The 1734-IE4C (1734IE4C) is a high-density 4-channel analog input module from the Allen-Bradley POINT I/O family. Designed for space-constrained applications, this module provides four independent channels for measuring industrial current signals, typically in the 0 to 20 mA or 4 to 20 mA range. As part of the modular POINT I/O system, the 1734-IE4C offers a compact footprint (12.7 mm width) without compromising on performance, featuring a 16-bit resolution for high-precision data acquisition. It is an ideal solution for monitoring process sensors such as flow meters, pressure transmitters, and temperature transducers in Distributed I/O configurations.
The 1734-IE4C utilizes a Sigma-Delta conversion technique to deliver high-accuracy digitized values to the controller via the POINT I/O backplane (PointBus). Each channel is individually configurable, allowing for tailored filter frequencies and scaling. A key engineering advantage of the module is its on-board diagnostics, which can detect open-circuit (wire break) conditions in 4–20 mA mode and signal range over/under-flow errors. The module is "hot-swappable," allowing for Replacement Under Power (RIUP) when used with the appropriate terminal base, significantly reducing downtime during maintenance cycles.
| Attribute | Specification Details |
| Model | 1734-IE4C |
| Brand | Allen-Bradley (Rockwell Automation) |
| Series | POINT I/O |
| Number of Inputs | 4 Single-Ended |
| Input Signal Range | 0 to 20 mA / 4 to 20 mA |
| Resolution | 16-bit (0.305 µA/cnt) |
| Input Impedance | 50 Ω |
| Conversion Type | Sigma-Delta |
| Step Response | 70 ms to 430 ms (depending on filter) |
| POINTBus Current | 75 mA @ 5V DC |
| Isolation Voltage | 50 V (continuous), Basic Insulation Type |
| Terminal Base Unit | 1734-TB or 1734-TBS |
How does the 16-bit resolution affect measurement precision?
With 16-bit resolution, the 1734-IE4C can divide the 0–20 mA range into 65,536 discrete steps. This results in a precision of approximately 0.305 µA per count, allowing the control system to detect minute changes in sensor feedback, which is critical for high-accuracy chemical dosing or precision pressure control.
Is the 1734-IE4C compatible with all POINT I/O adapters?
Yes, it is designed for universal compatibility with 1734-series communication adapters, including 1734-AENT (EtherNet/IP), 1734-ADN (DeviceNet), and 1734-APB (PROFIBUS). Ensure your controller's EDS (Electronic Data Sheet) files are updated to the latest version for seamless integration.
Does this module provide power to the sensors?
The 1734-IE4C receives its power from the POINT I/O backplane and the field power bus. While it can measure current from loop-powered sensors, the 24 VDC excitation power for the sensors is typically distributed through the 1734-FPD (Field Power Distributor) or the common power terminals on the 1734-TB base.
