The PDA1500 High VAC/VDC to Logic Level Converter is an easy to use DIN rail mounted device for converting high voltage signals into logic level signals for use as a digital input to a wide range of process control and display equipment.
The PDA1500 accepts up to four high voltage AC or DC signals. The PDA1500-115's inputs accept 85-130 VAC or VDC, and the PDA1500-230's inputs accept 185-265 VAC or VDC. Powered from 12-24 VDC, the PDA1500 can drive outputs even when no high voltage inputs are present. The outputs are user selectable for high or low states when voltage is present at the inputs.
- Combine with the vigilante II annunciator to monitor high voltages
- Four high voltage inputs - Up to 265 Vac or Vdc
- Four 5 Vdc digital outputs
- Easy DIN rail mounting
- Simple two-button setup
- Cascade mode for series break configurations
- Multi-Unit cascade mode
Approvals & Certifications
- IEC Ex
Enclosure, Body Material
- ABS Plastic
- Two latching pushbuttons for selection of output state inversion and cascade mode selection. No other programming required.
- One green power LED. Four red LED indicators to monitor live inputs on channels 1-4. Two yellow LED indicators for inverted output and/or cascade output mode.
- Four independent, isolated input channels CH1 to CH4
Input Voltage Threshold
- Input high voltage levels are different for AC and DC voltages. Instantaneous value is used to determine threshold for AC input - RMS equivalents are shown below.
PDA1500-115Input High Threshold Range
- 60 VAC RMS (85 VAC peak) or 85 VDC
Input Low Threshold Range
- 31 VAC RMS (44 VAC peak) or 44 VDC
PDA1500-230Input High Threshold Range
- 131 VAC RMS (185 VAC peak) or 185 VDC
- 1.2 mA (typical) at "turn-on" or high input voltage
- Input Propagation Delay to Logic Low: 4 µs (typ); 15 µs (max); Input Propagation Delay to Logic High: 8 µs (typ); 40µs (max).
- PDA1500-115: >60kΩ total impedance per channel; PDA1500-230: >140kΩ total impedance per channel.
