4 Channel Analogue Input Module
9-2
The resistance input variant may be used with two or three wire transducers.
Automatic compensation for lead resistance is provided when used with three wire
sources.
The process level input variant permits direct connection of high level (up to 10v)
signals, without the need for external attenuation.
Current inputs are handled by means of an external burden resistor fitted to the
detachable connector assembly. A 5 ohm burden permits the 50mV linear range to
represent 10mA full scale. For 20mA inputs the range should be set to 100mV.
The .../mV3/HiZ1 variant is hardware configured to give one channel of high input
impedance for high level (up to 10V) and three standard mV/thermocouple inputs.
The ...V2/FV2 variant is hardware configured to give two channels of frequency
measurement for tachogenerators or low speed encoders, and two channels of high
level (up to 10V) signal measurement.
All channel configurations are user configurable via the supporting Function Block
and the PC based Programming Station.
All modules offer four ranges. Range selection is made via the supporting Function
Block and the PC based Programming Station. Refer to the 'PC3000 Function Block
Manual' for further details.
Module identification
Module may be identified by means of a label visible through the top of the detachable
fascia carrying the text AI 4.
Additionally, a label fitted to the side of the module carries details of serial number
etc. The modules product code is included and should read:
PC3000/AI/VERSION3/mV4 for millivolt inputs
PC3000/AI/VERSION3/mA4 for current inputs (includes burdens)
PC3000/AI/VERSION3/V4 for process level inputs
PC3000/AI/VERSION3/RT4 for resistance thermometers
PC3000/AI/VERSION3/mV3/HiZ1 for Zirconia probes
PC3000/AI/VERSION3/V2/FV2 for frequency inputs (0-10kHz)
