Millivolt inputs

The T8840 allows a block of eight channels of a T8431 to be connected to thermocouple, RTD or other

millivolt inputs using plug-in converters. It requires a VFTA cable TC-211, 212, 511 or 512, which

provides separate plugs for each group of channels. This can be wired via a VFTA T8842 allowing

some channels of the module to be used for current loops. Configuration options are given in PD-8840.

The T8841 is similar to the T8840 but is specially designed for RTD inputs.
