If you have an application where you wish to use DC power to power a
DIGIMAX
DIGIMAX
DIGIMAX
DIGIMAX

,
you must either use a UPS
or contact
POWER
TEC
for a special unit.
Terminal 6 may be used for small 12VDC loads up to 100 mA.
Terminal 7 can supply up to 50 mA at 20 to 24 VDC, unregulated. Terminal 7 is most
often used to turn on the DIGITAL mode in the Model 1000 series and larger drives (using
the 141-108 series Current Controller board), and this is, in fact, recommended.
The output level of these two terminals is dependent on the AC supply voltage.Other
loads on the unit and the load on each of these terminals will also affect the voltage level.
If either of these terminals are overloaded, the accuracy of the
DIGIMAX

will be degraded.
Terminal 4 or 5 may be used as a common for these terminals.
Voltage levels on terminals 6 and 7 ARE NOT GUARANTEED
. These outputs are
for convenience only for small loads associated with the

If stable and/or
regulated voltages are needed for external relays and devices used for system purposes,
the user should incorporate in the system a separate power supply for them.

+ FREQUENCY OUTPUT
This is the output frequency to the controlled drive or drives. It is capable of driving up
to ten inputs of motor controls or ten other

inputs or a combination of the two
adding up to ten inputs. Output from these terminals is a square wave from a "totem-pole"
driver with a +24 VDC peak and an off value less than 0.5 VDC. The duty cycle may vary.
12
- ANALOG OUTPUT
13
+ ANALOG OUTPUT
The analog output at TB1 terminals 12 and 13 may be used to read a voltage signal
proportional to one of the

speed sources, or from the RS-422 link, or from the
keypad. This output ranges from 0 to +10 VDC. The source and level of this output is set by
parameters #28 (source of the output signal), #29 (the lowest value for the output), and #30
(the highest value for the output). See page 21.

OUTPUTS SUPPLY CONNECTION
An external power supply MUST be used to power any devices connected to
these outputs
.
These outputs are "open collector" outputs with all of the emitters brought
together at TB1 terminal 14 (see figure 2). The positive side of the supply has to be connected
to TB1 terminal 22 (this supplies the drivers on the board), and the negative side of the supply
must be connected to TB1 terminal 14. All of these outputs are isolated from the
DIGIMAX
