The Allen-Bradley 1734-IE2C delivers precise current measurement for demanding industrial environments. This module features two single-ended, non-isolated input channels. It converts analog current signals into reliable digital data for your control system.
This module provides a resolution of 16 bits over a 0 to 21 mA range. This equates to a granularity of 0.32 μA/cnt, enabling fine-grained process monitoring. You can configure each channel for either 0-20 mA or 4-20 mA operation. The module offers an absolute accuracy of 0.1% Full Scale at 25 °C.
The 1734-IE2C uses a Delta-Sigma conversion method for stable readings. Factory calibration ensures consistent performance right out of the box. The system stores converted data in a Signed Integer format. This design minimizes signal noise and drift for critical applications.
You must mount this module onto a compatible terminal base unit. Acceptable bases include the 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS. Align the module’s keyswitch to position 3 during installation. This mechanical keying prevents incorrect module placement in the system.
Wiring the module requires 22 to 14 AWG shielded copper wire. The insulation must be rated for at least 167 degrees Fahrenheit. This module supports both horizontal and vertical mounting orientations. You can attach it securely to a standard 35 mm DIN rail.
The input step response varies based on your chosen notch filter setting. At the default 60 Hz notch, each channel responds in 70 ms. For faster 500 Hz filtering, the response time drops to just 8 ms. The total module update rate is 100 ms at the 60 Hz default setting.
The module draws 75 mA from the 5V DC backplane supply. It dissipates a maximum of 0.6 W of power at 28.8V DC. This low power consumption helps manage heat inside the control cabinet. The module is an open-style device for use within a rated enclosure.
The 1734-IE2C requires an external 24V DC nominal power supply. The input voltage range is 10 to 28.8 Volts DC. This module provides continuous isolation of 50 Volts DC. It also withstands a dielectric test of 2550 Volts DC for 60 seconds.
This input module works with any Allen-Bradley POINT I/O communication adapter. Supported networks include ControlNet, DeviceNet, and EtherNet/IP. This compatibility makes the module a flexible choice for new or existing systems. It integrates seamlessly with any Allen-Bradley controller platform.
