The 2-channel compact isolators ISpac are equipped with
detachable terminals available in screw terminal, spring cage
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) or simply and conveniently connected to the automation
system using the pac-Carrier.
The pac-Bus supplies the isolators with power and issues line
errors occurring in the Ex i 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 its choice of 8 or 16 slots, the pac-Carrier makes for an elegant
automation system integration solution. Connecting to diverse
automation systems is made easier by system-specific circuit
board adapters equipped with matching plugs.
With the ISpac system also system specific solutions in any
possible constellation from engineering to cabinet manufacturing
are available.
