Allen Bradley 1734-IE2C Point I/O 2 Point Analog Input Module

The 1734-IE2C is a 2-channel analog current input module designed for integration within the POINT I/O system architecture. The 1734-IE2C provides conversion of 4...20 mA and 0...20 mA field signals into 16-bit digital representation for process control systems. The unit sends 6 bytes of input data and fault status information across the backplane to the system controller, operating via DeviceNet, PROFIBUS, ControlNet, or EtherNet/IP adapters.

Features

• Provides 2 single-ended, non-isolated current input channels.
• Supports configurable analog input ranges of 4...20 mA and 0...20 mA.
• High-resolution 16-bit analog-to-digital conversion (0.32 uA/cnt) using Delta Sigma conversion.
• Built-in channel status and fault indicators for local diagnostic monitoring.
• Removable Terminal Block (RTB) compatibility allows module replacement without disconnecting field wiring.
• Integrated fault protection up to 28.8V DC.

Applications

• Industrial process automation and monitoring
• 4...20 mA transmitter signal integration
• Factory automation control systems using POINT I/O architectures
• Remote I/O field signal acquisition

Installation Guidelines

• Mounting Base Alignment: Mount the module into a compatible POINT I/O base assembly (1734-TB, 1734-TBS, 1734-TB3, 1734-TB3S, 1734-TOP, 1734-TOPS, 1734-TOP3, or 1734-TOP3S). Set the keyswitch to position 3 prior to installation.
• DIN Rail Grounding: Install onto a zinc-plated chromate-passivated steel DIN rail to ensure proper chassis grounding. Secure the DIN rail every 200 mm (7.8 in.).
• Enclosure Requirements: Mount in an open-style industrial enclosure rated for Pollution Degree 2 environments and compliant with specific application requirements.
• Electrostatic Discharge (ESD): Touch a grounded object or wear an approved grounding wrist strap before handling the electronics.
• Wiring Practices: Use shielded copper wire rated for 75 degC or higher with a maximum insulation thickness of 1.2 mm (3/64 in.).
