85M-6810-T: 8 TCs
The 85M-6810-T module provides 8-channel TC which features high density I/O with a flexible topology and
hot-swappable functionality. This module is cost-effective solution for most industrial application.
Block Diagram
The following is the 85M-6810-T module’s block diagram. The 85M-6810-T uses an MCU processor that has
three communication interfaces: SPI, RS-232, and USB. Whereas the 85M-6810-T module communicates with
the modular head through RS-232 and USB interfaces. The 85M-6810-T has isolation protection up to 3K VDC
or 2K Vrms.
