The 1746-ITV16 is a 16-point digital DC sinking input module designed for the SLC 500 platform. It fits into any available slot in a 1746 I/O chassis except slot 0 and provides 16 inputs per module with 16 inputs per common to interface with various field-side DC devices.
16-Point High Density/span>
Fast Response DC Sinking
Integrated Optical Isolation
This module operates within a voltage range of 10 to 30V DC and features a maximum off-state leakage current of 1.5 mA. It utilizes optical isolation to protect the system backplane from field-side electrical noise and has a maximum signal delay of 8.0 ms for both ON and OFF states to ensure reliable digital signal processing.

Power Generation
Monitors discrete status signals from circuit breakers and auxiliary switchgear in electrical substations. The module utilizes optical isolation to protect the system backplane from high-voltage field-side electrical noise.
Oil and Gas
Interfaces with proximity sensors and limit switches on drilling rigs and pipeline monitoring stations. It supports a wide DC sinking input range of 10V to 30V to accommodate various field instrumentation requirements.
Water Treatment
Tracks digital feedback from pump motor starters and float level switches in municipal distribution facilities. The 16-point high-density design allows for centralized monitoring of multiple discrete field devices within a single chassis slot.
Automotive Manufacturing
Processes inputs from presence sensors and safety interlocks on automated assembly lines and conveyor systems. It provides a consistent 8.0 ms signal delay to ensure reliable digital signal processing for high-speed discrete operations.
Steel and Mining
Regulates material handling equipment and furnace door status indicators in smelting plants and underground mines. The robust DC input circuitry is designed to operate reliably in harsh industrial environments with significant electromagnetic interference.
Food and Beverage
Coordinates input signals from bottling machinery, packaging lines, and automated sorting systems. This ensures accurate detection of product placement and machine synchronization through filtered digital DC sinking inputs.
During installation or wiring, personnel must strictly follow Electrostatic Discharge (ESD) precautions by wearing a grounding wrist strap to avoid damaging internal circuit board components and must verify that all chassis power is removed before inserting or removing the module to prevent injury or equipment damage. To ensure accurate signal detection, the module specifies a maximum off-state voltage of 5.0V DC and a nominal input current of 8 mA at 24V DC, while the 16 input points share a single common connection that must be wired according to the sinking configuration.
Proper cable management and the use of the 1746-RT25 removable terminal block are recommended to maintain secure field-side connections while protecting the optical isolation interface from external electrical interference.
What is the operating voltage range and input type for the 1746-ITV16 module?
The 1746-ITV16 is a 16-point DC sinking input module that operates within a voltage range of 10V to 30V DC at 30°C and 10V to 26.4V DC at 60°C.
What are the backplane current requirements for the 1746-ITV16 at 5V and 24V DC?
The module has a backplane current draw of 85 mA at 5V DC and 0 mA at 24V DC, which must be considered during chassis power supply loading.
What are the off-state voltage and current specifications for the 1746-ITV16?
The maximum off-state voltage is 5.0V DC and the maximum off-state leakage current is 1.5 mA, ensuring the module does not falsely trigger from leakage.
