WT-PLC-V1 Express

Model: WT-PLC-V1 Express

Category: WT-PLC-V1 Express

The WELLTIMER PLC V1 is a compact and versatile industrial controller designed for automation, monitoring, and communication in oilfield and remote industrial applications. It combines multiple communication interfaces — RS-232, RS-485, Ethernet, and LoRa wireless — enabling seamless integration with Modbus RTU and Modbus TCP devices. Built on a high-performance embedded processor, the WELLTIMER PLC V1 operates reliably in harsh environments and supports both local control logic and remote data acquisition.

Powered by the Welltimer Control Engine, it allows the development of customized automation sequences, real-time data logging, and advanced communication handling. The integrated LoRa module provides long-range wireless connectivity for field devices where traditional wired links are not practical. The PLC’s rugged design, low power consumption, and flexible I/O configuration make it ideal for wellhead automation, remote telemetry, and pump control systems.

In addition, the WELLTIMER PLC V1 supports edge computing capabilities, allowing local data processing and event-based decision-making before transmitting information to cloud or SCADA systems. This ensures secure, efficient, and reliable operation across distributed industrial networks.
