3 Isolators 3/1 Automation 17.04.2008 07509E00 Isolators General �œ Inputs or outputs intrinsically safe [Ex ia] IIC �œ All functions with 2 channels per module �œ Galvanic isolation between inputs, outputs and power supply �œ Modules for DIN-rail installation or comfortable system integration via pac-Carrier �œ Detachable terminals available in screw terminal and spring cage terminal versions �œ Extended temperature range - 20 °C … + 70 °C �œ Installation possible in Zone 2 resp. Div. 2 �œ Most isolator versions can be used for applications according to „functional safety“ SIL (IEC 61508) �œ Customer specific engineering by R. Stahl’s competence center �œ macros for easier planning and engineering available 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.
