Configured for precise analog current data acquisition in EtherNet/IP and DeviceNet network configurations, the Allen-Bradley 1734-IE2I (1734-IE2I Analog Input Module) provides direct physical/electrical execution.
The Allen-Bradley 1734-IE2I integrates 2 high-resolution 16-bit analog current input channels featuring channel-to-channel galvanic isolation to mitigate ground loop interference in complex sensor loops. Designed for seamless insertion into the POINT I/O backplane architecture, the module delivers fast conversion speed and high noise immunity across deterministic networks like EtherNet/IP. Its compact slice footprint maximizes DIN-rail I/O density scaling while maintaining channel status diagnostics via LED indicators on the module front panel.
Frequently Asked Questions
Q: Can the 1734-IE2I module be hot-swapped while the POINT I/O backplane is powered?
A: Yes. The 1734-IE2I supports Removal and Insertion Under Power (RIUP) when mounted on a 1734-TB or 1734-TBS terminal base assembly, allowing module replacement without disturbing adjacent I/O modules or backplane communications.
Q: How does channel-to-channel isolation benefit 4-20 mA current loops on the 1734-IE2I?
A: Individual channel isolation prevents potential differences between field sensor grounds from inducing measurement errors or damaging module circuitry, maintaining high signal integrity across diverse field instrumentation.
Q: What power supply voltage is required to operate the 1734-IE2I input circuitry?
A: The module operates on 24 VDC nominal field power provided via the POINT I/O power bus or an external power supply module (1734-FPD).
Field Installation Guidelines
Snap the compatible 1734 terminal base assembly (1734-TB or 1734-TBS) securely onto the 35 mm DIN rail.
Align the module key switch to position 1 for current input configuration prior to inserting the 1734-IE2I module into the base.
Terminate 4-20 mA field loop wiring into the designated screw or spring terminals, adhering to proper shielding practices.
Ground cable shields at a single point near the enclosure entry to prevent ground loops across field channels.
Push the module firmly into the terminal base until the latching mechanism locks into place.
