1260-30A-D Multiplexer Module
The Racal Instruments™ 1260-30 is a high-power scanner/multiplexer configurable as eight 1x5, four 1x10, two 1x20 or one 1x40 two-wire multiplexer networks.
Key Features • 1260-30 configurable as any of the following two-wire networks: − One 1x40 multiplexer − Two 1x20 multiplexers − Four 1x10 multiplexers − Eight 1x5 multiplexers • 10 MHz bandwidth • Switches up to 2 A and 250 V • High power multiplexer • Provides circuit pads for user supplied terminators
Product Information The 1260-30 is ideal for switch applications where multiple channels have to be scanned or multiplexed on to a common bus, as is the case in scanning UUT test points with a DMM or in continuity testing. Relay coil current monitoring is available to provide confidence checking which gives the user assurance of proper relay operation. Mounting holes associated with each channel permit installation of user supplied components. The 1260-30 is controlled by the Racal Instruments™ Option 01 message-based interface.
