Integrated analogue channels and analogue I/O
modules
Analogue I/O modules do not require an external power supply: energy is provided
via the TSX Micro PLC power supply. For maximum reliability, these modules do not
contain any electromechanical components: there are no multiplexing relays, no
configuration switches, and no adjustment potentiometers. These modules only
contain solid state components, and are configured using PL7 Micro or PL7 Junior
or PL7 Pro software.
These modules (TSX AEZ 801 and TSX AEZ 802) are analogue input modules,
with 8 high level multirange voltage or current channels. For each input, they offer
a choice between + 10 V or 0...10 V (TSX AEZ 801) and 0...20 mA or 4...20 mA
(TSX AEZ 802) ranges, according to the selection made in the configuration.
The various functions of the TSX AEZ 801/802 analogue input modules are as
follows:
b Scanning of input channels used by solid state multiplexing (normal or fast) and
acquisition of values.
b Analogue/digital conversion (11 bits + sign or 12 bits) of input signals.
The processing performed by the PLC processor, in addition to these functions:
b Monitoring of input overshoots.
b Filtering measurements.
b Converting input measurements to user format for display in directly readable
units.
The TSX AEZ 414 module is an analogue input module with 4 different channels.
Depending on the selection made in configuration and for each channel, it provides
the thermocouple, temperature probe or high level voltage and current ranges via
external resistors supplied with the module (see page 3/7 for the various ranges).
The functions of the TSX AEZ 414 analogue input module are as follows:
b Selection of the input range of each channel.
b Scanning of input channels by multiplexing and acquisition of values.
b Analogue/digital conversion (16 bits) of input signals.
b Monitoring of input value overshoots and sensor connections.
b Automatic linearization for Pt 100 and Ni 1000 temperature probes.
b Automatic linearization and internal or external cold junction compensation
for thermocouple ranges.
b Converting input measurements to user format for display in directly readable units
(physical units or user range).
b Detection of sensor connection faults for thermocouple ranges.
The TSX ASZ 401 module provides 4 common point analogue outputs (+ 10 V or
0...10 V). The TSX ASZ 200 module offers a choice between + 10 V, 0...20 mA and
4...20 mA ranges for both the common point outputs.
The various functions of the TSX ASZ 401/200 analogue output modules are
as follows:
b The acceptance of digital values corresponding to analogue values obtained as
output. These values are calculated by the PLC task to which the channels are
assigned (MAST or FAST).
b Processing dialog faults with the PLC and setting the outputs to fallback state
(value 0 or maintained).
b Selection of the range for each output: voltage or current (module TSX ASZ 200).
b Analogue/digital conversion (11 bits + sign) of output values.
