Product Description:
The E4809-045-045-E ECP Board is a control and interface module for modular systems that necessitate reliable signal handling and processing. The board provides support for a variety of logic and communication functions that are essential for industrial automation. It is designed to function in conjunction with other control units or backplanes and contains digital logic components.
In the E4809-045-045-E board, several TTL logic ICs, including the 74LS245, 74LS244, and 74LS373, are responsible for signal routing and data buffering. The ECP board's reprogrammable MCM 27128 EPROM chips are socket-mounted and feature a 128 KB UV-erasable memory. The primary controller is a larger integrated circuit (IC) located in the upper left corner, such as an Intel microcontroller. A number of PALs or GALs are responsible for the board's distinctive decoding and timing functions. The blue DB-9 or DB-25 connectors, which are situated on the right side, can be used to attach it to RS-232 or RS-485 serial or parallel devices. In accordance with IEC 60068-2-6, the board's vibration resistance is specified at 0.75 g and 5-500 Hz. The shock resistance satisfies the standards of IEC 60068-2-27 with a peak acceleration of 15 g and a duration of 11 ms.
The E4809-045-045-E ECP board is suitable for use in environments with non-condensing humidity levels ranging from 10% to 90% RH, and it can withstand storage humidity levels ranging from 5% to 95% RH. The recommended temperature range for storage is -40°C to 85°C. This module is designed to be easily upgraded or replaced in the field thanks to its various socketed components. The E4809-045-045-E is designed for settings that require dependable signal transmission and the ability to configure individual components.
