The AC 800M controller has an extremely small footprint and a simple DIN rail mounting/dismounting procedure using a unique sliding and locking mechanism. High reliability and simple troubleshooting procedures. Supports S800 I/O high integrity (with PM858, PM862, PM865, PM866A, PM867 and PM891)
CB801 Profibus DP Communication Interface
Profibus DP slave expansion module for Panel 800.
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
