Performance and Operation

The 1769-BOOLEAN allows users to create flexible Boolean expressions that control outputs based on True/False conditions. When the expression evaluates to True, the output turns ON, and when False, the output turns OFF. With a closed-loop time of 1 microsecond, the module ensures quick response times. Additionally, the module supports input delays as low as 10 microseconds.

Power and Voltage Details

Operating on 24V DC input and output, the 1769-BOOLEAN draws a maximum of 220 mA at 5.1V. It features an isolation voltage of 75V DC and is tested to withstand 1200V AC for 1 second or 1697V DC for 1 second during dielectric tests. These characteristics ensure both safety and reliability in demanding environments.
