PowerLine User Guide
Module Connections:
+Power ( connector terminal 1 ):
This is the main + Voltage power supply input for the module. The PowerLine controller will accept 9 to 30VDC.
NOTE:
Make sure the unit has an in-line fuse fitted to protect the system, the module and the warranty.
+Coil A ( Connector terminal 2 ):
This terminal should be connected to the ‘A’ coils positive (+) connection. It is switched ON or OFF to decide
which if any coil will be driven. These terminals should not be connected to +Power.
+Coil B ( Connector terminal 3 ):
This terminal should be connected to the ‘B’ coils positive (+) connection. It is switched ON or OFF to decide
which if any coil will be driven. These terminals should not be connected to +Power.
-Coil A ( Connector terminal 4 ):
Both
- Coil A and -Coil B are internally connected together on the card and should be connected to the negative
coil leads. These are used to sense coil current, control the internal feedback circuit that maintains and
regulates current to the coils to recover from heating effects and should never be grounded.
-Coil B ( Connector terminal 5 ):
Both
- Coil A and -Coil B are internally connected together on the card and should be connected to the negative
coil leads. These are used to sense coil current, control the internal feedback circuit that maintains and
regulates current to the coils to recover from heating effects and should never be grounded.
Power Com ( Connector terminal 6 ):
This is the main 0 Volts ( GND ) power supply connection for the module.
Sig Com ( Connector terminal 7 ):
This terminal is internally tied to Power Common ( Power Com ) on the card. To provide the best possible
noise resistance Sig Com should be used as the only ground for the pulse and command sensors.
Command In ( Connector terminal 8 ):
This is the analog command input for the controller. The Graphical User Interface (GUI ) allows the user
through software to choose from several selectable ranges including 0 to +5-Volts, 0 to +10-Volts and +4-20mA.
There is also the facility that lets the user choose Uni or Bi-directional operation by setting the inputs so their
respective mid points become the zero crossover point ( i.e. 0-5V becomes 0 – 2.5– 5) with 2.5V representing
NO drive to the valve coils.
This input has an impedance of 100 KOhms when ‘Voltage Mode’ is selected and is internally pulled low to allow
for error detection and avoid spurious signals if not used.
Pulse In ( Connector terminal 9 ):
This is a programmable range input that accepts pulses above up to 30KHz. Pulses must cross the midpoint of
the range selected to be detected and may exceed the range without damage to the unit if less than +/- 30-Volts
Peak. Selectable ranges include –1 to +1V, 0 to 1.25V, 0 to 2.5V, 0 to 5V and 0 to 10V. A GUI software switch
is provided to allow the user to activate an internal 10KOhm pull down resistor on this input. Activation of the
pull down resistor is intended to provide loading for inductive, sourcing or open emitter sensors.
