Relay switch module 1260-22

The Racal Instruments™ 1260-22 is a 40-channel, SPST, high-power switch module designed for switching and routing high-current sources such as AC and DC power supplies in automated test systems. The 1260-22 switches currents up to 20A, AC or DC, and voltages up to 250VDC or 250VAC. Maximum power handling is 600WDC or 4800VA per channel. The 1260-22 design reduces external components, configuration jumpers and fail-safe devices. Provisions for internal jumpers facilitate 1x2 and/or 1x4 multiplexer configurations, reducing external wiring. Surge suppressors install easily onto the module, simplifying system integration. An external Emergency Reset switch may be connected to the front panel connector of the 1260-22. The external switch provides a way to instantly open all channels on the 1260-22, and all cards connected to the same Option 01T. This helps ensure safe switching in high-current applications. The message-based and register-based Option 01T interface controls the 1260- 22.Refer to the applicable Option 01T data sheet for specifications and product features, such as include, exclude, and scan lists; relay coil-current monitoring; and user-defined path names and reset states.The 1260-22 includes VXIplug&play support for frameworks based on Microsoft Win32® application programming interface,including drivers for LabWindows™/CVI and LabVIEW™ Key Features • 40 channels of SPST high-power switching • Switching for power supplies and current sources • Switches up to 20 A, AC or DC • Interface for external “emergency reset” switch to open all channels • Reconfigurable as multiplexer: five 4 x 1 plus ten 2 x 1 • Provisions for adding shunt contact protection element
