The PowerMate 8 (PM8) receives switch commands from the keypads, interfaces or CANbus and then processes
these commands based on the current system status. The response to a switch command may be an activation or
deactivation of a circuit, the start of a timed function or in systems with keyless ignition the locking or unlocking of
the system.
The PM8 then sends the system status information to turn on/off the indicator LED’s and backlights. The PM8
incorporates solid state technology which uses MOSFET’s for switching and over-current protection.

DETAILED DESCRIPTION
DETAILED DESCRIPTION
PowerMate 8 has 8 MOSFET Outputs which are rated at 20 Ampere each maximum. All outputs can ONLY be
Switched to Battery. Each Output is double protected by hardware and software, i.e.
MOSFET OUTPUT
MOSFET OUTPUT
PowerMate 8 can shut down the MOSFET in case of Over-Current and
In case of software exception, the fuse will be blown to protect the circuit from further damages.
PowerMate 8 has 8 Binary Inputs which are capable of reading Digital High/Low Input. Each Binary Input can be
configured as Switch to Ground (STG)/Switch to Battery (STB) and High/Low Active independently:
BINARY INPUT
BINARY INPUT
STG Active Input examples: - Park Brake, Door Switch, Locker Doors etc.
STB Active Input examples: - Ignition, PTO, High Beam etc.
1.
2.
ALL Binary Inputs by default are configured as STB Active Inputs.
PowerMate 8 has one RS-485 channel. It can communicate with other PowerMate Series Digital Switching modules
and Keypads within the system network using the OmniBus Interface.
OMNIBUS INTERFACE
OMNIBUS INTERFACE
PowerMate 8 is default configured to communicate at 9600 bps (9600, 8-N-1).
The user can retrieve system status such as output and input pin conditions, current status, analog input
values as well as battery status.
PowerMate 8 has one CAN channel. It can communicate with other PowerMate Series Digital Switching Systems
using CAN Interface.
CAN INTERFACE
CAN INTERFACE
PowerMate 8 is default configured to communicate at 250 kbps.
PowerMate 8 supports CAN protocols such as J1939, CANOpen, CANStandard etc.
Common Status that the PowerMate Series Digital Switching Systems would be able to obtain from the
CANbus include:
Vehicle Speed
Engine Revolution Per Minute
Gear Position
Further customisation is possible to suit specific client requirements.

INSTALLATION OVERVIEW
INSTALLATION OVERVIEW
The Keypad and PowerMate units should be inspected for physical damage before installation. Any cracked, broken
or bent items on either unit should be reported to your local dealer of DSSA for proper disposition.
Ensure all power is off by disconnecting the battery(s) from the system or de-energizing the battery switch.
Prepare the unit for installation by removing all packaging materials. Keypads must be mounted to a flat surface
using a properly positioned cutout for the keypad connector pigtail. The keypad mounting studs should be secured
through the panel using 10-32 UNF nut and lock-washer. Tighten the nuts to snug only.
Do NOT exceed torque ratings as advertised of 7 1 in. lbs or 0.79 N.m as this will crack or deform the keypad,
which will cause intermittent operation.
Connect the keypad pigtail Deutsch connector to the wire harness (wire harnesses are not provided by DSSA). They
must be designed, manufactured and installed to meet the DSSA requirements as well as the specific design
requirements of the application, for length, termination, wire size, etc. It is the installers responsibility to ensure this
has been done to meet or exceed design specifications.
To mount the PowerMate, the unit must be installed in a dry, well ventilated space inside the vehicle cabin. The
ambient temperature must not exceed 70°C. It is recommended that the PowerMate be mounted with the plugs
facing in a downward direction or to the rear of the installation to minimise potential damage to the plugs, harness
and studs.
Secure the PowerMate with four bolts, nuts and washers or equivalent wood screws (not provided).
Secure the negative power side terminal to the negative power lug and secure with the nut and washer provided.
Secure the positive power side terminal to the positive power lug and secure with the nut and washer provided. Take
care to never reverse the terminal connections or reverse the order of connection.
Do NOT exceed recommended torque ratings as advertised of 12 3 in. lbs or 1.36 N.m. Over tightening will
cause the lug nut to crack or fail.
The main battery supply to the PowerMate must be protected by a switchable circuit breaker positioned at the
battery. This enables the PowerMate to be isolated from the battery in the event of charging or changing the
battery(s).
The PowerMate 8 is limited to a maximum voltage supply of 30 volts.
Plug Deutsch connectors (ensuring the correct key is selected) and then apply battery power. The system is now
ready for power and operation. Re-connect the main battery(s) to the circuit and follow the operational instructions
below.

_
When a button on the keypad is pressed, the circuit for that button will turn on. The indicators on all keypads for that
circuit will light up to show circuit is on. Any DSSA Keypad can turn a circuit ON or OFF.
If a circuit draws more than the rated current, the circuit will be turned OFF and the indicator LED will flash to
indicate circuit was Tripped, To REST the circuit, Press and Hold the Keypad button down for 6 seconds.
The system will also detect and indicate faulted circuits. A faulted circuit can be wither an open circuit such as a
defective device (burnt out bulb) or dead short circuit. When an Output fails, the operator can Press and Hold the
Keypad button with the Flashing LED for 6 seconds, to REST the Output. The Output can now be tried again.
GENERAL FUNCTION
GENERAL FUNCTION
To un-install the PowerMate from the system, the steps taken should be the reverse of the installation sequence.
Do NOT disconnect the power terminals while the Deutsch connectors are still attached.
Failure to disconnect the Deutsch connectors first, may cause the PowerMate to receive reverse current causing
failure of the unit and voiding any warranties.

KEYPAD FUNCTIONS
KEYPAD FUNCTIONS
Toggle:
The circuit is on while the button is held down.
Momentary:
Momentary Interlock:
The circuit is on while the button is held down but will not turn on while
an interlock circuit is on.
Constant/Always ON: The circuit is always on.
Countdown: The circuit is turned on with the first press of button, and then after a
predetermined time in seconds the circuit will automatically turn OFF.
Toggle/Dimmer:
The first press turns the pin ON. Holding the button down on the second
press will decrease voltage on pin until zero power is reached. Pressing
the button a third time will turn pin OFF.
One-hot Scroll:
One press of the button turns on one circuit, and then each additional
press turns on a different circuit. Only one circuit is activated at a time.
The last press turns off all circuits.
Reverse Inclusive Scroll: With the first press of a button, all circuits are turned on. Each press
thereafter turns off one circuit. The last press turns off all circuits.
