Product:Allen-Bradley 1756-IF16

Non-isolated Analog Voltage/Current Input Modules

The 1756-IF16 and 1756-IF8 modules alert you when a signal wire only has been disconnected from one of its channels or the RTB has been removed from the module. When a wire-off condition occurs for this module, two events occur:

• Input data for that channel changes to a specific scaled value.

• A fault bit is set in the owner-controller that can indicate the presence of a wire-off condition. Because the 1756-IF16 and 1756-IF8 modules can be applied in voltage or current applications, differences exist as to how a wire-off condition is detected in each application.

The Channel Status word has these differences when the 1756-IF16 module is used in integer mode.

• Only Underrange and Overrange conditions are reported by the module.

• Alarming and Calibration Fault activities are not available, although the Calibration Fault bit in the Module Fault word activates if a channel is not properly calibrated.

• There is one, 32-bit Channel Status word for all 16 channels.
