PS25014A1 Datasheet, PDF (2/3 Pages) List of Unclassifed Manufacturers – APPLICATION BOARDS FOR EPIC SENSOR PS25401A

PS25012A1, PS25012B1
Electrical Characteristics
These electrical characteristics apply to the PS25014A1 and PS25014B1 application boards that carry the PS25401A
sensors. The electrical characteristics (@25^oC) are guaranteed by either production test or by design and
characterisation. They apply within the specified supply voltage unless otherwise stated.

Conditions/Notes
Each PS25401A sensor consumes
2.0mA (typ). The additional current
is consumed by the app’n board.
Electrical Connector
The PS25014A1 and PS25014B1 application boards are fitted with one or two five pin sockets. The connectivity of
these sockets is shown below:

Not used
The supply and ground connections of the two sockets on the dual channel PS25014B1 board are connected in
parallel so that the board will be active with either one or both connectors in use. However, when both sockets are
powered the supplied voltages must be identical.
Auxiliary Components
PS25000A
Control and Interface Box; 50Hz.
This box provides power for one or two sensors. It incorporates switchable low pass and 50Hz notch
filters. The box contains an amplifier with switchable gain of either x1 or x10. The box also generates
a differential signal from two sensors. The box incorporates a data acquisition card that provides the
data from the sensors via a USB cable to a computer. The box is powered by the USB connection. A
soft scope is provided with this box for display of the signals on a computer.
PS25001A
Control and Interface Box; 60Hz.
This box is identical to the PS25000A except that the switchable notch filter is preset to reject 60Hz.
PS25013
Adapter cable.
This 1.5m long cable connects the sockets of the EPIC application boards to the PS25000A or
PS25001A Control and Interface Box.
