Product Description
The Allen-Bradley 1747-L40F is a compact yet powerful fixed controller within the SLC 500 system, featuring 1024 words of user memory, a built-in power supply, and fixed I/O (12 DC sink inputs, 8 DC transistor source outputs, and a high-speed counter). Operating on 24V DC, it boasts a 4 microsecond bit execution time and a typical scan time of 8 milliseconds per 1K, with heat dissipation between 7.4 and 15 Watts. It utilizes capacitor-based RAM with EEPROM backup and supports Belden 9463 cable for wiring. Programming and troubleshooting are facilitated via a Hand-Held Terminal (HHT), while communication is handled through an RS-232 port. Designed for industrial environments (0-60C, 2.5G vibration tolerance), the 1747-L40F offers NEMA standard noise immunity and enclosure protection, along with LED indicators for key statuses. Its versatility is further enhanced by a 2-slot expansion chassis for additional I/O modules and optional modules for ControlNet, DeviceNet, Universal Remote I/O, BASIC programming, DH-485, and additional RS-232 communication. The SLC 500 series, known for its reliability and customer satisfaction, is suitable for applications like HVAC control, small process control, and assembly operations.
