Astronics 1260-114TTL - 96 DIO TTL


Description

Carte fille 96 voies TTL


The Racal Instruments™ 1260-114 is a 96-channel digital I/O plug-in for the Adapt-a-Switch® platform. A 48-channel high voltage/current open-collector version is also available. The 1260-114 installs easily and directly from the front panel into the Adapt-a-Switch VXIbus Carrier, 1260-100. Please refer to the 1260-100 data sheet for specifications and product features.

The 1260-114 is available in TTL , CMOS, OC (standard open collector) or HVOC (high voltage/current open collector) I/O channels. Each TTL or CMOS I/O channel may be placed in a high impedance, tri-state mode. Additionally, the CMOS version features TTL level compliance, provided the maximum current of the driver is not exceeded (refer to the specifications).

The high channel count of the digital I/O plug-ins allows a significant portion of digital I/O to be realized in a single slot of the Adapt-a-Switch Carrier, saving valuable VXIbus chassis space. The 1260-114 provides 96 digital I/O channels in twelve groups of eight bits each. The 1260-114OC version can utilize a separate external pull-up supply for up to 32VDC for each independent group, and the 1260-114HVOC can utilize a separate external pull-up supply for up to 50VDC. The versions are ideal for controlling external digital circuitry, switches, relays and similar devices. Each channel is configurable as an input or an output and can be individually controlled in asynchronous mode or with other channels in synchronous mode.

The 1260-114 has a two-wire handshake mode available for the control of synchronous I/O transactions. Each handshake line can be programmed as either active high or active low providing a flexible interface with user signals.

The 1260-114 is programmable in several operating modes and data may be manipulated in either hex, decimal or binary. Memory is available on the 1260 Series Option-01T Switch system controller to allow buffered I/O operations.

An Option 01T is required to communicate with Adapt-a-Switch plug-ins, and it provides message-based operation for ease of use and register-based operation for maximum speed. The Option 01T is installed in the leftmost Adapt-a-Switch carrier or 1260 series module and does not occupy any VXI or plug-in slots. The Option 01T provides a single point of software control for the switching system with advanced features such as include, exclude, scan, relay monitoring, user-defined path names, and reset states.

The Adapt-a-Switch series includes VXIplug&play support for WIN95/NT frameworks, including drivers for LabWindows/CVI and LabVIEW. Please refer to the Option 01T data sheet for additional product features.
