34903A CAL

The 34903A CAL from Keysight Technologies is a 20 channel actuator/general purpose switch module for 34970A/34972A data acquisition/switch units. It has 20 independent single-pole, double-throw (SPDT) relays and is used to cycle power to products under test, control indicator and status lights and to actuate external power relays and solenoids. Combine it with matrix and multiplexer modules to build custom switch systems. Its 300V, 1A contacts can handle up to 50W, enough for many power line switching applications.

• Calibrated actuator/general purpose switch module
• SPDT (form C) latching relay, 120ch/sec speed
• 300V maximum voltage, 1A maximum current, 10MHz bandwidth
• Less than 3µV thermal offset, 50W power rating
• Less than 0.2ohm initial closed channel, greater than 10Gohm isolation (ch to ch, ch to earth)
• 120/s open/closed speed
• Operating temperature range from 0°C to 55°C
