If you’re looking to install or troubleshoot the 1734 OE4C module, you’ve come to the right place. This guide will provide you with a detailed wiring diagram, as well as frequently asked questions and troubleshooting tips to ensure your installation runs smoothly.
What is the 1734 OE4C?
The 1734 OE4C is an analog output module designed for use with Allen-Bradley’s CompactLogix and MicroLogix programmable logic controllers (PLCs). It provides four channels of 0-10V DC, -10 to +10V DC or 4-20mA current, with 12-bit resolution. Each channel is individually configurable for voltage or current output, and each can be programmed with a scaling factor to convert the input signal into the desired output range.

The following wiring diagram illustrates the connections required for a typical installation of the 1734 OE4C module:
| Terminal Number | Description | Wire Color |
|---|---|---|
| 1 | Analog Output Channel 1 (+) | Red |
| 2 | Analog Output Channel 1 (-) | Black |
| 3 | Analog Output Channel 2 (+) | White |
| 4 | Analog Output Channel 2 (-) | Blue |
| 5 | Analog Output Channel 3 (+) | Yellow |
| 6 | Analog Output Channel 3 (-) | Green |
| 7 | Analog Output Channel 4 (+) | Brown |
| 8 | Analog Output Channel 4 (-) | Orange |
| 9 | +24V DC | White/Orange Stripe |
| 10 | 0V DC (Common) | White/Brown Stripe |
Power Supply Connections
Terminals 9 and 10 are used to connect the 1734 OE4C module to the power supply. Terminal 9 is connected to the positive 24V DC supply, and terminal 10 is connected to the common or ground of the power supply.
Analog Output Channel Connections
To connect an analog output device to the 1734 OE4C module, you will need to connect the positive (+) wire of the output device to the appropriate terminal (1-4) for the desired output channel, and the negative (-) wire to the corresponding negative terminal (2-8). The color codes listed in the wiring diagram are for reference only and may vary depending on your specific installation.
Configuring Output Channels
Before using the 1734 OE4C module, you will need to configure each output channel using Allen-Bradley’s RSLogix software. This involves setting the output range (e.g. 0-10V DC, 4-20mA), as well as the scaling factor to convert the input signal into the desired output range.
Frequently Asked Questions
1. Can I use the 1734 OE4C module with other PLC brands?
No, the 1734 OE4C module is specifically designed for use with Allen-Bradley’s CompactLogix and MicroLogix PLCs, and may not be compatible with other brands or models.
2. Can I use the 1734 OE4C module for other types of signals besides voltage and current?

3. What is the maximum operating temperature for the 1734 OE4C module?
The 1734 OE4C module is designed to operate in temperatures ranging from -20°C to +60°C (-4°F to +140°F).
4. Can I use the same output range for all four channels?
Yes, each channel can be configured independently, but you also have the option of using the same output range for all four channels if desired.
5. What is the maximum distance between the 1734 OE4C module and the output device?
The maximum recommended distance between the 1734 OE4C module and the output device may vary depending on factors such as the wire gauge and environmental conditions, but is typically around 500 feet.
Troubleshooting Tips
No Output Signal
If you’re not getting any output from the 1734 OE4C module, check the following:
- Ensure that the module is properly powered and that the power supply is delivering the correct voltage.
- Verify that the wiring connections are correct and that the output device is properly connected to the appropriate terminals.
- Double-check the RSLogix configuration settings to ensure that the output range and scaling factors are set correctly.
- If all else fails, try replacing the module with a known working unit to see if the problem resolves.
Inaccurate Output Signal
If the output signal from the 1734 OE4C module is inaccurate or unstable, try the following:
- Check that the input signal to the module is stable and within the specified range.
- Verify that the output device is compatible with the selected output range and scaling factor.
- Inspect the wiring for loose connections or damage.
- Consider using shielded cabling to minimize electromagnetic interference.
- If necessary, adjust the scaling factor or output range in RSLogix to fine-tune the output signal.
