Description
Allen-Bradley 1794-IB16 (Rockwell Automation) FLEX I/O digital input module. The1794-IB16 is a widely used Allen-Bradley (Rockwell Automation)FLEX I/O digital input module. Module Type Digital Sinking Input Module. Because this is asinking module, the input channels require asourcing field device. The 1794-IB16 is a widely used Allen-Bradley (Rockwell Automation) FLEX I/O digital input module . It features 16 sinking inputs designed to interface with 24V DC field devices like pushbuttons, limit switches, and proximity sensors in a distributed control network. Technical Specifications Parameter Specification Module Type Digital Sinking Input Module Number of Inputs 16 Channels , non-isolated (share a common return) On-State Voltage Range 10V DC minimum to 31.2V DC maximum Nominal Input Voltage 24V DC On-State Current 2.0 mA minimum @ 10V DC 8.0 mA nominal @ 24V DC Off-State Voltage 5.0V DC maximum Off-State Current 1.5 mA minimum Input Filter Time Off-to-On: 0.25ms, 0.5ms, 1ms, 2ms, 4ms, 8ms, 16ms, 32ms On-to-Off: 0.25ms, 0.5ms, 1ms, 2ms, 4ms, 8ms, 16ms, 32ms (Software configurable; defaults to 1ms) FlexBus Current 30 mA @ 5V DC Power Dissipation 6.1 W maximum @ 31.2V DC Compatible Terminal Bases 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBN, 1794-TB3K, 1794-TB3SK Terminal Base Wiring (Standard 1794-TB3 / TB3S) Because this is a sinking module, the input channels require a sourcing field device. This means the field device switches the positive voltage (+24V DC) into the module terminal, and the module routes it to the common return. Input Mapping (Row A and Row B) Terminals A-0 to A-7: Input Channels 0 through 7 Terminals B-8 to B-15: Input Channels 8 through 15 24V DC Power & Common Routing (Row C) Terminals C-34 to C-51: Used to bus the external 24V DC power supply to your field devices and provide the necessary reference common back to the system. Connect +24V DC to terminal C-34 . Connect DC Common (0V) to terminal C-50 . Note on Terminal Bases: If you are using a 1794-TB2 base, Row B is used for the common connections, which alters the pinout configuration significantly compared to the 3-row TB3. Memory Mapping In Studio 5000 / RSLogix 5000, the data from this module is presented in a single 16-bit word. Bit 0: Input Channel 0 Bit 1: Input Channel 1 ... Bit 15: Input Channel 15 Additionally, configuration words allow you to change the input filter times for channels 0–11 and 12–15 to prevent contact bounce or electrical noise from triggering false inputs.
