Toshiba EN751A (GEN751AS) Ethernet Network Communication Module – Prosec T Series PLC
When a critical Ethernet communication link fails on the factory floor, the consequences cascade instantly — production lines halt, SCADA systems lose visibility, and maintenance teams scramble under pressure. The Toshiba EN751A (part number GEN751AS) is the network communication backbone of the Prosec T Series PLC platform, and without it, the entire distributed control architecture loses its ability to exchange real-time data across the plant network. Downtime is not just inconvenient — it is costly.
The EN751A occupies a specialized position within the Toshiba Prosec T Series ecosystem as a dedicated Ethernet network interface module. Designed for high-reliability industrial environments, this module enables seamless integration between Prosec T Series PLCs and plant-wide Ethernet networks, supporting peer-to-peer communication, HMI connectivity, and upper-level SCADA or MES systems. Its global installed base spans automotive, chemical, power generation, and process manufacturing industries, making it one of the most recognized Toshiba PLC communication components in the international industrial automation market.

Frequently Asked Questions
- Q: Is the EN751A the same as GEN751AS?
- A: Yes. EN751A is the module model designation, and GEN751AS is the Toshiba part number used in procurement and ordering systems. Both refer to the same physical module.
- Q: Can this module be used with non-Toshiba PLC systems?
- A: No. The EN751A is designed specifically for the Toshiba Prosec T Series backplane and is not compatible with other PLC platforms.
- Q: Do you provide a warranty?
- A: Yes. We offer a standard warranty period on all tested and refurbished units. Terms are specified in the quotation. New-in-box units carry the original manufacturer warranty where applicable.
- Q: What is the lead time?
- A: Lead time depends on current stock availability. In-stock units typically ship within 3–5 business days. Out-of-stock items are sourced within 2–4 weeks. Contact us for real-time availability.
- Q: Can you provide a datasheet or technical manual?
- A: We can assist in locating Toshiba technical documentation for the Prosec T Series. Contact our team with your specific request.
