| The 24V DC 2 Input Frequency Module performs high-speed frequency algorithms and is capable of reporting frequency, acceleration, and direction. The frequency inputs are capable of accepting frequencies up to 32 kHz. Input devices range from magnetic pickup to flowmeters, to incremental encoders to proximity detectors. The module accepts and returns binary data. Outputs are activated by alarms. Module power is supplied from the external power supply. All power for input devices (24V DC) is supplied by the I/O module. | |||||

| The 24V DC 2 Channel Very High Speed Counter Module has two incremental quadrature encoder interfaces each with three inputs (A, B, and Z). Each input module has ±inputs for connection to pulse transmitters with complementary or non-complementary signals. The counter can count pulses of one or two pulse trains for up/down counting and detection of a selectable number of edges (X1, X2, X4). Each of the two counters has an upper limit of 1MHz, a 24-bit counter register, a preset register, and a latch register. Module power is supplied from an external 24V power supply. The 1794-VHSC has two outputs that can be configured for overlapping, multiple windows, and/or pulse width modulation. Use with 1794-ACN15 or 1794-ACNR15 Series B or later ControlNet adapters or 1794-AENT EtherNet/IP adapter. | |||||
