The Allen-Bradley 1734-OE4C is a POINT I/O 4-channel analog current output module designed for use with Rockwell Automation's distributed I/O systems. It provides four single-ended, non-isolated analog current output channels configurable for 4-20 mA or 0-20 mA signal ranges. With 16-bit resolution (0.32 µA/cnt) and high-speed DAC conversion (1 µs conversion rate, 160 µs step response to 63%), this module delivers precise analog control signals for industrial process applications. The module requires a 1734-TB or 1734-TBS wiring base assembly and operates on standard 24V DC field power. Applications include valve positioning, variable frequency drive speed control, process variable retransmission, and any application requiring precise 4-20 mA current loop control in distributed automation systems. The module features removable wiring system for easy maintenance, auto device replacement (ADR), and hot-swap capability (RIUP).
**Q: What output signal ranges does the 1734-OE4C support?**
A: The module supports 4-20 mA and 0-20 mA current output ranges, user-configurable via the controller programming software.
**Q: Is channel-to-channel isolation available on the 1734-OE4C?**
A: No, the 4 analog output channels are single-ended and non-isolated from each other and from the field power supply.
**Q: What wiring base is required for the 1734-OE4C?**
A: The module requires a 1734-TB or 1734-TBS wiring base assembly (sold separately).
**Q: Can the 1734-OE4C be hot-swapped?**
A: Yes, the module supports RIUP (Removal and Insertion Under Power), allowing hot-swap replacement without system shutdown.
**Q: What is the maximum resistive load for the current output?**
A: The module can drive up to 750 Ω resistive load on each output channel.
**Q: What is the accuracy of the analog output?**
A: Factory calibrated absolute accuracy is 0.4% at 25°C, which can improve to 0.1% with user calibration.
