8851-LC-MT

What does this controller do in an industrial system?

It is a SafetyNet logic controller designed for logic control duties in applications that require an SIL 2-rated safety function, coordinating I/O and network communications as part of a PAC8000-based architecture.

What supply voltage does it require?

It operates from a 12 V DC supply.

How is it mounted in a control panel?

It is designed for DIN rail mounting, making it suitable for standard industrial enclosures and cabinets.

Can it be used in redundant controller arrangements?

Yes. It supports redundancy configurations (including duplex operation) to increase availability, with bumpless transfer behaviour intended to minimise process disruption during controller role changes.

What network connectivity does it provide?

It provides dual-redundant high-speed Ethernet connections for robust communications within the control system.

Does it support controller-to-controller communications?

Yes. It supports peer-to-peer communications between controllers for exchanging data within the control architecture.

What kind of applications is it commonly used for?

It is commonly used where an SIL 2-rated logic solver is required, such as burner management and combustion safeguards, machinery and process interlocks, emergency shutdown (ESD) functions, and other industrial permissive/trip logic schemes.

Is it suitable for hazardous location installations?

It carries hazardous location approvals including Class I, Division 2 (Groups A, B, C, D) with Temperature Code T4, and ATEX II 3 G (Ex nL IIC T4), subject to installation practices consistent with the relevant control drawings and site requirements.

Which functional safety standard is it assessed against?

It is assessed as suitable for safety-related applications up to SIL 2 in line with IEC 61508 (with additional related standards referenced for industrial use cases).

Can it be used as a standalone controller or only within a wider PAC8000 system?

It is intended to operate as part of a PAC8000 system, working alongside compatible I/O and network components within that platform.

Are there any key compliance standards associated with this controller?

Yes. Typical referenced compliance frameworks include FM, CSA, and ATEX requirements for industrial/hazardous environments, plus functional safety and industrial control standards such as IEC 61508 and IEC 61131-2 (as applicable to the installation and overall system design).

What should I check to confirm it fits my cabinet design and electrical design?

Confirm 12 V DC power availability, DIN rail space, the intended network topology (including use of dual Ethernet paths), and whether the installation environment requires Class I Div 2 and/or ATEX compliance. If you are matching an existing installation, verify the system architecture (simplex vs duplex) and the surrounding PAC8000 modules used with it.
