Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.

Product Overview

The Allen-Bradley 1756-IF6I is a ControlLogix isolated analog input module supporting six individually isolated current or voltage inputs. It resides in a single ControlLogix chassis slot and acquires analog signals configurable as ±10 V, 0-10.5 V, 0-5.25 V or 0-21 mA. Typically deployed in industrial control systems for tasks such as process monitoring, sensor data acquisition, or machine condition input in manufacturing or infrastructure applications.

Best Suited For

  • Distributed analog input on ControlLogix backplane
  • Voltage and current signal acquisition (configurable per channel)
  • Process monitoring in manufacturing systems
  • Isolated input applications requiring channel-to-channel and channel-to-backplane isolation
