DAT804 Thermocouple Temperature LED Digital Indicator.

GENERAL DESCRIPTION

The DATEXEL DAT804 is a 3.5 digit LED digital indicator with high accuracy and reliability able to read inputs from Thermocouple probes.

The DATEXEL DAT804 is designed for mounting in a panel in accordance to DIN 43700 standard. It also has a function to freeze (HOLD) the display.

It is possible to set, by jumper, the input attenuation ratio of the display (x 10 and x 100) and the decimal point position.

The DATEXEL DAT804 is in compliance with the directive CEE/336/89 on the Electromagnetic Compatibility.

The power supplies available are 24Vdc isolated, 110Vac, 230Vac and 5Vdc.

As an option, a 24Vdc output can be available to power the current loop transmitter.

The instrument, conforms to the 89/336/EEC directives on electromagnetic compatibility, and is housed in a case complying with DIN 43700 standards.

USER INSTRUCTIONS

Sensor: The instrument is designed to visualize a temperature measure detected by a thermocouple connected as illustrated in the wiring diagram. The instrument can be supplied for thermocouple K, J, S, N, E or T and the type desired must be indicated on the order.

Range: In the table below are illustrated the standard ranges; These ranges are normally sufficient to cover the most general requirements. However, on request, is possible to supply the instrument with a particular range, in order to obtain more accuracy or better resolution in a narrow range, or with a larger range than the standard.

The thermometers are supplied perfectely calibrated, however it is possible to make some little adjustement in field by using the two trimmers inside, after removing the front panel (see "Adjustments view").

Power supply: In the figure and table below are illustrated the arrangements and the terminal designation in order to make the correct wiring. When utilizing instrument with option 02 a regulated power supply of 5Vdc ±5% is recommanded and in any case avoid to exceed a value of 5.5Vd because permanent damage can arise to the instrument.The power consumption depend principally on the type of display selected and it is indicated in the "technical specifications".

24 Vdc auxiliary output: When ordered with Opt. 05, it is available between T4(V+) and T6(GND) terminals.

HOLD FUNCTION or ANALOG OUTPUT:

To activate this function, simply HOLD(T5) terminal must be connected to COM (T6) terminal. The same terminal T5, when you have requested option 07, provides the analog output: 4-20mA (opt. 07/A), 0-20mA (opt. 07/B), 0-10V (opt. 07/C).
