Isolex7TM Isolated Switch Modules Models Available ISOLEX7 Isolated Switch Module Product Features ■ Voltage free switch module ■ Alternative to air switch and tubing ■ Full galvanic isolation ■ Use with momentary or latching switch ■ 16 Amp changeover relay output ■ Power up delay for diagnostic testing ■ Switch short circuit protection ■ Onboard LED or optional remote LED The Tempatron Isolex7TM isolated switch modules offer a modern low cost alternative to air switching systems and tubing by using advanced solid state ferromagnetic technology. The devices can be used with a momentary or latching electrical switch, connected by up to 50 metres of earthed cable. They are available in 110Vac and 230Vac versions (or 24Vdc to special order) with a 16 Amp changeover relay output. The sensors pass near zero measurable current through the connected switch and provide full galvanic isolation between the supply and the inputs and outputs. These chassis mounting modules measure only 60mm x 30mm, have an integral 5 second power up delay for diagnostic testing, and an inbuilt safety circuit to automatically de-energise the output if the connected switch wiring is short circuited. An onboard (or optional remote) LED indicates relay status and diagnostic conditions. For isolated switching in electrical systems, as an alternative to air switching All dimensions in mm Connections The unit is set for onboard LED indication To select remote LED indication ‘spin cut' the copper pad marked LED OFF to disconnect the onboard LED. Connect the remote LED to the 2-pin XTLED Molex header (ensuring LED cathode is connected to pin K). Leave in place for momentary (MOM) relay operation (relay energises whilst the connected switch is closed). I2 Cut out for toggle (TOG) relay operation (relay I1 alternately energises/de-energises each time the connected switch is closed and opened). Switch Wiring Diagnostic Test Set the connected switch to off and switch on the power supply to the unit. The LED will illuminate and blink for approximately 5 seconds if the length/capacitance of the switch wiring is within acceptable limits.
