Yokogawa EB401-10
- Product Introduction: It is a 16-channel digital I/O module for Yokogawa CENTUM VP DCS system, which integrates digital input and output functions, and is used to connect on-site discrete devices (such as valves, pumps, sensors, etc.) and realize signal interaction between the control system and on-site devices.
- Technical Specifications:
- Number of channels: 16 channels (8 digital inputs and 8 digital outputs).
- Digital input: 24V DC, input voltage range 19.2-30V DC, input current ≤5mA, response time ≤1ms.
- Digital output: 24V DC, output current 2A per channel, short-circuit protection function.
Detailed content
-
- Isolation: 500V AC between channels, 2kV AC between input/output and system for 1 minute.
- Working temperature: -20~70°C.
- Connection method: Pressure clamp terminal, easy to wire and maintain.
- Functional Characteristics:
- It integrates input and output functions, which saves the space of the I/O rack.
- The channel isolation design effectively prevents signal interference.
- The digital output has a short-circuit protection function to protect the module and on-site equipment.
- It has a self-diagnosis function to detect channel faults in time.
- Application Scenarios: It is widely used in petroleum chemical industry, chemical industry, power plant, and other industries, and is used for on-site equipment status monitoring (such as valve opening and closing status, pump running status) and logic control (such as starting and stopping pumps, opening and closing valves), ensuring the stable operation of the production process.
