Key features

  • Provides an IS-compatible mechanism to separate two sections of the backplane allowing IS and non-IS field-device wiring to the same I/O group.
  • Converts hazardous power to IS-safe power to run one side of the bus receiver/transmitter circuitry and IS-safe FLEX Ex backplane power to slave side modules.
  • Allows up to eight FLEX Ex modules may be attached to the slave side.
