ISpac isolators: Easy to connect, user-friendly These isolators provide galvanic separation when they integrate field devices in process systems into automation systems. R. STAHL's ISpac isolator range is easy to use and boasts an impressive range of functions and a long service life.

The combination of pac bus and ISpac isolators makes it incredibly easy to connect the auxiliary power supply and read error messages: All you need to do is snap the pac bus and the device onto the DIN rail and the wiring is complete; power is supplied via the DIN rail. Only R. STAHL allows you to install all devices on a DIN rail or in a pac carrier.

All ISpac isolators for analogue signals can transmit HART signals. With a combination of isolators, HART multiplexers and termination boards, these signals can be efficiently transmitted to asset management systems.

Every aspect of our ISpac isolators is designed with functional safety in mind. These products conform to SIL 2 and SIL 3, including devices with trip amplifier function.

  • Compact: Two-channel modules for all functions
  • Time-saving system for wiring: pac bus or pac carrier
  • Broad range of applications: Can be used for SIL applications up to SIL 3
  • HART-capable
