2-8 Installation & Wiring
Output Wiring
Output Types The outputs available depend on the PS-6144 Model:
Output Model Model
Type 6144-24M17 6144-24-X16-M09
Transistor None Outputs 1-16
AC/DC/RR Modules Only Outputs 1-15 Outputs 17-23
AC/DC/RR or Analog Modules Outputs 16 & 17 Outputs 24 & 25
The load device to be driven must match the output type.
Power Output Modules Output modules can directly switch inductive loads and resistive loads that require more
current or voltage than the transistor outputs can supply. The modules do not supply
the power for the load; they simply switch it. Each output module has two dedicated
terminals and therefore does not share any common signal with the other modules.
This allows AC and DC modules to be mixed on the same control. DC modules can be
wired to sink or source as shown in Figure 9.
Analog Output Modules Analog output modules generate signals that are proportional to the resolver RPM.
They can be used only in the output positions shown above. Either a 0-10 VDC or 4-20
mA analog module can be used in either module position. ANALOG QTY must be
programmed for the number of analog modules installed. An external power supply is
not needed because the analog modules get the power they source from the controller.
The analog output signal is completely isolated.
Transistor Outputs PS-6144-24-X16-M09 models include 16 transistor outputs to drive the electronic input
circuits of other control devices. The outputs are limited to 30 VDC, 50 mA each and
should not be used to control inductive devices such as solenoids, solenoid valves or
relays.
The control can be ordered with either sinking or sourcing transistor outputs. Both types
require a 10-30 VDC power supply connected to TB 11 to drive the transistor output
circuitry. The transistor output fuse will blow if the power supply polarity is incorrect, but
the circuitry will not be damaged. See Figs. 17 & 18 for fuse and transistor chip replace-
ment.
Sinking transistor outputs (N16 controls, Figure 10) conduct to the negative termi-
nal of TB 11. Therefore the common for TB 11 and the load must be electrically the
same. This may require connecting commons together if the power supplied to TB 11 is
not also the load power supply. Electronic counters/ratemeters often fall into this cat-
egory. The power supply that powers the load does not have to be the same voltage as
the transistor power supplied to TB 11.
Sourcing transistor outputs (P16 controls, Figure 11) conduct to the positive power
terminal of TB 11. The load is therefore powered from the same supply that is providing
the transistor power.
