The 1769-HSC features a 1 Mhz counter/encoder input frequency with Four (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. 

This Allen-Bradley 1769-HSC module is part of the 1769 Compact I/O modules and compatible for use in both the CompactLogix and MicroLogix Programmable Automation Controllers (PAC) and Programmable Logic Controllers (PLC) respectively. It can be used to directly interface with encoders, pulse output of Transmitters and direct connection with fast sensing devices.
