The Astronics 1260-14 Digital I/O Switch Card provides 96 open collector channels in 12 groups of eight bits each. With the open collector version each independent group can utilize a separate internal or external pull-up supply up to 32VDC.

Each channel can be configured as an input or an output and individually controlled in the asynchronous mode, or be synchronous with other channels.

Product Information

Compatible for use on VXI platforms, this switch product was formerly sold under the Racal Instruments brand name.

The 1260-14 has a two-wire, handshake mode available for the control of synchronous I/O transactions. Each handshake line can be programmed to either active high or active low to provide a flexible interface with user signals.

Key features:

*96 TTL, CMOS, or open-collector input/output channels
*Drives up to 32 V and sinks up to 200 mA per channel
*Two-wire programmable handshaking
*Synchronous, asynchronous, and mixed operating modes
*1 kHz data rate
