ASCO 34900049 - Series 349 Diaphragm Pressure Switch, NC

ASCO Joucomatic pressure switch/pressure sensor detects pressure rates electronically. The signal at the switching output changes as soon as the switching threshold is reached. A digital output (PNP switching output for connection to PLC) and an analogue output with a voltage proportional to the inlet pressure is standard. The switch-on and switch-off points can be adjusted independently. The switching threshold and hysteresis can be adjusted very precisely by means of two potentiometers. The switching status is indicated by LED. The PNP output switches to +24 V as soon as the switching threshold P2 is reached (increase of pressure at the input). The PNP output switches back to 0 V only when the pressure falls below the switching threshold P1. ASCO Joucomatic reference 34900001
