HITACHI LYD000A is a digital input (DI) control module in Hitachi's DCS/PLC system. The following are detailed parameters and functional descrtptions:
Core parameters
Type: Digital Input (DI) module, used to collect switch signals (such as binary signals for buttons, limit switches, etc.) from industrial sites.
Working voltage: usually 24V DC (to be confirmed with specific systems), suitable for the standard input level of DCS/PLC systems.
Number of input channels: The specific number of channels is not clearly disclosed, but similar DI modules are generally configured with 8/16/32 channels, which should be based on the product manual.
Response time: millisecond level, meeting the real-time control requirements of industry.
Isolation method: Optoelectronic isolation may be used between channels or between channels and systems to enhance anti-interference capability.
Environmental adaptability:
Working temperature: usually -10 ℃ to+55 ℃ (industrial standard).
Humidity: 5% to 95% RH (no condensation).
Functional Features
Signal acquisition: Convert the switch status of on-site equipment into digital signals recognizable by PLC/DCS.
Filtering processing: Built in hardware or software filtering to eliminate signal jitter and improve stability.
Diagnostic function: Supports channel fault detection (such as disconnection and short circuit) for easy maintenance.
Compatibility: Compatible with Hitachi H series or corresponding DCS/PLC architecture, supporting standard communication protocols (such as Modbus, Profibus, etc., specific model needs to be confirmed).
Application scenarios
Power industry: switchgear status monitoring, protection device signal acquisition.
In the field of chemical engineering: valve opening and closing feedback, equipment start stop signal connection.
Petroleum industry: monitoring of pump station operation status and safety interlock system.
