PLC control cabinet-a signal isolator dah

Industrial automation lamah chuan PLC (Programmable Logic Controller) control cabinet te hian hmun pawimawh tak an chang a, sensor leh actuator hrang hrang atanga signal dawngtu te, internal logic operation hmanga production process dik taka control theihna tur te an thawk a ni. Mahse, a taka hmannaah chuan PLC control cabinet-te hian electromagnetic environment complex hrang hrang leh signal interference lama harsatna an tawk fo a, chu chuan control system a tichhe thei a, a chhiat fo thei a, hmanrua leh mipui himna atan pawh a tichhe thei a ni. Chuvangin, adding signal isolated a niators to PLC control cabinets chu solution hman tlanglawn tak a ni ta.

Signal isolator hnathawh ber chu electromagnetic interference transmission venna, system chhiatna thleng tihtlem, leh hmuna hmanrua chhiat a nih chuan isolation pek te, control system pumpuiah fault darh zel tur venna te a ni. PLC-in signal a dawnte chu semiconductor device hmanga modulate leh transforming a, chutah optical emaw magnetic sensing device hmanga isolate leh convert a, a tawpah demodulate leh transforming-in original signal emaw signal hrang hrangah a thlak leh a, he process hian signal chu a stability leh accuracy a tichiang a, chutih rualin PLC chhiatna a veng bawk a, on-site signals-in PLC-a nghawng a neih chu a ti tlem bawk a, a bik takin clutter signal-te chu a ti tlem bawk. Hei bakah hian signal isolator hian signal conversion a ti thei bawk a, chu chu PT10 connection atanga signal lo chhuak chu 4-20mA signal-ah a chantir a, PLC system-ah input a ni a, hei hian electric leh power source inkara buaina awmte chu a tha zawngin a pumpelh thei a, loop leh equipment inkara inthlak danglamna buaina chu a chinfel sak thei bawk.

Steel plant-a production line-a hman tur bikteah chuan PLC, on-site automation instrument, leh on-site actuator hmangin tehna leh control theih a ni. PLC hi hmun atanga metre za tam tak hlaa awm control cabinet-ah dah a ni a (room temperature-a thawk) a ni a, site atanga automation instrument emaw thermocouple emaw te chuan control room chhunga control cabinet chhungah wire hmangin signal an pe chhuak thin. Hetih lai hian PLC chhunga signal lut chu isolated a ngai a, convert a ngai bawk thei a, chu chu 4-20mA isolate a, PLC a luh hmain 0-5V ah convert a ngai bawk. Thermocouple signal isolation leh conversion tifel thei hmanrua chu "thermocouple signal isolator" emaw "thermocouple temperature transmitter" emaw an ti a. A core function-ah hian input signal leh output signal te chu isolate a ni a, chubakah thermocouple atanga input mV level signal chu standard industrial signal (4-20mA, 0-5V, 0-10V) ah a chantir bawk.

A tawi zawngin, signal isolator dah hi industrial automation system rintlakna tihchangtlunna atan te, failure rate tihtlem nan te, PLC hmanrua venhimna atan te, signal quality tihsan nan te a pawimawh hle a ni. Control system-te hnathawh dan nghet leh rintlak taka kalpui theihna tura thil pawimawh tak pakhat a ni
