3BSE013208R1 ABB TB820V2 Modulebus Cluster Modem

3BSE013208R1 is the ABB TB820V2 ModuleBus Cluster Modem, part of the S800 I/O communication interface range.

The TB820V2 provides an interface between the electrical ModuleBus used by local S800 I/O modules and the optical ModuleBus used to distribute I/O clusters. The electrical and optical sides are logically part of the same ModuleBus, allowing the I/O architecture to be extended beyond a single local group. ABB specifies support for up to 12 I/O modules on the electrical ModuleBus and up to 7 I/O clusters on the optical ModuleBus.

This makes the TB820V2 particularly relevant when an S800 I/O station needs local optical distribution or more I/O capacity than can be accommodated on one electrical ModuleBus segment.

ABB's current product selector identifies 3BSE013208R1 as the TB820V2 article number and specifies the device as a ModuleBus slave without line or module redundancy.

The TB820V2 is more than a generic communication modem. Its purpose is to provide the optical cluster interface for S800 I/O ModuleBus.

On the local side, the device connects to S800 I/O modules through the electrical ModuleBus. On the optical side, it provides two fiber-optic ports for the optical ModuleBus.

According to ABB:

• Up to 12 I/O modules can be connected to the electrical ModuleBus.
• Up to 7 I/O clusters can be connected through the optical ModuleBus.
• The optical interface is intended for local distribution of I/O clusters.
• It is also useful where an I/O station requires more than 12 I/O modules.

The TB820V2 also includes supervisory functions for the ModuleBus and power supply, together with an isolated power supply for connected I/O modules.

The optical side is one of the defining characteristics of TB820V2.

ABB's current product catalog specifies a maximum of seven optical I/O clusters and a 650 nm optical wavelength. For local optical connections, ABB lists maximum cable lengths of 15 m for Plastic Optical Fiber (POF) and 200 m for Hard Clad Silica (HCS).

The TB820V2 therefore fits applications where I/O clusters need to be distributed locally rather than all installed directly beside the main controller/interface.

ABB's System 800xA product catalog provides these electrical values specifically for article number 3BSE013208R1.

The 170 mm height includes the module latch according to ABB's current product selector.

 

 

Environmental Conditions

 

Parameter	Specification
Operating Temperature	0 to +55 °C
Maximum Ambient Temperature, Vertical Mounting	+40 °C
Storage Temperature	-40 to +70 °C
Relative Humidity	5–95%, non-condensing
Pollution Degree	2
Corrosion Protection	ISA-S71.04 G3
Protection Class	IP20

 

ABB notes that approvals are issued for an operating temperature range of +5 to +55 °C, while the product data lists 0 to +55 °C operating temperature. Vertical mounting has a lower maximum ambient temperature of 40 °C.

TB820V2/TB820 uses a rotary switch to select the cluster number from 1 to 7 on the optical ModuleBus. This corresponds with the maximum of seven I/O clusters supported on the optical side.

This feature is particularly useful when several distributed S800 I/O clusters are connected through the optical ModuleBus and each cluster needs its own identification within the architecture.

ABB's earlier System 800xA catalog identifies TB820V2 3BSE013208R1 as a non-redundant optical cluster modem and specifies that the package includes:

• 1 × Power Supply Connector
• 1 × TB807 ModuleBus Terminator

The TB807 is therefore worth retaining as a related accessory/reference when customers are checking the original TB820V2 assembly.

The following products are more useful as related products than generic ABB communication modules:

The distinction is useful for procurement: TB820V2 and TB840A are cluster modem products, whereas TB825/TB826 are primarily optical media converters and TB842 serves as a ModuleBus optical port. ABB's current catalog separates these functions clearly.

For internal linking, I would prioritize TB840A, TB825, TB826 and TB842 only when those product pages actually exist on your site.

A simple way to understand the product relationship is:

S800 I/O → Communication Interfaces → ModuleBus → TB820V2 → Optical I/O Cluster Distribution

The TB820V2 does not function as an ordinary I/O channel module. Its role is to provide the communication path between the local electrical ModuleBus and distributed optical ModuleBus clusters.

That distinction is important for customers searching for 3BSE013208R1 because searches for "S800 I/O module" can otherwise lead to individual DI, DO, AI or AO modules rather than the communication interface they actually need.

What is 3BSE013208R1?
3BSE013208R1 is the ABB article number for the TB820V2 ModuleBus Cluster Modem used with the S800 I/O system.

What does the TB820V2 do?
TB820V2 provides an electrical-to-optical interface for the S800 I/O ModuleBus, allowing local I/O modules and distributed optical I/O clusters to communicate through the same ModuleBus architecture.

How many I/O modules can be connected to the electrical ModuleBus?
ABB specifies a maximum of 12 I/O modules on the electrical ModuleBus.

How many clusters can TB820V2 support?
Up to 7 I/O clusters can be connected through the optical ModuleBus.

Does TB820V2 support redundant operation?
No. ABB identifies TB820V2 as a non-redundant module. The redundant cluster modem in the same product group is TB840A.

What is the power supply for 3BSE013208R1?
The TB820V2 uses a 24 V DC power input, with an allowable input range of 19.2–30 V DC.

What fiber connection does TB820V2 use?
The TB820V2 provides two optical ModuleBus ports. ABB specifies support for local Plastic Optical Fiber (POF) and Hard Clad Silica (HCS) connections.

Is TB820V2 an S800 I/O input or output module?
