TSP-CO Industrial Carbon Monoxide (CO) Transmitter & Staged Fan Controller
Industrial-grade electrochemical CO gas transmitter and demand-controlled ventilation (DCV) controller. Features a Japanese Figaro electrochemical sensor (>5-year life), selectable 0–500 ppm range, dual 5A relay outputs for staged or two-speed exhaust fan activation, 16-bit analog output (0–10V/4–20mA), RS-485 Modbus RTU, OLED display, and EN50291/UL2034 alarm presets.
SRE-Control Engineering & Technical Overview
The TSP-CO Series is an industrial-grade carbon monoxide transmitter and staged ventilation controller engineered specifically for underground parking facilities, multi-level garages, enclosed loading docks, and commercial building management systems (BMS/BAS). Powered by a world-class Japanese Figaro electrochemical CO sensing cell in a replaceable module architecture, it delivers exceptional measurement repeatability and long-term stability (±5% over 900 operating days).
Designed for autonomous or networked demand-controlled ventilation (DCV), the TSP-CO incorporates up to two heavy-duty dry-contact relays (5A @ 230VAC / 30VDC resistive load) capable of direct staged switching of exhaust fans or dual-speed ventilation motors without requiring external interposing relays. A 16-bit DAC linear analog output (0–10 VDC or 4–20 mA selectable) and an RS-485 Modbus RTU interface (with 15kV anti-static ESD protection) provide comprehensive connectivity to centralized DDC controllers, SCADA platforms, and IoT gateways.
The unit features a crisp OLED screen providing real-time CO concentration, ambient temperature (-5°C to +50°C), and relative humidity readouts. For local safety indication, a three-color status LED (green normal flashing / red alarm threshold) and an internal audible buzzer alert onsite personnel in strict accordance with international standards, including European EN 50291, American UL 2034, and Chinese GB 15322 presets. Its robust flame-retardant PC/ABS enclosure (IP30) and zero-point calibration support ensure trouble-free maintenance across 30-meter detection radii.
