Introduction i-on RangePage 2Printed Circuit BoardAll of the control unit functions and connectors are provided by a single PCB. In the i-on30EX/i-on30EXD, i-on30EXL/i-on30EXDL, i-on50EX/i-on50EXD and i-on160EX aplastic PCB carrier holds the PCB within the case.Bus Connections30 50 160.The i-on EX range of control units provide connectors for one four-wire bus cable. Allkeypads, expanders and other equipment connect to the same bus. The cable can be runas one single line, or as a three or four armed star branched at the control unit. See therelevant Installation Guide for details of bus configuration, maximum bus length andcabling type.Zone ConnectionsThe control unit itself provides the following connections for wired zones:Control Unit CC Zones FSL Zonesi-on40 8 x 4-wire 16 x 2-wire 16i-onEX 5 x 4-wire 10 x 2-wire 10These zones can be either all Closed Circuit (CC) or all Fully Supervised Loop (FSL). TheInstaller can select the zone wiring type during initial commissioning, or at any time after.The Installer can make the wiring type of expanders either CC or FSL, independent of thewiring type of the zones on an i-onEX control unit. Note that there are no wired zones onthe i-on16 control unit.Output ConnectionsTransistor OutputsThe control unit provides connectors for programmable transistor outputs which can beused to control external equipment. The outputs are normally switched negative, from 12Vto 0V on activation. In this mode each output can sink up to 500mA from a dc source.The installer can program these outputs to be switched positive (from 0V to 12V onactivation). In this mode the outputs can deliver up to 500mA to an external load.See page 9 for the number of transistor outputs available on each control unit.Relay Outputs40 50 160.The i-on40, i-on50EX and i-on160EX control unit also provide sets of connectors for relayoutputs, providing voltage free changeover contacts. Relay outputs are programmable bythe Installer.See page 9 for the number of relay outputs available on each control unit.Digital Communicator Outputs (Plug-by Outputs)30 40 50 160.A set of pins on the control unit PCB provide programmable outputs designed to control aseparate digital communicator.By default each output is switched negative (switched from +12V to 0V when active).When at 0V each communicator output can sink up to 100mA.The installer can program these outputs to be switched positive when active (switchedfrom 0V to +12V). When at +12V each output can provide up to 50mA to an external load.
