Product Description:

The E0241-653-064-1 CRT Board from Okuma is a logic based interface board used in CRT control systems. It integrates essential logic, memory and timing components on a single PCB. The board is designed for dependable signal processing and interaction within display systems. Its build supports consistent operation in demanding control environments.

The E0241-653-064-1 CRT board includes the SN74LS00N quad 2 input NAND gate for basic logic functions and the SN74LS04N hex inverter to reverse logic signals. The SN74LS157N multiplexer enables selection between data lines while the SN74LS374N octal D-type flip flop stores temporary data for synchronization. Additional logic ICs include the SN74LS32N quad 2 input OR gate and the SN74LS86N quad 2 input XOR gate. The board features a NEC D2732D EPROM that provide 32 kilobits of UV erasable non volatile memory for firmware storage. This chip supports custom code storage essential for board functionality. A CINCON CMO-1600A crystal oscillator generates a 16.000 MHz clock signal which acts as the system’s timing reference. The oscillator offers accurate clock timing needed for synchronous logic function. These components combine to deliver reliable data handling, selection and output generation across the system. The design of the board supports simple integration into larger systems.

The E0241-653-064-1 CRT board uses multiple 0.1μF ceramic capacitors for noise reduction and logic IC decoupling. Electrolytic capacitors help stabilize power input while toroidal inductors manage electromagnetic interference and maintain circuit integrity. The model includes practical connectivity options. A primary edge connector on the top allows seamless connection to a motherboard or backplane. Two blue multi pin connectors located on the bottom serve for I/O or power interfacing. The E0241 series board combines reliable logic sequencing, timing and memory into a single module.
