2080-IF2 | Allen-Bradley Micro800 2-Ch Current/Voltage Analog Input Module

The 2080-IF2 is a 2-channel analog input module used with the Micro800 and CompactLogix 5380 series PLCs. It allows for the acquisition of analog signals (either voltage or current) from devices such as sensors or transmitters, converting these signals into a form that can be processed by the PLC for control and monitoring purposes. The module supports inputs like 0-10V DC and 4-20mA.

Wiring the 2080-IF2 module involves connecting the analog sensors or input devices to the module’s input terminals. Here’s a basic overview of how to wire the module:

1. Power Connections:

• The 2080-IF2 module is powered by the Micro800 or CompactLogix 5380 backplane. Ensure that the PLC is powered properly before proceeding.

2. Analog Inputs:

• For Voltage Inputs (0-10V DC):
  Connect the positive lead of the voltage signal to the V+ terminal of the module.
  Connect the negative lead to the V- terminal (common).
• For Current Inputs (4-20mA):
  Connect the positive lead of the current signal to the I+ terminal.
  Connect the negative lead to the I- terminal (common).

3. Grounding: Make sure the system is properly grounded to avoid signal interference.

Always refer to the wiring diagrams in the user manual to ensure proper connections for the input types you are using.

The 2080-IF2 module provides 2 input channels for connecting analog signals. Each channel can independently handle either a voltage (0-10V DC) or current (4-20mA DC) signal.

If the 2080-IF2 module is not reading inputs correctly, follow these troubleshooting steps:

1. Check the wiring: Ensure that the input signal wires are correctly connected to the appropriate input terminals (V+/V- for voltage signals, I+/I- for current signals).
2. Verify input signal range: Ensure that the analog input signal is within the expected range (e.g., 0-10V for voltage or 4-20mA for current). If the signal is outside the expected range, the module may not read it correctly.
3. Check the PLC program configuration: Verify that the module is configured correctly for the type of input being used (voltage or current).
4. Inspect the sensor: If possible, check the sensor or input device to ensure it is functioning correctly and providing the correct output signal.
5. Verify the power supply: Ensure that the PLC and the module are powered correctly.

The 2080-IF2 module has a 12-bit resolution. This means that the analog input values are divided into 4,096 discrete levels (2^12), allowing for precise measurement and control of the analog signal within the specified input range.
