1. To next PL Anet device or terminator Wiring the logic outputs Tne 7way output terminal block provides four logic output connections Pins 5 to 7 G are used as the common return ground One wire can feed this ground to a bank of indicators or other devices The output works by switching the internal 5V reference supply through a 470 ohm resistor to the pin This presents a positive voltage when the output is turned on and an open circuit when it is turned off The switching is done using a transistor The resistor limits the current to a maximum 10mA to ensure the connected equipment does not draw more than the PL 8 can provide The output may be used in many ways to satisfy a range of interfacing applications It is important that the installer has a good working knowledge of interfacing circuits Incorrect application may result in damage to the equipment Typical applications include powering an LED indicator and switching solid state low current relays LAMPS MOTORS EQUIPMENT This product complies with the European Electromagnetic Compatibility directives 89 336 EEC amp 92 31 EEC NOTE Any changes or modifications to the equipment not approved by Allen amp Heath could void the compliance of the equipment Whilst we believe the information in this guide to be reliable we do not assume responsibility for inaccuracies We also reserve the right to make changes in the inter2. Refer to the Help file for details on programming the PL functions Diagnostics fa fault is suspected check the two diagnostics LEDs on the underside of the PL 8 connector PCB Both the red and green LEDs should be lit once communication with the iDR is established If a fault is found first check for correct wiring If further assistance is required contact Allen amp Heath technical support Wiring terminals Phoenix type screw terminal connectors are used for connecting the external switches and logic to the PL 8 Make sure the wire ends are carefully stripped and inserted into the terminals Tighten the screws using a small slotted screwdriver To ensure interference free operation we recommend you use shielded cable Wiring the switch closure inputs The 7way input terminal block provides 4 switch input connections Pins 5 to 7 G are used as the common switch ground One wire can feed this ground to a bank of switches Two switches are shown wired in the diagram here The switch works by linking its connector pin to any ground G pin Use a contact closure such as a momentary press switch microswitch or relay to do this Low current switches may be used We recommend good quality sealed components for reliable operation The input pin is fed from the internal 5V reference supply through a 1k5 ohm resistor It uses an opto coupler to isolate the PL 8 from the connected equipment Approximately 1 2mA minimum current flows wh

ALLEN amp HEATH PL 8 Logic Controller AP5270 For PL 8 units manufactured after November 2004 User Guide The PL 8 is part of the Allen amp Heath PL Series of wall plates and remote controllers available for the iDR 4 and iDR 8 audio mix processor systems It is a small module comprising two circuit cards This can be locally mounted in a single unit wall box using the standard UK EU or US face plate supplied The PL 8 provides four contact closure switch inputs and four transistor logic outputs for external equipment control Their function is programmed using the iDR System Manager software The combination of switch input and logic output makes the PL 8 ideal as a multi function remote controller in installed systems The unit can interface to a variety of devices including alarm systems room divider switching paging controls event triggers and various custom switches and indicators Control can be distributed where it is needed The PL 8 interfaces via the Allen amp Heath PL Anet serial network Multiple PL 8 units can be daisy chained using CAT5 cable along with other PL Anet devices such as the PL 3 and PL 4 wall plates PL 6 fader controller and so on For information on the full range of PL products available visit our web site http www allen heath com i Internal view shown ALARM OVERRIDE ALLENGHEATH gt PL Anet EE E EEEE OC CBABCCCC 0 e 5 AUDIO ROOM DIVIDER S
