EADS North America Test and Services Racal Instruments™ 1260-X121 20-Channel, 10 A Power Switch Plug-In The Racal Instruments™ 1260-X121 is a 20-channel SPST switch plug-in for use in the Racal Instruments™ 1260-100 Adapt-a-Switch™ VXI carrier. Key Features • 20 Channels of SPST switches • Software configurable as 10 DPST or 10 1x2 • Switching for power supplies and current sources • Switches up to 10 A, AC or DC Product Information The 1260-X121 is configurable as 20 channels of SPST, 10 channels of DPST, or 10 channels of 1x2. Each channel of the 1260-X121 switches up to 10 A, making it the ideal solution for applications requiring high-current switching of AC and DC power supplies, as well as current sources. When used with the 1260-100X Adapt-aSwitch™ platform, a Racal Instruments™ Option 01T is required to communicate with any set of switch cards. The Option 01T provides message-based operation for ease-of-use and register-based operation for maximum speeds. An IVI-COM driver is available for this module. Our advanced “Exclude” feature ensures maximum safety when switching power. This Exclude command prevents simultaneous switch closures that could cause a short or other hazardous connection.
