Product information
Product Overview
The 1756-IF16 is a ControlLogix 16-point analog input module accepting both current and voltage signals: 0…10.25 V, ±10.25 V, 0…5.125 V and 0…20.5 mA ranges, on a 36-pin removable terminal block. Inputs are isolated from the backplane (250 V continuous, reinforced insulation). The module carries a status display showing module health, calibration and mode, and draws 3.53 W at full load. It is the workhorse analog input card for 4–20 mA transmitters in ControlLogix panels.

Lifecycle Status & Availability
Rockwell lists the 1756-IF16 as Active (Series B). Note the catalog also carries the 1756-IF16K conformally coated variant and the 1756-IF16H HART-capable version for smart transmitters — confirm which variant matches your panel before ordering.
Typical Applications
- 4–20 mA transmitter duty: pressure, level, temperature and flow loops in ControlLogix panels
- Mixed voltage/current analog panels standardizing on one 16-point input card
- Spares pools for process skids and machine builders running 1756 analog I/O
Related & Compatible Models
Family variants: 1756-IF16K (conformal coating), 1756-IF16H/IHK (HART). Higher-resolution alternatives: 1756-IR12/IT16 (RTD/thermocouple), 1756-IF8I (isolated 8-pt). Output counterpart: 1756-OF8. All mount in 1756 chassis with 1756-Px7x power supplies.
Requesting a Quotation
Send the exact catalog number including suffix (IF16 / IF16K / IF16H — different products), the series letter from the label, and quantity. If your transmitters need HART passthrough, say so — the plain IF16 does not provide it. Pricing and availability are confirmed by quotation.
Frequently Asked Questions
Does the 1756-IF16 support HART?
No — the plain IF16 reads the analog signal only. HART-capable duty requires the 1756-IF16H variant. Confirm your transmitter type before ordering.
What is the difference between IF16 and IF16K?
The K suffix adds conformal coating for corrosive environments. The analog function is identical.
Are the channels isolated from each other?
Official data specifies inputs-to-backplane isolation (250 V continuous, reinforced); there is no channel-to-channel isolation on this module. For per-channel isolation requirements, see the isolated analog family.
Which resolution does it offer?
This page quotes the official input ranges. For resolution-critical loops, Rockwell’s high-resolution analog family offers more bits — state your loop requirements in the quotation request and we will confirm the correct catalog number.
