Product Description
The DAT5024-AO device is able to accept at its input a wide range of normalized voltage or current signals; it is also able to interface directly to thermocouple or resistance thermometer temperature sensors. The current input makes it possible to connect both active and passive sensors and converters, since a power source (Vaux) is available to power these devices. The thresholds can be configured using DIP-switches both as a maximum and as minimum. The trip level is set by acting on the potentiometer located on the front of the container. It is also possible to set, through potentiometer, the hysteresis and of the delay time for the thresholds.
If the configuration is performed by dip switches, the analog output is 4-20mA by default in relation to the ranges in the “Input type” table.
Through PC programming it is possible to set the type of input, the intervention and release thresholds, the delay and the analogue output without using the test points and the potentiometers.
The software programming procedure can be performed by interfacing the device to the Personal Computer, using the special CVPROG cable provided by DATEXEL and sold separately, without the device having to be connected to an external power supply.
The galvanic isolation eliminates all the effects due to the mass loops that may be present, allowing the use of the device even in the most severe environmental conditions.
