The TMxxxxAP series isolation amplifier modules have a
mV-level
positive and negative signal input and positive signal output. These
modules, with a high efficiency micro-power source built-in, can provide power for signal processing circuit. In the three-wire and four-wire
transmitter applications, our products make customers
’
design simple and helpfully improve the room-using ratio of PCB. Adopting
electromagnetism isolation technology, it is available to keep higher accuracy and extremely lower temperature drift than photocoupler
isolation. These modules have three-port isolation (input, output and power supply),and the isolation voltage between them is up to
2.5kVDC.
