Allen-Bradley 1734-IE2C 2-Point Analog Current Input Module
The Allen-Bradley 1734-IE2C is a high-precision POINT I/O analog current input module engineered for demanding industrial process control applications. This compact module delivers exceptional 16-bit resolution across two independent current input channels, ensuring accurate signal acquisition in manufacturing, chemical processing, and automated production environments.
Technical Specifications
- Input Channels: 2 differential analog current inputs
- Input Range: 4-20mA, 0-20mA selectable per channel
- Resolution: 16-bit (65,536 counts) for superior accuracy
- Update Rate: 10ms typical per channel
- Accuracy: ±0.1% of full scale at 25°C
- Isolation: Channel-to-backplane isolation 50V continuous
- Operating Temperature: 0 to 60°C (32 to 140°F)
- Power Consumption: 1.5W maximum from backplane
- Mounting: DIN rail via POINT I/O terminal base
- Compatibility: Works with 1734-AENT, 1734-AENTR adapters
Key Applications
This module excels in process monitoring scenarios requiring precise current loop measurements:
- Temperature transmitter interfacing (4-20mA sensors)
- Pressure and flow measurement systems
- Level detection in tanks and vessels
- Chemical dosing and batching operations
- HVAC system monitoring and control
- Water treatment plant automation
Engineering Solutions
The 1734-IE2C addresses common industrial challenges through intelligent design. Its differential input architecture rejects common-mode noise, critical in electrically noisy factory floors. The module's hot-swappable capability minimizes downtime during maintenance, while built-in diagnostics provide real-time channel health monitoring through your ControlLogix or CompactLogix controller.
Configuration is streamlined through RSLogix 5000/Studio 5000 software, with pre-built Add-On Instructions (AOIs) available for rapid integration. The module automatically scales raw counts to engineering units, reducing programming complexity and commissioning time.
Frequently Asked Questions
Q: Can I mix 4-20mA and 0-20mA inputs on the same module?
A: Yes, each channel is independently configurable for either 4-20mA or 0-20mA operation through software configuration.
Q: What terminal base is required for installation?
A: The module requires a 1734-TB, 1734-TBS, or 1734-TOP terminal base. We recommend the 1734-TOP terminal base for most applications.
Q: Does this module support HART communication?
A: No, the 1734-IE2C is a standard current input module. For HART-enabled inputs, consider the 1734-IH module series.
Q: What's the maximum cable length for 4-20mA signals?
A: With proper shielded cable, you can reliably run 4-20mA signals up to 1000 meters (3280 feet) from the transmitter.
Q: Is this module suitable for SIL-rated safety applications?
A: This is a standard I/O module not rated for safety functions. For safety-rated applications, use Allen-Bradley GuardLogix safety I/O modules.
