从China供应商批发进口Alarm Control Cabinet — FOB条款

This alarm control cabinet from Xi'an Hua Fan Instrument Co., Ltd. is a wall-mounted signal conditioning and alarm unit designed to interface with 4-20 mA transmitters. The unit measures 380 mm by 210 mm by 83 mm and weighs approximately 2.5 kg, operating on AC 220 V at 50 Hz to deliver DC 24 V output with over-current protection. It accepts one or two channels of two-wire, three-wire, or four-wire bus transmitter signals, providing direct display of measured values across a programmable 0 to 9999 range with an 8-second response time.

The enclosure is built for industrial environments with a temperature operating range of -10 to 50 degrees Celsius and humidity tolerance of 15% to 70% RH without condensation. Output control is handled through relay switch outputs rated at AC 250 V 10 A and DC 30 V 10 A, with 1-2 alarm control relay outputs available. The audible alarm exceeds 90 dB, suitable for noisy plant conditions. Standard industrial practice for such cabinets includes IP ratings for dust and moisture ingress, though buyers should confirm the specific rating with the supplier.

This instrumentation cabinet suits process control rooms, manufacturing facilities, and environmental monitoring stations where transmitter signals require local display and alarm functionality. Typical buyers include system integrators, plant engineers, and maintenance contractors in the chemical, pharmaceutical, and utilities sectors. The two-wire and three-wire compatibility reduces wiring complexity for legacy retrofit projects. Importers should confirm whether the unit is supplied with terminal blocks, mounting hardware, and a user manual in English.

Xi'an Hua Fan Instrument Co., Ltd. is based at No.205 Jinhua North Road, Xiaan, Shaanxi Province, China, postal code 710032. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00% and an average response time of 0 hours, which indicates that response data is either not yet collected or not currently active. No imported supplier tier is indicated, suggesting the profile is domestically registered within the Chinese marketplace.

The company evidently operates from the industrial city of Xi'an, a hub for instrumentation and aerospace manufacturing in northwestern China. The listing provides no information about factory size, year of establishment, revenue, export markets, or specific certifications held. Buyers should verify ISO 9001 or equivalent quality management certification directly with the supplier, along with any CE marking or防爆 (explosion-proof) ratings if required for their application.
