Hitachi LYA010A 8-channel analog input module (AI card)

Hitachi LYA010A 8-channel analog input module (AI card)

LYA010A is an analog input module (AI card) for Hitachi LY/H-5000M DCS system, which is matched with the corresponding terminal board for use.
The function of LYA010A is to collect analog signals such as 4-20mA and 0-10V output from field transmitters, filter, isolate, and AD convert the signals, convert process parameters such as temperature, pressure, liquid level, and flow rate into digital signals, and upload them to the main control CPU; Provide control system for adjustment calculation, parameter display, over limit alarm, and interlock protection. LYA010A is the core I/O card for collecting process analog quantities in process industry DCS systems.

Product features

1.  8 analog acquisition channels, supporting both current and voltage commonly used transmitter signals, suitable for the vast majority of field instruments.
2. 12 bit AD conversion with an accuracy of ± 0.2% FS, meeting the requirements for precise acquisition of process parameters.
3.  Grouping isolation design to suppress common mode interference on the field instrument side and avoid interference from entering the backplane bus and affecting the main control.
4.  The hardware filtering parameters can be configured to effectively suppress high-frequency noise on site, suitable for power plants and chemical sites with strong electromagnetic interference.
5.  Equipped with signal over range and under range diagnosis, it actively reports faults when the transmitter is disconnected or the signal is abnormal.
6. Equipped with TA010A terminal board, the instrument wiring is centralized, and there is no need to repeatedly move the on-site cables when repairing or replacing the cards.
7.  The circuit board is coated with three anti coatings to prevent moisture, dust, and condensation, and is suitable for harsh working conditions inside the control cabinet.
8.  The panel operation indicator light is intuitive, making it convenient for operation and maintenance personnel to quickly determine the power supply, communication, and fault status of the card.
9.  Fully compatible with DI/DO cards and CPUs of the same series such as LYD000A and LYD105A, with simple configuration.
10.  Classic discontinued spare parts, a large number of old Hitachi H-5000M DCS devices are in use in China, and there is a high demand for maintenance and replacement.
