Technical Specifications

Installation Guidelines

• Ensure the power is disconnected from the FLEX I/O base and the module before installation or removal to prevent electrical damage.
• Mount the module onto a compatible FLEX I/O terminal base unit. Ensure the module is firmly seated and locked into position.
• Use appropriate shielded cabling for input signals to minimize electromagnetic interference (EMI) in industrial environments.
• Verify that the field power supply matches the module's voltage requirements (24V DC) before energizing the system.
• Maintain adequate clearance around the module to allow for proper airflow and heat dissipation within the control enclosure.
• Adhere to standard ESD (Electrostatic Discharge) handling procedures when touching the module terminals or internal components.

FAQ

What is the primary function of the 1794-IB16?

The 1794-IB16 is a digital input module used to monitor the status of 16 discrete field devices (such as sensors or switches) and communicate that data to the PLC processor via the FLEX I/O communication adapter.

Does this module require a terminal base?

Yes, the 1794-IB16 is a modular component that must be installed on a compatible FLEX I/O terminal base (such as the 1794-TB2 or 1794-TB3) to provide the necessary wiring connections for field devices.

Is this module compatible with AC voltages?

No, the 1794-IB16 is specifically designed for 24V DC sink-type inputs and should not be used with AC voltage sources.
