9.1 SETPOINTS


An option of 2 or 4 SETPOINTS, programmable within the full display range, can be incorporated to the unit thus providing alarm and control capabilities by means of individual LED indicators and relay or transistor outputs.

All the setpoints provide independently programmable value, time delay (in seconds), asymmetrical or symetrical hysteresis (in counts of display) and selectable HI/LO acting. The setpoints are also configurable to activate independently (each one activates at its corresponding programmed value) or tracking one another (setpoint 2 can be conditioned by the action of setpoint 1, setpoint 4 by setpoint 3). Such latter function is included in the programming menus with the name of TRAC and, in case of the setpoint 2, it can be manual or automatic. 
The setpoint option consists of a plug-in additional card that once installed to the meter's main board, activates its own programming module. The setpoints programming may be locked out by means of DIP-switches located on the main board to prevent from accidental or unauthorized changes.

The available alarm/setpoint output options are the following:

2RE: 2 SPDT relays rated 8A
4RE: 4 SPST relays rated 5A*
4OP: 4 isolated open-collector transistors NPN
4OPP: 4 isolated open-collector transistors PNP

These type of outputs, capable of carrying out a wide variety of control operations and processing of limit values, increases notably the unit's performance qualities thanks to the possibility of combining basic alarm functions with advanced safety and control applications.

9.2 Analogue 0-10V, 4-20mA


Two ranges of analog output (0-10V and 4-20mA) can be incorporated to the KOSMOS instrument by means of an additional card (ANA option) which is installed on the meter's main board via plug-in connectors. The outputs are opto-isolated with respect to the signal input.

The optional board provides a two terminal connector [ANA(+) and ANA(-)] that drives out a signal variation from 0 to 10V or from 4mA to 20mA proportional to a user-defined display range.

This way, the meter is furnished with an output signal that can be utilized for proportional control purposes and also be used to drive a variety of terminal equipment such as graphic recorders, controllers, remote displays or other devices that accept input data in analog form. An exceptional feature is the possibility of setting the rate at which the output signal may change by either making it follow the display or the input signal conversion rate.

Output Option


The BCD output option delivers 5½ digits in BCD (8.4.2.1.) form through a 34-pin connector that provides 21 output DATA lines, DATA VALID, POLARITY, OVERRANGE signals and TRIESTATE input, plus power inputs to feed the circuit card. The 34-pin rear connector can be adapted to interface with 37-pin SUB-D terminals by means of a cross-wire adaptor supplied with the option. All the outputs are compatible with TTL and 24V logic and they are opto-isolated with respect to the input signal whenever the card is powered from an external source of 5V or 24V.
BCDoption, that can be installed in models ALPHA and BETA, is supplied independently with an instructions manual and the following accessories :

. Adaptor for 37-pin SUB-D connector.
. Integrated circuits for changing the logic.
. Instructions manual.

OUTPUT OPTION


Two ranges of analog output (0-10 V y 4-20 mA) can be incorporated to the new MICRA family by means of an additional card, either the NMV card for voltage output or the NMA card for current output, which is installed on the meter's main board via plug-in connector M3, both cards, cannot be used simultaneously.

The outputs are opto-isolated with respect to the signal input and the power supply. The optional board provides a two terminal connector [(+) and (-)] that drives out a signal variation from 0 to 10V or from 4mA to 20mA proportional to a user-defined display range. This way, the meter is furnished with a signal that can be used to control variables and operates at each moment proportionally to the magnitude of the effect under control.
These signals can also be used to transmit display information to a variety of terminal equipment such as graphic recorders, controllers, remote displays or other devices that accept input data in analog form.

The instrument will detect the type of option that has been installed and will operate in accordance.

The display values producing the full scale output (OUT-HI and OUT-LO) are also introduced via front-panel buttons in the same programming module. The analog output then follows the display variation between the HI and LO programmed points. The output signal can be set up for reverse action by programming the low display for the high output (OUT-HI) and the high display for the low output (OUT-LO).
