  • Page 15: Mode Selection Latching Pushbuttons

    Model PDA1500 Logic Level Converter Instruction Manual Mode Selection Latching Pushbuttons There are two latching pushbuttons located on the top of the unit within the enclosure. These are located next to the ON/OFF and H/L labels, inside the terminal connection openings. These pushbuttons are used to enable Cascade Mode and/or Inverter Mode.

  • Page 16: Output H/L Inverter Mode

    Model PDA1500 Logic Level Converter Instruction Manual Output H/L Inverter Mode The H/L latching pushbutton is used to invert the output states. For example, in Normal Mode, when input channels CH1-CH4 detect high voltage, the corresponding output will provide an active high. When high voltage is not detected on an input, the corresponding output will provide an active low signal.

  • Page 18: Operation

    Model PDA1500 Logic Level Converter Instruction Manual OPERATION The PDA1500 High Voltage AC/DC to Logic Level Converter accepts up to four high voltage input signals and outputs a TTL logic (5 V) signal representative of each input’s status (whether high voltage is present or not).

  • Page 19: Cascade Mode

    Model PDA1500 Logic Level Converter Instruction Manual Cascade Mode Cascade Mode is a special operation mode used for the monitoring of high voltage interlocks where one failure causes a failure of all monitoring points further down in the system. Examples of this include the many interlocks on boiler systems, where a single failure can cause a cascade of failures later in the system.

  • Page 20: Inverted Cascade Mode

    Model PDA1500 Logic Level Converter Instruction Manual Inverted Cascade Mode Inverted Mode may be applied to Cascade Mode. When the H/L pushbutton is latched in the recessed position, Inverted Mode is active. The outputs behave using the same logic as in Cascade Mode, but the output states are all inverted.

  • Page 21: Multiple Unit Cascade Mode

    Model PDA1500 Logic Level Converter Instruction Manual Multiple Unit Cascade Mode Cascade Mode logic may be combined across multiple Logic Level Converters to monitor more than 3 alarm outputs (or 4 inputs). When wired together, output four (4) of a Logic Level Converter will monitor input CH4 and CH1 of the next Logic Level Converter wired in series with it.
