The Racal Instruments 1260-13 is a 40-channel relay switching module designed for precision signal routing and device control in laboratory and field test environments. Each channel provides independent Double Pole Single Throw (DPST) switching with the ability to join channels for custom relay network configurations. The module supports switching currents up to 2 A per channel and voltages up to 220 VDC or 250 VAC (rms), making it suitable for a wide range of electronic testing and measurement applications.
