The "ER" Module integrates full "E" Module functionality with the recording or data logging capability of the "R" Module.
This module provides 0.5 Mbytes of solid-state memory and records up to 20 channels at 50Hz sampling frequency per channel.
This module can record data from other Expansion or Display Modules. It can also be used as a Stand-alone Recording System.
The "ER" Module can monitor up to 8 universal inputs, each of which can be configured individually to accept any standard sensor or sensor interface from the Stack range. Alternatively each input can directly measure 0-5 volts, 0-333 Ohms, or a pulse frequency up to 40kHz. Each input can be sampled at up to 50Hz,
When used with Stack's range of 'digital' sensors and sensor interfaces, any sensor input can be configured to enable fast-changing parameters to be recorded slowly, by measuring the average parameter value throughout the sampling period, e.g. suspension movement with a maximum frequency response of 1kHz could be recorded at 10Hz for pitch and roll measurement, to extend the recording time and reduce the memory usage.
