High QualityYokogawa ASD533 DCS Module
Overview
1. Power supply
Power supply for processor, memory and logic of the loop processor board.
2. Control logic
Control logic for activation and blocking of hardware signals to the back plane. LEDs for indication of status and communication are also controlled in this block.
3. LED indications
LEDs for indicating status of fire, fault, communication and voltage.
4. Drivers
Drivers for adapting hardware signal to the back plane.
5. CPU/Memory/watchdog
This is the main block of the SPK-2 board. The CPU controls both of the detector loops and the communication with the LPK-2. The memory circuits contain the programme code, default data for the detectors and status information. The watchdog supervises the processor and checks for hang-ups in the programme execution.
6. Address switch
The 8-bit address of the SPK-2, i.e. the loop number, is set with the DIP switch.
7. LPK communication
Interface for back plane communication.
8. DC/DC converter
The DC/DC-converter converts the battery voltage from the back plane to 30 VDC, for the detector loops.
9. Signal filter
Signal filter for the communication signals.
10. Communication direction switch
For closed loops the choice of direction for the communication is made with this switch.
