RTD Splitter, Resistance Splitter
DAT4631B
The DAT4631B RTD Signal Splitter is a DIN rail mount, isolated signal conditioner designed to duplicate RTD or resistance inputs into two identical analog outputs. It accepts RTDs (Pt100, Pt500, Pt1000, Ni100, Ni1000) or resistance signals up to 2000 Ω, and provides two independent, isolated voltage or current outputs that are temperature-linearized.
The DAT4631B is ideal for applications where one sensor signal needs to be shared with two different systems — such as a PLC and a recorder — without loss of accuracy or risk of loading effects. Each output is fully isolated from the input, power supply, and from each other to ensure signal integrity and system safety.
Configuration can be performed via PC software or DIP switches, making setup flexible in both factory and field environments. With high accuracy, low thermal drift, and versatile output options, the DAT4631B is the reliable solution for duplicating RTD/resistance signals in industrial automation and monitoring applications.
