About 1794-VHSC
The 1794-VHSC Module is a high-speed counter module manufactured by Allen-Bradley/Rockwell Automation as a Flex I/O 1794 series counter module. This intelligent input and output counter module is intended to provide high-speed counting for different industrial applications and it provides signals to various compatible programmable controllers that support the EtherNet communication protocol. This module comes with 2 input channels, and 2 counters per input channel, and it is configured for 3 different encoder modes with terminations rated at 5 Volts DC or at 15 to 24 Volts DC. The 1794-VHSC High-Speed Counter Module comes with 19.1 milliamps of rated input current at 5 Volts DC and 25.7 milliamps of rated current at 6 Volts DC with a termination of 5 Volts DC. This high-speed counter module's input current at 15 Volts DC is 6.1 milliamps, and this current is 10.2 milliamps at 24 Volts DC.
The Allen-Bradley 1794-VHSC High-Speed Counter Module features a counter which depends on the on-state and off-state input ratings, and that operates with an input frequency of up to 1 MHz. It also has 4 isolated outputs that are arranged in 2 groups with 0.5 Amps of electrical current rating at 5 Volts DC and 1.0 Amp of electrical current at 12 to 24 Volts DC. The Allen-Bradley 1794-VHSC High-Speed Counter Module features 10 to 31 Volts DC and 5 to 7 Volts DC of output supply voltage, with an off-state leakage current of less than 300 uA. It also has a voltage loss rating of 0.9 Volts DC at a current of 0.5 Amps with a termination of 5 Volts DC and a loss of 0.9 Volts DC at a current rating of 1 Amp with a termination of 12 to 24 Volts DC. This unit operates at a temperature ranging from 0 to 55 degrees Celsius at 5 to 95 percent relative humidity.
The Allen-Bradley 1794-VHSC High-Speed Counter Module features 2 input channels. It has 5 Volts DC of rated input voltage and operates with an on-state current of 5 milliamps.
