Technical values are product-identification guidance. Confirm the exact series, revision, markings, documentation and application requirements before ordering or installation.
Platform: Install only in a compatible 1756 ControlLogix chassis. It is not a CompactLogix I/O module.
Terminal block: Confirm whether the quotation includes the required 1756-TBCH or 1756-TBS6H 36-pin removable terminal block.
Series and firmware: Match the offered catalog number, series and firmware to the Studio 5000 project, electronic keying, Add-On Profile and certification requirements. Series A and Series B ratings are not identical.
Alternatives: 1756-IF16, 1756-IF16IH and the conformal-coated 1756-IF16HK are not automatic drop-in replacements. Review wiring, isolation, configuration, firmware, power and approvals before substitution.
It is a 16-channel ControlLogix analog current-input module with an integrated HART interface.
Rockwell specifies 0…20 mA and 4…20 mA current ranges.
No. The module does not provide galvanic isolation between individual input channels.
The module provides integrated HART access. Compatible software, firmware, field wiring and HART devices are still required.
Use a 36-pin 1756-TBCH cage-clamp RTB or 1756-TBS6H spring-clamp RTB, subject to the application requirements.
Rockwell Automation currently lists the catalog number as Active. Recheck lifecycle and the exact series when requesting a quotation.
