TV928  Buffer Amplifier for HART Positioner
  • Inherently safe output ignition protection type [EEx ib]
  • Galvanic separation between input, output and power supply
  • Low loss rating
  • Low input voltage
  • Simple projection
  • EMC protection according to latest NAMUR recommendations, standards and laws
  • LED as operating display
  • Energy supply  AC/DC 24 V
  • Unit width 4 TE

The TV928 barrier is used as a periphery unit for process control systems or regulators. The TV928 carries out the separation of the non-safe area of the maintenance instrumentation to the inherently safe instrumentation of actors in the field area. In addition, an impedance change is carried out, i. e. the output of the process control system is only loaded with a very small impedance.
