prh-ZG4 Random generator

PRH-ZG4 is used as person check (e.g. coworker drawing) and passage check.

The power pack for 230V~ is already inserted. It supplies the digital logic and the inserted pictographs “green” and “red“ as well as the acoustic signal generator and two pilot relays for the passage check.

Housing
prh-ZG4 is accommodated in a very sturdy insulant housing (enclosure IP65).
W x H x D: approx.13,5cm x 18,5cm x 9,5cm

Power Supply
prh-ZG4 must be supplied with 230 V of alternating voltage and takes up max. 16VA.

Outputs (back relays)
As outputs for “red” and “green” in each case separated two-way back contacts are available. The poles are attached to altogether six internally accessible spring action clamps.

Displays
Red cross: The output relay “red” is active.
Green arrow: The output relay “green” is active.
Specially bright LEDs are used under a sun visor.
The volume of the acoustic signal generator is adjustable by an internal potentiometer.

Timer
Green = uncontrolled passage, the duration of this status can be adjusted in 10 levels between 0,15s and 9s.
Red = passage to be controlled, the duration of this status can be adjusted in 9 levels between 0,3s and 8s.
Furthermore ZG4 can be configured to an external reset contact for the termination of the duration of status „red“.

Random Rate 0,5% … 50%
The rate of persons to be controlled is digitally adjustable in 1% steps between 0,5% and 50%.

Software
Since the complete development authority is in our house, also special wishes can be fulfilled easily.
