Product Description:
The E0241-653-054B is a digital input interface card designed for Okuma's OSP‑5 CNC control system which resides within the machine's input and output rack that connects via a gold plated edge connector to the backplane. It is designed to capture and process up to 10 discrete input signals, such as limit switches, safety interlocks, tool changer sensors and other industrial automation inputs.
The E0241-653-054B Board has a robust 50 pin D sub external connector which facilitates wiring integration with the machine's field devices that ensures secure and organized routing of signals. It is included with multiple TTL logic chips that includes inverters, quad inverters with Schmitt trigger inputs and latches which collectively condition and buffer incoming signals to enhance noise immunity and maintain signal integrity. It is featured with an array of pull up or pull down resistors aligned with each channel which ensures defined logic levels when signals are inactive and its supporting power stability and transient suppression are electrolytic and ceramic capacitors distributed strategically across the PCB. It has a small DIP switch bank which enables field configuration and allows selection of card address or operational mode. It is made on a quality fiberglass PCB and features clear silkscreen labeling that helps in field identification and servicing.
This E0241 series MSM board LED status indicators provide real‑time visual feedback on each input channel which greatly simplifies system diagnostics and it has a listed weight of approximately 19 kg for shipment including packaging. The module is widely serviced by authorized repair providers and it is a reliable, field proven solution for robust digital input handling in CNC automation.
Frequently Asked Questions about E0241-653-054B:
Q: Why are TTL logic chips used in the E0241-653-054B input card?
A: TTL chips ensure reliable and fast digital signal processing, minimizing data corruption. They help the board respond accurately to input state changes.
Q: How do pull-up or pull-down resistors benefit the E0241-653-054B board’s performance?
A: These resistors ensure stable logic levels when inputs are disconnected. This prevents false triggering due to floating signals.
Q: Why is a DIP switch included on the E0241-653-054B EC Input Card?
A: The DIP switch allows for easy field configuration without needing software. It helps in setting the card address or operation mode directly.
Q: What role do the red status LEDs play on the E0241-653-054B card?
A: They provide real-time input status feedback, aiding diagnostics. Technicians can identify faulty channels or wiring instantly.
Q: Why is a fiberglass PCB used in the E0241-653-054B board construction?
A: Fiberglass ensures durability and heat resistance, ideal for industrial environments. It maintains signal reliability under mechanical and thermal stress.
