Astronics Test Systems Inc. Racal Instruments™ 1260-120 Power Switch Plug-In The Racal Instruments™ 1260-120 is a 20-channel, SPST (Form A) high-power, switch plug-in. It installs easily into the Racal Instruments™ 1260-100 and 1260-101 Adapt-a-Switch™ VXIbus carriers or the Racal Instruments™ 1256 GPIB and 1256L (LXI Core 2011 Compliant) switching mainframes. Key Features • 20 Channels of SPST high-power switching • Ideal for switching AC or DC power • Switches up to 13 A • Can be used in VXI, GPIB/RS-232, and LXI switching systems • Interface for external “emergency reset” switch to open all channels • Standard Adapt-a-Switch™ plug-in design for ease of replacement Product Information Each channel of the 1260-120 can switch up to 13 A, 250 VAC or 10 A, 125 VDC; its switching capability makes it the ideal solution for applications requiring high-current switching of AC power, DC power supplies, and AC or DC current sources. To ensure safe switching in high-current applications, an external "Emergency Reset” switch may be connected to the front-panel connector of the 1260-120 to provide the ability to instantly open all channels on the switch card, or to open all channels on all cards connected to the same Racal Instruments™ Option 01T. As all relays on the 1260-120 are electromechanical, all inputs/outputs are interchangeable to meet the test requirements. Mating front-panel connectors, complete with pins, are included with the 1260120. The Option 01T interface controls the 1260-120, using both register-based and message-based operation. Refer to the Option 01T data sheet for product specifications and features such as include, exclude, and scan lists; relay coil-current monitoring; and user-defined path names and reset states. The Adapt-a-Switch™ series includes VXIplug&play support for frameworks based on Microsoft Win32® application programming interface, including drivers for LabWindows™/CVI and LabVIEW™. 949.859.8999; 800.722.2528; atssales@astronics.com; www.astronicstestsystems.com Copyright © 2014 Astronics Test
