PRX99
PRX series
Electronic vibrator stop circuit for NPN/PNP sensors with part-absence alarm. An evolved PRX92 that stops round electromagnetic vibrators or vibratory hoppers via mechanical, inductive, capacitive or optical sensors, adding an absence-of-pieces alarm and a delayed air-blow output.
Supply 115/230 V, with 2 adjustable timed delays 0–12 sec. (T1/T2), absence-piece alarm (red LED, delay 0–30 sec.), EV air-blow output 24 Vcc with 2 sec. delay and opto-isolated inputs.
Description
The PRX99 is an electronic vibrator stop circuit for NPN/PNP sensors with overfull/absence alarm. It can be used to stop round electromagnetic vibrators or electromagnetic vibratory hoppers through mechanical, inductive, capacitive or optical (photocells) sensors with NPN or PNP outputs. The circuit features 2 adjustable timed delays 0–12 sec. for stop and start of the vibrator, plus an absence-piece alarm and a delayed air-blow output.
Application: Controlling overflow of a vibratory chute at the output of a round vibrator; controlling the loading in a round vibrator from a hopper by means of mechanical level indicators; energizing readout photocells; alarm for absence of pieces; delayed air-blow supply.
