OPT-1020, OPT-1120
The OPT-1020/1120 daughter board series provides the analog inputs isolation for the DAQ cards.
The module provides one isolated channel with the jumper-selectable gain (1x/10x) and frequency bandwidth depending on the type. Unlike the multiplexers, this module does not expand the number of analog inputs and it also does not need any control (it works software transparent).
The CAB-2511/2 cable (not included) is used for connection the OPT-1020/1120 board with the DAQ card. If the DAQ card provides the 12V power supply voltages, the OPT-1020/1120 board is powered from the card via CAB-2511/2 cable; if not, external power supply must be used.
If multiple OPT-1020/1120 boards are used, an interconnection cables CAB-1004C and CAB-2604C (up to four boards), or CAB-1008C and CAB-2608C (up to eight boards) are required (not included). Whole set of boards can be connected to the DAQ cards via CAB-2511/2. Please pay attention to the maximum current capacity of the DAQ cards power supply output. Most of DAQ cards are capable to power two or three boards, for higher number it is necessary to use external power supply.
