Configured for binary status acquisition and signal monitoring in ABB Relion protection and control systems, the ABB 1MRK000284-AB (1MRK000284 Binary Input Module) provides direct electrical interfacing between field contacts and Intelligent Electronic Devices (IEDs). The module transfers discrete operating states from switches, pushbuttons, protection contacts, and auxiliary devices for real-time supervision and control functions.

Product Identification

Hardware Specifications

Firmware Flash Compatibility

The 1MRK000284-AB operates as an interface board within ABB Relion protection architectures. Firmware compatibility is managed at the host IED level rather than within the binary input board itself. During maintenance activities, replacement boards should match the installed hardware revision and approved relay firmware release to maintain correct signal mapping and event processing.

The module supports I/O density scaling by allowing additional binary status points to be integrated into protection and control schemes. Typical monitored signals include breaker positions, transformer alarms, motor permissives, auxiliary contacts, and interlocking conditions.

Technical FAQ

Q: Does the 1MRK000284-AB directly process analog signals?
A: No. The module is designed for binary or discrete input status acquisition and does not perform analog measurement functions.

Q: Is galvanic isolation provided between field wiring and internal electronics?
A: Yes. The module incorporates galvanic isolation to separate field-level signals from control circuitry.

Q: Can the module monitor circuit breaker auxiliary contacts?
A: Yes. Breaker open/close indications are typical binary input applications within protection and control systems.

Q: Is hot-swapping supported while the host relay remains energized?
A: Hot-swap capability is determined by the host Relion IED design and maintenance procedures. Follow ABB equipment-specific service instructions before removal or installation.

Q: What types of field devices can be connected to the module?
A: Typical sources include selector switches, pushbuttons, auxiliary relay contacts, alarm contacts, position switches, and other discrete signaling devices.
