TU810V1 Compact Module Termination Unit 16-Channel 50V S800 I/O | ABB

The Original New ABB TU810V1 (3BSE013230R1) is a 16‑channel, 50 V compact module termination unit (MTU) for the ABB S800 I/O system. As a passive unit, it serves as the physical wiring interface between field devices and S800 I/O modules, distributing ModuleBus signals to the connected I/O module and to the next MTU in a daisy‑chain configuration. The TU810V1 is designed for compact installations using one‑wire connections, supporting up to 16 channels of field signals and process power connections. It features mechanical keying with 36 possible configurations to prevent incorrect I/O module insertion.

Core Engineering Highlights:
16 field signal channels | 50 V rated insulation voltage | Passive MTU for S800 I/O | 2 A per I/O channel, 5 A process connection max | 2 x 2 process power + 5 x 2 process power (0 V) connections | Mechanical keying (36 configurations) | DIN rail mounting with latching device for grounding | ModuleBus distribution to I/O module and next MTU | Automatic address generation via position signal shifting | IP20 protection | –40°C to +70°C operating temperature
