The 1794-IV16 is a Sixteen (16) channel 24VDC Discrete sourcing input module. This module belongs to the 1794 Flex IO product catalog that is used to implement distributed IO solution. This module supports DIN rail mounting and compatible for use with any Flex IO communication adapter.
The 1794-IV16 requires a compatible terminal base to operate. This module is most compatible with terminal base 1794-TB2 however, it may also be used with 1794-TB3, 1794-TB3S, 1794-TBKD. The terminal base provides the DIN rail attachment, module keyswitch and terminals intended for I/O and Power wiring.
This modules circuitry is energized by power present in the backplane rated 30 mA @ 5V DC. The input channels are capable of receiving a voltage range of 10 to 31.2 VDC with nominal input voltage of 24VDC. It has a minimum On-state voltage of 10VDC and maximum of 31.2VDC.
The module has an adjustable input filtering to allow tuning of input signals. Input filtering may help to prevent false positive and negative detection thus, improving accuracy of the system. Input filtering may be modified through the programming software or via a user program that modifies the input filtering registers. Valid OFF to ON and ON to OFF input filter time are 0.25ms, 0.5ms, 1ms, 2ms, 4ms, 8ms, 16ms, 32ms. The module is set by default at 0.25ms filter time. This may be modified in the software by manipulating WORD 3 of the 1794-IV16 register.
This module measures 94H x 94W x 69D mm and weighs 7 pound-inches. It has Sixteen (16) Yellow indicators to provide feedback status of instruments.
VIIIVThe 1794-IV16 is a Flex IO Sixteen (16) channel 24VDC sourcing input module. This module can be fitted with any 1794 Flex IO adapters to implement distributed I/O application.
