ST-CW880B Wireless Temperature Centralized Host (New)

Overview: The wireless temperature monitoring host is a field temperature monitoring instrument that integrates monitoring of temperature sensor working status, on-site temperature display, alarm indication and output, event recording, and data recording. It can also modify the address and other parameters of on-site wireless temperature sensors. Technical Parameters: Technical Parameter | Specification Wireless Frequency | 433MHz Number of Wireless Sensors Managed | ≤252 Communication Interface | RS485 interface, communication distance ≤1200m (without relay) Number of Networked Hosts | ≤128 sets Communication Protocol | Modbus protocol 'Wireless Temperature Monitoring System Communication Protocol' Baud Rate | 1200, 2400, 4800, 9600, 19200bps optional Temperature Alarm Value | Upper limit: +90℃, lower limit: -20℃ Temperature Warning Value | Upper limit: +60℃, lower limit: -10℃ Warning Voltage Value | 2700mV Relay Dry Contact Parameter | AC220V/5A (1 group of NO/NC contacts) Working Voltage | AC85~265V/DC110~370V Overall Power Consumption | ≤5VA Working Temperature | -10℃~+70℃ Working Humidity | ≤90%RH, no condensation, non-corrosive Altitude | ≤2500m Case Dimension | 162*150mm Insulation Resistance | ≥100MΩ (temperature 10~30℃, RH <80%) Installation | Wall-mounted/embedded Main Functions: Function | Description Receive Data | Receives temperature and sensor operating voltage uploaded by wireless temperature sensors Display Data | Color displays received data with intuitive effect; backlight switch is controllable, suitable for various application scenarios Clock Display | Real-time clock display serving as time reference for event records Parameter Setting | All parameters are flexibly configurable, easy to operate, data not lost during power failure Alarm Output | When an alarm event occurs, relay dry contact signal outputs and buzzer alarm sounds Temperature Alarm Record | Records the temperature, start time and end time of the temperature measurement position where alarms have occurred, up to 200 records can be saved; when exceeding 200 records, automatically overwrites the earliest record Password Management | Password management is adopted; password must be entered when setting parameters; passwords are divided into user password and system password; entering system password enables more advanced setting functions Product Drawing: Product Construction Drawing:
