PDA1500 High Voltage to Logic Level Converter


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.

Cascade mode is ideal for monitoring signals that can result in cascading or subsequent failures. This mode monitors the point of failure when a failure in a single input causes a failure in all alarm points in a “series” system.

The PDA1500 is mounted in an ABS plastic DIN rail mounted enclosure for easy mounting inside a panel or instrument enclosure.
