PDA1500 High Voltage to Logic Level Converter

General

Configuration Method: Two latching pushbuttons for selection of output state inversion and cascade mode selection. No other programming required.
Indicators: 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.
Input Channels: Four independent, isolated input channels CH1 to CH4

Inputs feature high common mode rejection, ideal for noisy environments.
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
PDA1500-230 Input High Threshold Range: 131 VAC RMS (185 VAC peak) or 185 VDC
Input Low Threshold Range: 66 VAC RMS (94 VAC peak) or 94 VDC
Input Current: 1.2 mA (typical) at "turn-on" or high input voltage
Propagation Delays: Input Propagation Delay to Logic Low: 4µs (typ); 15µs (max); Input Propagation Delay to Logic High: 8µs (typ); 40µs (max).
Input Impedance: PDA1500-115: >60kΩ total impedance per channel; PDA1500-230: >140kΩ total impedance per channel.
Input Overload: Must not exceed 50 mA DC (35 mA RMS) on input channels. Maximum input power dissipation is 230 mW. Surge protection included for up to 140 mA. Transient protection included for up to 500 mA.
Digital Outputs: Four TTL Logic (5V) independent digital outputs.
Output Logic Levels: Output Low: 0 to 0.33 V Output High: 4.4 to 5.0 V
Cascade Mode: Typically used in Boiler applications to monitor for and detect fault conditions.
Power: 12-24 VDC + 10%, 1.5 W max. Polarity sensitive. Short-circuit protected. Isolated.
Max Power Dissipation: PDA1500-115: 3W (total dissipation of unit) PDA1500-230: 4W (total dissipation of unit)
Isolation: 630 VRMS between input channels; 3750 VRMS input-to-power line; 3750 VRMS input-to-output; 1000 VRMS output-to-power line
