Isolators at its best - ISpac

  • All standard functions with 2 channels per module

  • Galvanic isolation between inputs, outputs and power supply

  • Modules for DIN-rail installation

  • Detachable terminals available in screw terminal, spring clamp terminal and insulation cutting terminal versions

  • Extended temperature range - 20 °C … + 70 °C

  • Installation also possible in Zone 2 resp. Div. 2

  • Most isolator versions can be used for applications according to „functional safety“ (IEC 61508)

  • Customer specific engineering by R. STAHL's competence center

 Overview of System Components
 Application Non-Ex i Isolators

 

The 2-channel compact isolators ISpac are equipped with detachable terminals available in screw terminal, cage clamp terminal and insulation cutting terminal versions. Depending on the particular application, the devices snap singly onto DIN rails and can either be centrally supplied from the common power supply (pac-Bus).

The pac-Bus supplies the isolators with power and issues line errors occurring in the inputs and outputs via a floating contact. In addition to this collective messaging system, each individual device signals line errors by means of a red LED and an indicator contact.

With the ISpac system also system specific solutions in any possible constellation from engineering to cabinet manufacturing are available.
