Isolators / Distributors
LU-G22 Analog Signal Isolation Processor/Distributor (2 In / 2 Out)
The LU-G22 two-input, two-output analog voltage/current signal isolator and distributor connects field two-wire transmitters, DC voltage sources and DC current sources, isolating and converting their 4-20mA/1-5V analog signals before transmission to control systems or other modular instruments. It uses an independent DC supply with isolation between power supply, input and output, and the two channels are independent and isolated from each other.
