Product Description

Overview

The Bachmann SLC284 is a high-performance safety processor designed for mission-critical automation systems requiring the highest safety integrity. Fully compliant with IEC 61508 SIL3 and ISO 13849 PL e / Cat 4, this module executes independent safety logic while seamlessly integrating with Bachmann M1 and M200 controllers. It offers scalable, distributed safety I/O management for complex industrial applications.

Key Features

Dual-Processor Architecture: Equipped with two independent 32-bit microcontrollers operating at 72 MHz, ensuring cross-checked, fail-safe operation.

High-Speed Safety Execution: Minimum cycle time of 5 ms for rapid emergency response.

Decentralized I/O Support: Connects with remote safety I/O modules such as SDI208 and SDO204 via FASTBUS, CAN, or bluecom, with distances spanning several hundred meters.

Redundant I/O Capability:

• 16 digital inputs (up to 8 redundant pairs)

• 8 digital outputs (0.5 A per channel, 4 redundant pairs supported)

Electrical Isolation: 500 V galvanic isolation between system and I/O for electrical safety.

Operating Modes: Easily switchable between SAFE, PROG, TEST, and ERROR modes with clear LED indicators.

Safety Programming: Program and configure via Bachmann SolutionCenter, with independent serial programming interface or direct controller access.

FAQ

Q: Can SLC284 integrate with standard PLC logic?
A: Yes, it operates independently for safety logic while exposing I/O states to the standard PLC for diagnostics.

Q: What is the maximum distance for decentralized I/O modules?
A: Remote safety I/O modules can be connected over several hundred meters via FASTBUS, CAN, or bluecom.

Q: Is the module suitable for extreme temperature environments?
A: Yes, the ColdClimate (CC) version supports low-temperature operations typical in wind turbines and outdoor installations.

Q: Can digital outputs be used redundantly?
A: Yes, outputs can be paired for redundant SIL3/PL e applications.
