The Racal Instruments™ 1260-136 series plug-ins are high-voltage relay multiplexers for the Adapt-a-Switch® platform. These quickly and easily plug into the front of an Adapt-a-Switch Carrier 1260-100. Please refer to the 1260-100 data sheet for Adapt-a-Switch platform features and specifications.
Each 1260-136 series plug-in can be configured via standard program control into any of the following configurations:
1260-136 plug-ins can be used for distribution applications in which any combination of relays per multiplexer are closed at a time, or in classical scanner applications in which only one relay per multiplexer may be closed. When used as a scanner, the 1260 series “exclude” feature will automatically open up the last connection when a new connection is programmed. This reduces the number of commands sent to the switch, reducing test time. Make-before-break or break-before-make can also be programmed.
Three different versions of this plug-in are available to support a range of high voltage switching requirements. Each version uses a different high voltage relay. Basic “hot-switching” specifications of these plug-ins are as follows:
The 1260-136D must be oriented vertically to operate properly. This is the normal position for installations using a 13-slot VXI chassis and Adapt-a-Switch carrier. The 1260-136B and C versions are not position sensitive; they will operate properly in installations oriented in any direction.
An Option 01T is required to communicate with 1260 series modules, and provides message-based operation for ease of use and register-based operation for maximum speed. The Option 01T mounts on the leftmost 1260 series module and does not consume any VXI 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 1260 series line includes VXI plug&play support of Win95/NT frameworks including drivers for LabWindows/CVI and LabView. Please refer to the Option 01T data sheet for additional product features and specifications.
