JA100-BUS 120Z

JA-120Z Bus back-up booster unit for JA-100

Designed for current boosting of the bus, extension of the line length and galvanic isolation of the bus. Output current max. 2A. 2 independent bus output terminal boards – each providing 500 m of bus length.

The product is offered as an electronic module with the JA-83PWR power supply unit. We recommend installation in a PLV-CP-L plastic housing. The product is a component of the JABLOTRON 100+ system, is addressable and occupies one position in the system.

  • Output current max. 2A
  • 2 independent bus output terminal boards – each providing 500 m of bus length
  • The galvanic isolation of the output terminals deals with different ground potentials and safety isolation of the bus
  • Up to 3 boosters can be arranged in series
  • Back-up battery up to 18 Ah
