2.3.6 Wiring a Bulk DC Power Supply to the PSSM
Caution
At this time you can also connect power and watchdog wiring.
However; for safety reasons and to prevent accidental damage to the
your bulk DC power supply, do not connect the pluggable terminal
block connectors TB1 and TB2 to the PSSM until after you install, wire,
and configure the CPU module.
Follow the instructions in Section 2.3.5 General Wiring Guidelines when
wiring connections.
You can connect one bulk DC power supply (nominally either +12 Vdc
or +24 Vdc) to the PSSM. The PSSM then converts, regulates, and
filters the power to +3.3 Vdc. For safety, the PSSM circuit has a 3A
fuse.
The ControlWave Micro PSSM’s operating range is +10.7 to +30.0 Vdc
(with nominal +12Vdc input source) or +21.7 to +30.0 Vdc (with a
nominal +24Vdc input source).
Use the following formula to determine the maximum current required
for the +12 Vdc or +24 Vdc bulk power used with a particular
ControlWave Micro:
Bulk + 12/24 Vdc Supply Current = CPU* + Sum of all ECOM modules and I/O modules.
Refer to Table 2-2 for ControlWave Micro bulk power requirements.
