Key Features
The AFV10D-S41201 offers several advantages for process control applications.
Dual-Redundant Architecture:
The unit features dual-redundant Vnet/IP and dual-redundant power supplies. Consequently, system availability is maximized for critical processes.
Hot-Swappable Modules:
Processor and power supply modules can be replaced without shutting down the system. Therefore, maintenance does not interrupt production.
Battery-Backed Memory:
Main memory is protected for up to 72 hours during power failure. Hence, process data and programs are not lost.
ESB and ER Bus Support:
Connects to both ESB and ER bus node units. Thus, it supports a wide range of I/O modules.
Fault Contact Output:
Provides a dry contact that opens during FCU failure. As a result, external alarm systems can be triggered.
19-Inch Rack Mountable:
Standard form factor fits into existing industrial racks. Consequently, integration into new or existing systems is straightforward.
LFS1500 Control Function:
Includes LFS1500 for Field Control Station operation. Therefore, it is ready for advanced process control strategies.
Typical Applications
The AFV10D-S41201 suits various process control applications.

Installation Guidelines
Install the AFV10D-S41201 in a 19-inch rack using 8 x M5 screws. Use the supplied insulation bush accessories. Ensure the rack is properly grounded.
For dual-redundant configuration, install two processor modules (CP451) and two power supply modules (PW481, PW482, or PW484). Install EC401 modules in both slot 7 and slot 8 for ESB bus communication. For ER bus, install EB401 in an odd-numbered slot.
Connect the power supply using M4 screw terminals. For 100-120 V AC, the consumption is 200 VA. For 220-240 V AC, consumption is 230 VA. Connect the Vnet/IP network using CAT5e or better UTP cable to a Layer 2 switch.
The FCU status contact output provides NC/C contacts. These contacts open during FCU failure. Connect these to an external alarm system.
