Introducing the TSX AEY 414 module

Overview

The TSX AEY 414 module is a multi-range acquisition device with four inputs isolated from each other. This module offers the following ranges for each input, according to the selection made at configuration :

thermocouple : B, E, J, K, L, N, R, S, T and U,
voltage: -13...+63 mV,
thermowell Pt100, Pt1000, Ni1000 in 2- or 4-wire, or Ohmic range : 0...400 Ohms, 0...3850 Ohms,
high level +/-10 V, 0...10 V, +/-5 V, 0...5 V (0...20 mA with external shunt), or 1...5 V (4...20 mA with external shunt). It should be noted that external shunts are supplied with the product.

NOTE: The terminal block is supplied separately under the reference TSX BLY 01.

Summary

The TSX AEY 414 input module performs the following functions :

Description

Details of the functions are the following :

Address	Component	Function
1	Connection with process and Input Channels Scan	hardware connection to the process through a screw-type wiring terminal, Gain selection, based on characteristics of input signals, as defined in configuration for each channel (high-level range, thermocoupe or thermowell), multiplexing.
2	Scanning of Analog Signals Measured at Input	Scanning of Input Measurements Analog Signals
3	Translating incoming values into workable measurements for the user	Taking into account recalibration and alignment coefficients to be applied to measurements (channel per channel, and range per range), as well as the module's self-calibration coefficients, linearization of measurement provided by thermowells Pt or Ni, linearization of measurmenet, and accounting for the internal or external cold junction compensation, in the case of thermowells, scaling of measurements, based on configuration parameters (physical units or user-specified range).
4	Interface and Communications with Application	managing exchanges with CPU, geographic addressing, receiving configuration parameters from module and channels, sending measured values, as well as module status, to the application.
5	Module Power Supply	-
6	Module monitoring and sending error warnings back to application	testing the conversion string, testing for range overflow on channels, verifying that terminal block is present, testing of sensor connection [except for ranges +/-10 V, 0...10V, +/-5 V, 0...5V (0..20mA), watchdog test.
