3BSE053240R1 | PM891 | AC800M Communication Interface Controller Module

Redundancy function: PM891 supports redundant configuration and can be used as the main controller or hot standby mode.
Other features:
Integrated Real Time Clock (RTC).
LED indicator lights are used for status monitoring.
Support modular design for easy expansion and maintenance.
ABB 3BSE053240R1 PM891 is a high-performance and highly reliable central processing unit module suitable for various complex industrial automation scenarios. Its powerful computing power, flexible communication interface, and redundant design make it a core component of industrial control systems.

Some of the benefits of the AC 800M Controller are:

• Flexibility, the AC 800M Controller can be ordered as individual units which may be mounted in accordance with the customers own requirements.
• Extremely small footprint.
• Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism.
• Modularity, allowing for step-by-step expansion. You only pay for what you require at the present time.
• Reliability and simple fault diagnosis procedures.
• Controller redundancy for higher availability (CPU, CEX-Bus, communication interfaces, S800 I/O).
• Built-in redundant Ethernet Communication ports.
• Built-in RS-232C communication ports.
• Low power consumption, thus no external fans required.
• Flexible process connection, using either local I/O or standard fieldbuses.
• S800 I/O redundancy.
• Supports S800 I/O High Integrity (with PM858, PM862, PM865, PM866A,PM867 and PM891).
• The major features of the AC 800M are:
• High performance and large application memory.
• Extensive availability.
• CPU redundancy(PM858/PM861/PM862/PM864/PM865/PM866/PM867/PM891).
• AC 800M High Safety Integrity Level 2 certified using PM865/SM810/SM811 or PM867/SM812.
• AC 800M High Safety Integrity Level 3 certified using PM865/SM811 or  PM867/SM812.
• Built-in redundant Ethernet channels.
• Built-in RS-232C channels.
• Sectioned CEX-Bus using a pair of BC810 / BC820.

• Quick and simple fault-finding with the aid of LEDs on each unit / channel.
• Built-in battery back-up of memory (except for PM891).
• External battery back-up.
• Use of industry standard power supply voltage – 24V d.c.
• Easy mounting on standard DIN rail.
• IP20 Class protection without the requirement for enclosures.
• Incorporation of a wide variety of communication possibilities.
• Hardware based on standards for optimum communication connectivity(Ethernet, PROFIBUS DP).

• Support for PROFIBUS DP fieldbus.
• Support for FOUNDATION Fieldbus.
• Support for Advant Fieldbus 100.
• Support for Modbus TCP
