Features:
- Provides a High-Resolution Analog Interface Between Field Devices and the 1771 I/O Rack Backplane
- Unites 1000 Volt Channel-to-Channel Isolation with Open Input and Open Loop Detection Capability
- Coordinates with PLC-5 Processors and Standard N-Series Analog Modules
The Allen-Bradley 1771-NOV N-Series Analog I/O Module operates as the high-resolution isolated analog module in a 1771 I/O rack, providing precise analog signal conversion and 1000 Volt channel-to-channel isolation to all connected modules within the system. It continuously processes incoming analog field signals at 1.32 milliVolts per bit resolution and transmits this high-accuracy data through the rack backplane to support steady state operation of all control and monitoring modules.
The 1771-NOV provides essential analog I/O functions common to the entire rack, and is a critical component of the signal conversion path, directly affecting the proper, normal operation of the overall analog control system. One 1771-NOV module is utilized per analog slot depending on the desired channel configuration.
For isolated analog channel applications, the 1771-NOV system requires proper utilization of its internal 1000 Volt isolation barriers. In addition to standard signal conversion operation, the 1771-NOV also performs continuous open loop detection for thermocouples, RTDs, voltage inputs, and current loops. The 1771-NOV channel architecture executes signal protection using the internal isolation barriers specified in the module design.
The 1771-NOV Allen-Bradley N-Series Analog I/O Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
