Description
Product Specification: YOKOGAWA VF701 Digital Input Module
The YOKOGAWA VF701 is a high-performance digital input module designed for industrial automation systems, offering reliable signal acquisition and control in demanding environments. Engineered for compatibility with Yokogawa’s distributed control systems (DCS), this module supports 16 channels of 24V DC input signals with advanced noise isolation, making it ideal for integrating switches, sensors, and relays into critical processes.
The
VF701 module is optimized for industrial applications requiring precision and durability. Key features include:
- 16-Channel Capacity: Simultaneously processes up to 16 digital input signals.
- Galvanic Isolation: 2.5kVrms protection against voltage surges and electromagnetic interference (EMI).
- Wide Voltage Tolerance: Accepts 24V DC ±20% input, ensuring compatibility with diverse sensors.
- Fast Response Time: ≤1ms signal detection for real-time system responsiveness.
- LED Diagnostics: Provides visual status indicators for each channel, simplifying troubleshooting.

The VF701 outperforms alternatives in key areas:
- Higher Isolation Voltage: 2.5kVrms vs. typical 1.5kVrms in comparable modules.
- Faster Response: ≤1ms vs. 2–5ms response times in competing products.
- Extended Temperature Range: Operates in -40°C to +70°C vs. 0°C to +50°C for most rivals.
-
- Channel Density: Choose 16-point modules for high-density applications or 8-point modules for smaller systems.
- Voltage Compatibility: Verify input voltage matches your sensors (e.g., 24V DC).
- Safety Compliance: Opt for redundant modules in SIL 3-rated safety systems.
-
Wiring: Use shielded cables to minimize EMI interference.
-
Voltage Check: Ensure input voltage does not exceed 28.8V DC to prevent module damage.
-
Installation: Avoid mounting in environments with high humidity or corrosive gases.
-
Maintenance: Regularly inspect LED indicators for channel status and system health.
