Series system.This intelligent device enables part of the Signature data loop to continue operating should a short circuit occur.The Fast Stable Communication-Built-in intelligence means less module can be wired into a Class A data loop at any point. information needs to be sent between the module and the loop controller.Other than regular supervisory polling response,the If a fault occurs,the isolator cuts power to all devices beyond the module only needs to communicate with the loop controller isolator on the loop as follows: when it has something new to report. • a short on the line causes all isolators to open within 23 msec. • at 10 msec intervals, beginning on one side of the Class A Standard Features circuit nearest the loop controller,the isolators close to provide the next isolator down the line with power. • Automatic device mapping • when the isolator next to the short closes,it reopens within Each module transmits wiring information to the loop 10 msec. controller regarding its location with respect to other devices on the circuit.
