DS3800HPRB1D1C

HS Code: 85423990 (for customs reference only)
Operating Temperature Range: 0 °C to +60 °C; storage temperature ranges from -40 °C to +85 °C, relative humidity 5 %-95 % non-condensing
Power Supply: Powered via rack backplane, working at +5 VDC logic power, typical power consumption 12 W.
Input Specification: Single-channel differential pulse rate input; accepts variable frequency pulse signals from magnetic speed sensors; input voltage range 0-24 VDC; frequency measuring range configurable by onboard jumpers.
Output Specification: Digital data output transmitted through backplane bus to main CPU of Mark IV system; no external physical analog output terminals.
Main Characteristics & Function: It captures pulse signals from field transducers and performs high-precision frequency-to-digital conversion to provide real-time rotating speed and pulse-based flow measurement values for turbine control logic. Twelve configurable jumpers together with one trimmer resistor allow field technicians to adjust measuring range and signal threshold according to on-site sensor parameters. Gold-plated edge connectors ensure stable electrical contact with system backplane. On-board integrated circuits handle pulse counting and interrupt triggering for speed-related protection and control algorithms. It supports rack-mount plug-and-play installation with retention levers for mechanical locking. Built-in circuit protection improves anti-interference performance under industrial cabinet environments. No front-panel display, all measured data is retrieved through the main control system. It works cooperatively with other DS3800 series boards to complete turbine closed-loop control and machinery monitoring functions. Electro-static discharge protection measures are mandatory during module replacement because internal timer and interrupt controller chips are vulnerable to static damage.
