Allen-Bradley 1734-IE2V – 2-Point Analog Voltage Input Module | POINT I/O Platform
Engineering Background: The 1734-IE2V is part of Rockwell Automation’s POINT I/O modular I/O system, designed for distributed control architectures where space efficiency and signal accuracy are critical. It integrates seamlessly into ControlLogix, CompactLogix, and SoftLogix control systems via the POINT I/O adapter backplane.
Product Positioning: Targeted at process control, machine automation, and panel-space-constrained applications, the 1734-IE2V delivers high-resolution analog voltage acquisition in a compact single-slot form factor. It is the preferred choice for procurement engineers specifying distributed I/O in Rockwell-based control architectures.

System Architecture & Signal Flow
The 1734-IE2V mounts directly onto a POINT I/O base unit (1734-TB or 1734-TBS) and communicates via the POINT I/O backplane to the network adapter (e.g., 1734-AENT for EtherNet/IP). Field voltage signals enter through the removable terminal block, pass through the 16-bit ADC, and are transmitted as integer or real-format tags to the Logix controller over the selected network. The module supports both unicast and multicast connections in EtherNet/IP configurations.
Typical wiring: Channel 0 IN+ → Terminal 0 | Channel 0 IN− → Terminal 1 | Channel 1 IN+ → Terminal 2 | Channel 1 IN− → Terminal 3 | Shield/GND → Terminal 4.

Technical FAQ
Q: Is the 1734-IE2V compatible with CompactLogix controllers?
A: Yes. Via a POINT I/O EtherNet/IP adapter (1734-AENT/AENTR), the module integrates with any Logix-based controller including CompactLogix L1–L4x series.
Q: Can I mix 1734-IE2V with current input modules on the same adapter?
A: Yes. POINT I/O supports mixed module types on a single adapter up to the adapter’s power budget.
Q: What is the difference between 1734-IE2V and 1734-IE2C?
A: The 1734-IE2V accepts voltage inputs (±10V, 0–10V, 0–5V, 1–5V); the 1734-IE2C accepts current inputs (0–20 mA, 4–20 mA). Both share the same form factor and backplane interface.
Q: Does the module support HART protocol?
A: No. For HART-enabled analog input, refer to the 1734-IE2CHOE or 1734-IE8C series.
Q: What series letter should I specify?
A: Series B is the current production revision. Please confirm series compatibility with your existing I/O configuration before ordering.
