H3-GDSP-CITF
Complex input/transducer simulator I/O module
The Genix GDSP-CITF sensor simulator module are fully configurable DSP processing and signal conditioning I/O modules designed for a wide range of test and verification applications.
These modules are targeted at applications where the ability to easily re-configure the hardware and function of the interface is required. Such applications include hardware-in-the-loop testing systems and simulator interfaces.
The GDSP-CITF is designed for applications requiring complex input facilities and also supports enhanced transducer simulation capabilities on module, using the H3-GDSP-GUI for configuration and remaining configured thereafter.
Modules can be re-programmed and configured via a CAN interface and then act as input or output, analogue or digital processing modules complete with the appropriate signal conditioning. They can be used in either H3 carriers or DDIN units.
Analogue voltage and current input
Each module has 2 voltage inputs which can range from -60V to +60V. The (+) input has three fixed gain ranges and the configurable resistance may be optionally used (18Ω to 294KΩ) to pull up/down/across the measurement. The module’s (+) pin can also be configured as a current input from -20 to +20mA or -400mA to +400mA to 0V or -ve pin.
Digital voltage or current input
Each module has up to 2 inputs that can be used as digital voltage inputs, with optional configurable resistance (18Ω to 294KΩ).
The input can also be configured as a current input using the programmable resistance. Each input can have a programmable threshold from -50 to +50V.
Frequency or PWM inputs
Each module has up to 2 inputs that can be used as a PWM or frequency input.
Inputs can measure from 3Hz up to 200KHz.
Both PWM duty cycle and frequency can be measured.
Analogue voltage output
Each module has a single ECM analogue output.
The (+) pin can be used as an analogue voltage output range of -10V to +10V.
The output can sink or source up to 20mA.
Digital voltage output
Each module has two digital voltage outputs. Each of the (+) and (-) pins can output the 0V reference or VT which is the ‘top’ or pull-up voltage fed into the carrier or DDIN VT line. Outputs can sink or source up to 250mA and can be configured for pull high, pull low and half bridge modes, with optional programmable pull up or down resistance from 18Ω to 294KΩ.
Frequency or PWM outputs
Each module has two frequency or PWM outputs. Each of the (+) and (-) pins can output the 0V reference or VT which is the ‘top’ voltage. Outputs can sink or source up to 250mA and can be configured for pull high, pull low and half bridge modes, with optional programmable pull up or down resistance from 18Ω to 294KΩ.
Resistance simulation
Each module can be configured as either a differential resistance with a range of 18Ω to 294KΩ.
The module may also be configured as two configurable resistors, one of which has a range of 18Ω to 294KΩ, the other a fixed value of 15KΩ or open circuit.
Resistors are 60V capable, depending on their power dissipation, and are 12V continuously rated for most common requirements.
Crankshaft sensor angle simulation
Designed to simulate the outputs from engine crankshaft missing tooth sensors. There is generally a single crankshaft on an engine and the H3 modules can use this as the master angle that all other channels are referenced from. Thus the H3 output is an angular output and can be set as the master clock source for all channels within a ‘team’ of H3 modules, allowing all other channels within the team to be controlled from the same angle source.
Camshaft sensor simulation
Designed to simulate the outputs from an engine’s camshaft sensors.
The H3 camshaft simulation outputs can be configured to simulate both the desired sensor pule duration angle and the phase shift from any other cam or crankshaft signal.
By making use of the teaming features within the H3 carrier, up to 7 camshaft sensors and one crankshaft can be supported.
