Intelligent I/O Controllers vs. Basic Signal Modules

Why upgrading from passive I/O blocks to intelligent edge controllers lowers your Total Cost of Ownership.

Key Advantages of Deploying Valtoris I/O Controllers

Engineered to secure your industrial data and eliminate blind spots.

Extended Reach & Network Flexibility

Bridge connectivity gaps. Deploy wireless remote i/o from local control cabinets via Ethernet to remote solar farms via 4G LTE—anywhere traditional wiring is impractical.

Data Integrity in Noisy Environments

Our modules provide accurate signal acquisition in the presence of strong EMI common to factory floors, utilizing isolated digital i o and robust electrical protections.

Enhanced Protocol Security

We provide a standardized data pipeline with secure protocols like Modbus TCP and MQTT (SSL/TLS) to minimize the risk of unauthorized access.

Simplified Cloud Integration

AOur controllers act as a universal bridge, taking analog (4-20mA) and digital signals and translating them directly into TCP/IP JSON payloads. Future-proofing plug and play.

What Our Clients Say

Learn from system integrators how our I/O controllers simplified their projects.

Massive Wiring Reduction

“We needed to add sensor monitoring on an older production line without shutting it down for weeks to run conduit. The Valtoris 8CH-WF modules were the perfect fit. We mounted them locally, connected the sensors, and they were talking to our SCADA system the same day.”

— Alex C., Automation Engineer, Machinery OEM
Affordable Remote Telemetry

“Monitoring remote irrigation pumps across square miles was a challenge. Cellular data loggers were expensive. We standardized on Valtoris 4G I/O controllers. Now we get real-time status and DO control for a fraction of the cost, and the outdoor reliability is exceptional.”

— Sarah L., Operations Manager, Agricultural Co-op

Expert Guides To Industrial I/O Controllers

How To Choose The Right I/O Controller For Your Application?
  • Connectivity: Ethernet for LAN, 4G LTE for cellular WAN, Wi-Fi for retrofits without pulling new cables.
  • I/O Channels: Define your specific digital and analog I/O needs (e.g., relays, alarms, 4-20mA sensors). Choose 4CH or 8CH density accordingly.
  • Environment: Our -40°C to 85°C rating with electrical isolation covers most heavy industrial settings.
What Are The Key Advantages of Intelligent I/O vs. Basic Modules?
  • Distributed Intelligence: Do data pre-processing (pulse counting, DO hold state) at the edge, which reduces load on your central PLC.
  • Network Native: Designed to be directly integrated with IP networks (MQTT / JSON) without legacy serial bottlenecks.
  • Lower TCO: Save big on heavy copper wiring, engineering time and maintenance overhead.
What Support & Customization Options Does Valtoris Offer?
  • Pre-Sales Consulting: Help with model selection, AI/DI channel mapping, and network design.
  • OEM/ODM Services: Custom firmware for a specific IO control device, tailored I/O channel combinations, or a bare industrial control board to meet your exact project specifications.
  • Long-Term Support: Full VirCom configuration tools and product lifecycle coverage.

Frequently Asked Technical Questions

Q1: Can the Analog Inputs (AI) handle standard industrial 4-20mA sensors?

A: Yes, our 8-channel models are 4-20mA, 0-5V and 0-10V analog inputs ready. The module has a built-in software filtering algorithm to counteract the electrical noise, which is common in industrial environments. Additionally, our VirCom utility enables AI zero point and span calibration directly on the device, giving your SCADA system very accurate telemetry without external signal conditioners.

Q2: If the 4G LTE or Ethernet connection drops, will my Digital Outputs (DO) go out of control?

A: No. Valtoris Intelligent I/O controllers feature a safety mechanism for your Relay input output called DO Hold/Power-on State. If the network heartbeat is lost, the controller will autonomously force the relay outputs into a pre-configured safe state, protecting your machinery during communication failures.

Q3: Can I use the Digital Inputs (DI) to count pulses from a water or gas meter?

A: Absolutely. Our controllers do not just read “High/Low” states. They feature built-in hardware counters on the DI channels. They can actively count high-frequency pulses from utility meters and store the 32-bit count value locally. Your SCADA system can then poll this accumulated value via Modbus TCP at its own pace, ensuring zero missed pulses even if network latency is high.

Q4: I want to send sensor data to Azure/AWS via MQTT. Do I need to buy a separate edge gateway?

A: No. A common frustration is being forced to buy an expensive PLC just to bridge a basic Ethernet remote I/O module to the cloud. Valtoris MQTT-enabled modules (like the 8CH-LTE and 8CH-WF) act as direct-to-cloud nodes, converting signals locally and publishing JSON payloads directly to your MQTT broker over SSL/TLS.
