Barrier/Switch Isolator
A barrier/switch isolator is designed to supply power to the NAMUR sensor, read the output state of the sensor and provide the desired
safety and switching options based on the sensors current state. The barrier/switch isolator has three sets of connections: the supply voltage (powers the barrier), an input stage (accepts sensor inputs), and an output stage (relay or transistor switching). Supply voltages are 220VAC, 110VAC, or 24VDC. Switch isolators may receive an input from inductive sensors or dry mechanical contacts. The input circuit between the sensor or mechanical contact and the switch isolator is suitable to be installed in a hazardous area under the designation “Intrinsically Safe”. Supply voltage and switching options must be specified when ordering.
