Allen‑Bradley 1715‑IF16 Redundant Analog Input Module

Product Description

The 1715‑IF16 is a 16‑point analog input module for Rockwell Allen‑Bradley Bulletin 1715 redundant I/O system. It is designed for high‑availability process control applications, supporting simplex and duplex redundant configurations. It receives 4‑20mA analog signals from field transmitters and sends data to the ControlLogix controller via 1715‑AENTR EtherNet/IP adapter. It supports hot‑swap replacement without interrupting the control process, widely used in safety‑critical process industries.

FAQ

Q: What is the difference between simplex and duplex mode for 1715‑IF16?
A: Simplex uses one single module; duplex uses two identical 1715‑IF16 modules for redundant I/O, if one fails the other takes over automatically.

Q: Can it work directly with ControlLogix rack without 1715‑AENTR?
A: No, the 1715 I/O system requires 1715‑AENTR EtherNet/IP adapter to communicate with ControlLogix CPU.

Q: Does this module support 0‑10V voltage input?
A: No, 1715‑IF16 only supports 4‑20mA current signal input.
