Direction Discrimination Unit HU-101

It determines the direction of passage for people and vehicles using a two-way function.

■Two-way function for direction detection Using two sensors to detect people and vehicles, the direction of passage is determined by the two-way function. ●Forward detection When a person or vehicle is detected in the order of Sensor 1 → Sensor 2 within a certain time, a forward sound is emitted, and a forward output is activated for the timer duration. ●Reverse detection When a person or vehicle is detected in the order of Sensor 2 → Sensor 1 within a certain time, a reverse sound is emitted, and a reverse output is activated for the timer duration. ■Distinction between people and vehicles possible with AND detection of two sensors In addition to the conventional direction detection timer, the AND detection condition of Sensor 1 and Sensor 2 (detecting Sensor 2 while Sensor 1 is detected) allows for the detection of vehicles (wide objects) only. *When settings other than AND are used, simultaneous input will activate the forward output. ■Control of AC100V devices possible with large contact output In addition to small contacts, the forward output includes a large contact output (AC100V 5A resistive load), allowing direct operation of alarms such as rotating lights.
