About 1769-HSC

The Allen-Bradley 1769-HSC is a compact high-speed counter with its own microprocessor that reacts to high-speed input signals. The module can produce rate and time interval data and it has four channels of pulse/counts inputs. Thus, it has 6 differential DC inputs, 4 sourcing DC outputs, and 12 virtual outputs. The input array of the module has accumulated pulse counts. This makes the onboard outputs react to input conditions at high-speed. The 1769-HSC features a 1 Mhz counter/encoder input with 4 on-board sourcing outputs of 5 to 30 Volts DC. It is necessary for high-speed control applications that include flow control, measuring length, position, speed, frequency, or duration. The 1769-HSC module has 425 mA at a 5 Volt DC bus current draw and 0 mA at a 24 Volt DC bus current draw. It has a heat dissipation peak 6.21 Watts and an isolation voltage of 75 Volts reinforce insulation test to withstand 1200 Volts AC for 2 seconds.

The 1769-HSC has a 90 degree Celsius or 194 degrees Fahrenheit wire type and its wire can reach up to 22 to 14 AWG solid copper wire or 22 to 16 AWG stranded copper wire rated at 90 degrees Celsius (194 degrees Fahrenheit) insulation. The cable should be an individually-shielded or twisted-pair cable. The module's wiring category is 2 on signal ports and the enclosure type rating is open-style. The 1769-HSC module has 2 quadrature differential inputs and input voltage that ranges 2.6 to 30 Volts DC. It has a minimal ON-state current 6.8 mA and OFF-state voltage max is 1.0 Volt DC. Its OFF-state current and leakage current is 1.5 mA. The module's input current max is 15 mA and 6.8 mA minimal input current. The module has a 1950 Ohm input impedance and a pulse width of 259 ns. It comes with a minimal phase separation of 131 ns. It has voltage output range 5 to 30 Volts DC and user power -0.1 Volts DC On-state max voltage. Its reverse polarity protection is at 30V DC. The 1769-HSC’s turn-on time max is 400 μs and minimal 200 μs turn off time. Its operating temperature is 0 to 60 degrees Celsius and non-operating -40 to 85 degrees Celsius; the maximum surrounding air temperature is 40 degrees Celsius.
