OPT-861

The OPT-861 daughter board provides optical isolation and signal conditioning of the DAQ cards output digital ports.

The board provides eight output blocks (isolated between each other) for switching DC or AC signals (reed relays are used as a switch). All channels work as noninverting, i.e. high level on control port activates the output relay.

The control port operates in TTL/HC mode, but with output current at least 12mA at signal voltage 4V (meets all DAQ cards TEDIA).

Every channel is fitted with an indicating LED, signalizing high level on control port.

The CAB-0911/2 cable (not included) is used for connection the OPT-861 with the DAQ card, respectively PCE-16xx adaptor.

Delivery details
