1794-IB16 是一款 Flex IO 分立式输入模块

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, which is primarily used to implement distributed IO solutions. In distributed I/O architectures, I/O modules can be installed near the signal source or driver load. This greatly reduces the laying of cables, 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 base to which the signal cable is terminated. Compatible terminal bases are 1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, and 1794-TB37DS. In addition, the 1794-IB16 requires the use of a communication adapter to transfer I/O data to a partner scanner module or controller. Compatible communication adapters include 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, and Profibus with directory number 1794-APB Communication adapter and ControlNet communication adapter with directory number 1794-ACN.

The current consumption of 1794-IB16 is 30 mA @ 5V DC. The rated voltage of each input channel is from 10 to 31.2 VDC, and the nominal input voltage is 24VDC. The minimum on-state voltage for each channel is 10VDC, the maximum is 31.2VDC, and the maximum off state voltage is 20VDAC. It has a power consumption of 3.5W@31.2V DC and a thermal dissipation of 11.9BTU/hr@31.2V DC.

The 1794-IB16 module has 16 suction current inputs with a nominal on-state voltage of 24V DC, a range of 10-31.2V DC on-state voltage, and a minimum off state current of 1.5mA. It has a maximum power consumption of 6.1W at 31.2V DC. The terminal base units compatible with this module are 1794-TB3, 1794-TB3S, 1794-TB3K, 1794-TB3SK, 1794-TBKD, and 1794-TB37DS.

The module supports DIN rail or panel mounting and supports various communication adapters such as ControlNet, DeviceNet, EtherNet/IP, and Universal Remote I/O. The 1794-IB16 module has 16 yellow leds as status indicators for each channel. The LED indicates the corresponding input device and output signal. It also has D and XT versions of standard modules for diagnostics and extreme environments, reducing panel and maintenance costs. It operates at A temperature of 0-55 °C (32-131 A °F) and a relative humidity of 5-95% non-condensing.
