The Allen-Bradley 1794-IB16 is a sixteen (16) channel 24VDC discrete input module. The module is part of the 1794 Flex IO product family and is primarily used to implement distributed IO solutions. With a distributed I/O architecture, I/O modules can be installed near the signal source or driver load. This greatly reduces the running of the cable, thus reducing the overall installation cost. It also simplifies maintenance and helps to increase the uptime of the control system overall.

The 1794-IB16 supports standard DIN rail mounting or direct panel mounting. The module is used with the terminal block to terminate the signal wiring on the terminal block. Compatible terminal blocks are 1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, 1794-TB37DS. In addition, the 1794-ib16 requires the use of a communication adapter to transfer I/O data to a partner scanning module or controller. Compatible communication adapters are DeviceNet communication adapter with directory number 1794-ADN, remote I/O communication adapter with directory number 1794-ASB, Ethernet communication adapter with directory number 1794-aent, Profibus communication adapter with directory number 1794-APB and directory number 1794- ControlNet communication adapter for ACN.

The current of 1794-IB16 is plotted as 30 mA @ 5V DC. Individual input channels are rated from 10 to 31.2 VDC, nominal input voltage is 24VDC, and sink cabling configuration is supported. The minimum on-state voltage of each channel is 10VDC, the maximum on-state voltage is 31.2VDC, and the maximum off-state voltage is 20VDAC. Power consumption is 3.5W at 31.2V DC and heat dissipation is 11.9BTU /hr at 31.2V DC.

The 1794-IB16 module has 16 current absorbing inputs rated in the On-State voltage range of 24V DC, 10-31.2V DC On-State voltage range, and a minimum Off-State current of 1.5mA. At 31.2V DC, the maximum power consumption is 6.1W. The terminal bases compatible with this module are :1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, 1794-TB37DS.
