The Racal-Dana 1250 Universal Switch Controller allows signals to be switched in a single system from DC to 26.5 GHz. The 1250 Series is a general purpose switching system designed for both manual and automatic test systems. Low level, power, RF, and microwave switching requirements are addressed by the switch modules available in the 1250 Series.

The 1250 is designed for use in automatic test systems, but local control of the switching system is supported by Option 90, which supplies an intelligent front panel with a display and keyboard.

The 1250 is of a modular construction that allows easy removal and replacement of all major assemblies. These assemblies are as follows: Switch modules, Card Cage, Microprocessor Controller, Power Supply, and optional front panel.

The signals to be switched by the 1250 are routed through up to five plug-in relay cards installed in the 1250 chassis. These plug-in cards allow the 1250 System to be easily reconfigured as required.

The switching capabilities of the 1250 are enhanced by providing a 10-wire Analog bus. This allows switch modules to be interconnected to expand beyond the capabilities of each individual switching module. This is particularly useful in configuring large switching matrices. The Analog Bus may also be cut to separate selected 1250 Series modules, as required.

Several of the 1250 Series switch modules are also available in latching versions. A latching switching module will retain its configuration even when power is removed from the 1250 chassis. These switch modules perform electrically the same as the non-latching switch modules that they are based on and use a similar 1250 Series option number. The latching feature is indicated by the presence of the letter 'L' in the option number, e.g. 1250-L30.

The 1250 Series latching switch modules available are as follows:
1250-L12 Latching Relay Actuator Module
1250-L30 Latching 20 Channel Signal Multiplexer
1250-L40 Latching 4 x 4 Matrix
1250-L52B Latching RF Multiplexer

The command codes required to operate the 1250 Series latching switch modules are the same as those required to operate the non-latching versions.
