the 3.5mm Stereo Mini plug of the CSM1 Current Sense Module. The
CSM1 detects the Power State of the component and passes a ‘sense’ voltage to the CBCSM1
Connecting Block.
PULL UP:
This output will pass a 12vDC voltage whenever the CSM1 detects a power ON state
(Green threshold LED ON). When the CSM1 detects a power OFF state (Green threshold LED
OFF), the PULL UP terminal will be switched to GND (0v). See
Table 1
.
PULL DOWN:
This output will be directly opposite of the PULL UP terminal. The PULL DOWN
terminal is switched to GND (0v) whenever the CSM1 detects a power ON state and will pass
12vDC whenever the CSM1 detects a power OFF state. See
Table 1
below.

HARDWARE CONNECTIONS
1. Plug the CSM1 (shown in Figure 2) into an unswitched AC Power Source.
2. Plug the 3.5mm stereo mini plug from the CSM1 into the jack labeled
CSM Input
on the
CBCSM1 Current Sensor Connecting Block.
3. Connect a 12v Power Supply to the 2.1mm Coaxial Power jack on the CBCSM1
4. Interface the desired logic output of the CBCSM1 (Pull Down or Pull Up) to the controlled
source as in
Figure 3.
