Configure through RSLogix software with pre-built function blocks that accelerate commissioning timelines and reduce programming complexity.

Common Technical Questions

Q: What's the difference between the /C and standard 1734-OE2C versions?
A: The /C suffix indicates conformal coating applied to the circuit board, providing enhanced protection against moisture, dust, and chemical exposure in demanding industrial environments.

Q: Can I use this module for 0-10V output applications?
A: No, the 1734-OE2C/C is specifically designed for current output (4-20mA). For voltage output requirements, consider the 1734-OE2V module from the same POINT I/O family.

Q: How do I calibrate the output channels?
A: The module features factory calibration with stored coefficients. Field calibration is typically unnecessary, but if required, use the calibration utilities within RSLogix software following the procedure outlined in publication 1734-UM011.

Q: What wire gauge should I use for field connections?
A: The removable terminal blocks accept 14-22 AWG (0.25-2.5 mm²) copper wire. Use shielded twisted-pair cable for analog signals to minimize electromagnetic interference in noisy industrial environments.
