Product Overview
The Allen-Bradley 1756-IF8HK is a conformal-coated HART analog input module for the ControlLogix platform. It provides 8 differential current/voltage input channels with integrated HART communication, enabling process variable measurement and smart device diagnostics in harsh industrial environments.
Key Specs
- Input channels: 8 differential, current/voltage
- Input ranges: 0-20 mA, 4-20 mA, 0-5 V, 0-10 V, ±10 V
- Resolution: 16 bits (15 bits + sign bipolar)
- HART support: HART 5, 6, 7 protocol versions
- Current draw: 150 mA @ 5.1 V DC, 40 mA @ 24 V DC
- Isolation: 250 V continuous, channel-to-backplane
- Conformal coating: Yes, for corrosive environments
Why Choose This
- Conformal coating protects against moisture, dust, and corrosive atmospheres
- Simultaneous analog and HART digital data from each channel
- Open wire detection and broken wire diagnostics on 4-20 mA loops
- Removal and insertion under power (RIUP) for maintenance without shutdown
Common Questions
- What is the K suffix? The K suffix indicates conformal coating for use in harsh or corrosive environments.
- How many HART devices can it communicate with? All 8 channels support simultaneous HART communication at 1200 baud.
- Which software configures this module? Studio 5000 Logix Designer with the appropriate Add-on Profile.
Mounting Steps
- Power down the ControlLogix chassis before installation.
- Insert the module into any available 1756 slot and press firmly until seated.
- Attach the 1756-TBCH or 1756-TBS6H removable terminal block.
- Wire field devices using shielded twisted-pair cable, grounding shields at one end.
- Configure the module in Studio 5000 Logix Designer and verify channel status LEDs.
Buying Advice
- Select the 1756-IF8HK over the standard 1756-IF8H for installations in corrosive or high-humidity areas.
- For isolated channels, consider the 1756-IF8IH instead.
- Verify the chassis power supply budget: 150 mA at 5.1 V DC per module.
