The Allen-Bradley 1771-IF Analog Input Module Assembly (Series B) is a 12-bit module which may be used alone or with an input expander module which provides an expansion to the PC system’s analog input capacity. The economy of adding expander modules is in the increased number of slots because operators can use as many as 8 expander modules to give them a total of 64 slots on their I/O. These expander modules are from catalog numbers; 1771-E1, E2, and E3.

 

The 1771-IF series B analogue input module 12-bit assembly measures analog signals at its inputs and then converts that data into a 3-digit BCD or into a 12-bit binary value. It communicates with the analog input module that is located on the I/O chassis backplane. The binary value or BCD from each of the channels is contained in a 16-bit input data word stored in the module’s memory. In addition, operators may use the remaining 4 bits for diagnostic information after the first nominal 12-bit value.

 

The 1771-IF module contains the units of a 12-bit 1771-IFC input module and two 1771-WB field wiring arms. It bears 8-single ended input channels with each module having the same current or voltage range. To use the single-transfer programming, the transmitter mode switch needs to be set to single-transfer mode. There is a block transfer program which moves all words of the 8 channels from the 1771-IF module’s memory to a designated area in the data table in just one scan. Using block transfer means that the module switch needs to be set to the block transfer mode.

 

In its voltage mode, the 1771-IF module has over-voltage protection and it has a continuous current limit in the current mode. Should these limits be exceeded, the module would be damaged. Fortunately, 1500V opto-electrical isolation protects the system from the damage that arises from over-voltage at the inputs of the modules. The 1771-IF series B Analog Input Module assists with fault diagnostics which it detects on power up. Once a fault is detected, the module ceases all communication to the processor and only resumes once the fault has been corrected.
