Opciones de Temperatura y Voltaje Auxiliar 14701/14702/14703

General

El Sistema Electroquímico y de Prueba de Baterías Multicanal Solartron 1470E dispone de Tarjetas Opcionales que incluyen medidas de voltaje auxiliar externo (tanto para DC como para impedancia), medidas de temperatura externos y control de dispositivos externos.

14703A  Opción de Temperatura & Control de Salida (solo para 1470E)
14701A  Opción de Temperatura & Control de Salida (solo para 1470A)

The 14701A provides eight temperature measurement channels which are compatible with E, J, K and T type thermocouples. Each main channel has one temperature measurement channel assigned which can be used to terminate a schedule step, provide temperature safety limits or simply monitor the battery temperature.

The temperature range covered is a function of the type of thermocouple. This allows, for example, fuel cells to be tested at very high temperatures, beyond 1000ºC, or climatic tests to be run on cells below freezing point.

In addition, the 14701A option provides control switches which may be used to control external devices such as valves, relays or heaters. Solid state switches are used (two terminal devices which can be used in similar ways to relays). Each switch is opto-isolated and is independent of the others. They can be connected to external supplies (up to 50V) as required to provide switching signals.

External devices can be switched on and off at each step in a schedule. Since schedule steps can be of very short duration this can provide fast switching if needed.

La opción 14703A con el software CellTest suporta:

· Temperature safety limits

· Temperature measurements with plot vs time and other parameters

· Temperature step termination limits.

A connection cable is provided between the instrument and the thermocouple interface unit which provides the cold junction compensation (1 metre length). Thermocouples must be purchased separately to suit temperature range requirements etc. (These are not included with the option).

Control Outputs
24 switch outputs are available (each main channel has 3 control outputs assigned). These switches are similar to relays.
Type - Opto-isolated solid state switches
Connections - 2 per switch
Max voltage - 50V
Max current - 100mA

Switch settings can be automatically changed at each step in a schedule. The switches can be used to control external devices (relays, lamps, heaters, valves etc). A D-type connector is provided for customers to make up their own connection leads.

14702A  Opción de Entradas Auxiliares de Voltaje

The 14702A is used in conjunction with the 14701A and provides an additional eight differential voltage measurement channels which can be used to monitor voltages within the fuel cell or battery under test. The auxiliary voltage inputs can be connected across anodes or cathodes within the cell to provide high speed DC voltage measurements of individual electrodes (e.g. for analysis of mobile phone GSM pulses or for ohmic drop experiments).

The maximum data acquisition rate is 10,000 samples per second on the auxiliary voltage channels and these are precisely synchronised to the measurements on the associated main channel. This allows electrode effects to be precisely related to effects in the whole cell.

Especificación:

Auxiliary Voltage Channels
Number of channels - 8
Max. aux. channels per main channel - 4
Max. appplied voltage (Hi or Lo to chassis) - 10V
