Description：

The 1794-IV32 is part of the Flex I/O platform, typically used in implementing distributed I/O topology. This module is specifically a high-density discrete input module that features Thirty-Two (32) current sourcing input channels. This module is designed to accept nominal input signal voltage of 24 VDC, enabling integration of discrete input signals such as switches, auxiliary contacts, sensors, and similarly binary operating devices. The 1794-IV32 is installed along with a Flex I/O assembly with a Flex I/O communication adapter as the header module. The data within the 1794-IV32’s local memory is transferred via the FlexI/O bus which is then forwarded to the host controller through a communication highway. The 1794-IV32 has a FlexBus current draw of 40 mA at 5 VDC. It has a minimum On-state voltage of 19.2 VDC while the maximum On-state voltage is 31.2 VDC. Additionally, the minimum On-state current is 2.0 mA while the maximum is 6.0 mA. Configurable filter times are available to this module specifically, 0.25 ms; 0.5 ms; 1 ms; 2 ms; 4 ms; 8 ms; 16 ms, and 32 ms. Filter times can be used to eliminate false activation due to debouncing or noises. The default filter time is 0.25 ms.
