MTL4755ac for 3-wire RTDs.

The MTL4755ac is a 3-channel barrier designed particularly for use with 3-wire RTDs with earthed or floating bridges. As each loop

generally needs three barrier channels, a single module interfaces with one 3-wire RTD. It has a low end-to-end resistance of only

18Ω/channel to minimise span changes while two of the channels track within 0.15Ω (from –20 to +60°C) to minimise zero shift with

temperature. It is not designed to accept bussed power.
