The 1734-VHSC5 5V High-Speed Counter Module by Allen-Bradley acts as a signal conditioner and a counter between the POINT BUS back-plane by carrying command information and the customer process signals. The 1734-VHSC5 5V High-Speed Counter Module receives feedback from the encoder, the pulse generator, and the mechanical limit switch. It has a filter for setting 4 selectable (50 Hz, 500 Hz, 5 kHz, and 50 kHz) frequencies, which can also be switched off to achieve the fastest possible counting rate. The 1734-VHSC5 has a single counter, with 4 windows to compare from 1 out of the 2 groups of outputs. Its input voltage is 5V DC, and its input current is 19.1mA at 5V DC and 25.7mA at 6V DC. This VHSC Module is in Key Switch Position 2.

The 1734-VHSC5 has an input filter selection with an OFF-switch and 4 other selectable options (10μs at (50 kHz), 100μ at (5 kHz), 1ms at (500 Hz), and 10ms at (50 Hz)) to choose from, with maximum frequency set at 1MHz counter and encoder X1, 500kHz encoder X2, and 250 kHz encoder X4 configuration (no filter). The 1734-VHSC5 has an On to OFF/OFF to ON delay time at 25µs (load dependent)/150µs (load dependent). Its output supply voltage ranges between 10 and 28.8V DC, with a drop voltage of <0.3V DC at 0.5A. it has <0.5mA current leakage, at a maximum ON STATE current of 0.5A. Its output is protected from short-circuiting at 6A, and during this, the output can either cycle till the fault is rectified of it will just latch off. The 1734-VHSC5’s operational temperature range is -20-55°C (-4-131°F), at a 5-95% non-condensing relative humidity range with dimensions of 2.21in x 0.47in x 2.97in and an approximate weight of 1.15oz.
