APPENDIX A - TECHNICAL SPECIFICATION
Technical Specifications:
Specifications are indicative and subject to change. Actual performance will vary depending on the application and operating conditions. Users
should satisfy themselves that the product is suitable for use in the intended application. All our products carry a limited warranty against defects in
material and workmanship. Please refer to our Warranty, Application Approvals/Limitations and Return Materials Process as described on
www.axiomatic.com/service.html.
Input Power
Power Supply Input - Nominal
12, 24VDC nominal (8…36 VDC power supply range)
Surge protection is provided.
If batteries are used, an alternator or other battery-charging device is necessary to
maintain a stable supply voltage. Central suppression of any surge events should
be provided at the system level. The installation of the equipment must include
overcurrent protection between the power source and the module by means of a
series connection of properly rated fuses or circuit breakers. Input power switches
must be arranged external to the Axiomatic Control Module.
Power input wiring should be limited to 10 meters.
Quiescent Current
300 mA at 12 Vdc Typical
155 mA at 24 Vdc Typical
Inrush does not exceed 500 mA.
Protection
Reverse polarity protection is provided.
Power supply input section protects against transients, surges (per IEC 60533,
Table 4) and short circuits and is isolated from inputs.
Undervoltage protection is provided and hardware shuts down at 7.5Vdc.
Over-voltage protection is provided, and hardware shuts down at 41Vdc.
Inputs
Universal Signal Inputs
Up to 10 inputs are selectable by the user. All inputs, except for frequency, are
sampled every 1ms. The user can select the type of filter that is applied to the
measured data, before it is transmitted to the bus. The available filters are:
Filter Type 0 = No Filter
Filter Type 1 = Moving Average
Filter Type 2 = Repeating Average
Universal Signal Input
Configuration
Up to 10 inputs are available.
Refer to Table 38.0.
Each input can be configured for any one of the following options.
Disable input
