High voltage reed relay switching modules suitable for use right up to 7500 Volts. Model 20-310 contains 16 uncommitted reed relays, available as Normally Open or Changeover. Model 20-320 is a versatile dual 8 to 1 channel multiplexer. These units are designed for both “hot ” switching (close switch after load applied) and “cold ” switching (close switch before EHT load applied) high voltage applications giving reliable switching with no disruption to internal logic. To ensure maximum high voltage isolation, all modules are driven by a separate optically isolated driver module (Model 10-410-003).The driver module is connected to the high voltage unit via a dedicated interconnection cable. All relay coils are sensed to guarantee correct operation
