Product Description
The Allen-Bradley 1771-IL is an analog input module for the PLC5 platform, featuring eight isolated differential input channels that accept voltage signals (1-5V, 0-5V, -5 to +5V, -10 to +10V, 0-10V DC) and current signals (4-20mA, 0-20mA, -20 to +20mA). It converts these signals to digital values ranging from 0-4095 for unipolar inputs and -4095 to 4095 for bipolar inputs, offering 16-bit resolution and typical voltage/current accuracy of -0.01%/0.06% at 25C, respectively. It also includes open circuit detection, overvoltage protection, and auto-calibration.
Is Your Device Showing These Signs?
The Allen Bradley 1771-IL input module commonly experiences issues such as blown input fuses due to overcurrent events, resulting in a loss of signal detection from field devices. Corrosion on the terminal block and backplane connector pins causes intermittent or complete communication failures with the PLC chassis. Degradation of internal components, specifically electrolytic capacitors, leads to erratic input signal readings and module malfunction. Troubleshooting involves checking input voltages, inspecting wiring for shorts, and verifying proper backplane connectivity to ensure reliable operation within the Allen Bradley PLC system.
