Ad11 Dc Voltage Transducer With Rs485 Rs232

The CE-AD11 series is a one-element DC multi-parameter digital transducer designed for measuring DC current, voltage and power in industrial monitoring and control systems. Two part numbers are offered: the CE-AD11-34MS3-0.5 with 0 to 500 VDC input range, and the CE-AD11B-37MS5-0.5 with 0 to 1000 VDC range, both accepting 0 to 5 ADC current input from a mating Hall effect analog transducer. Output is digital data via RS-485 interface using MODBUS protocol, with selectable baud rates from 1200 to 19.2K bps and a 100 ms refresh period. Accuracy is rated at 0.5% for both variants, with the MS3 powered from +24 VDC and the MS5 from a wider +9 to 55 VDC supply.

The transducer uses a fixed case style (S3 for MS3, S5 for MS5) with no window, and draws no more than 500 mW under static conditions. Input overload withstand is two times full span for one second, repeatable up to ten times. Isolation between input and output exceeds 2500 VDC, which is standard for equipment intended for electrical distribution and railway electrification environments. The operating temperature range spans 0 to 50 degrees Celsius, with storage rated from -55 to +85 degrees Celsius. These specifications reflect typical practice for panel-mounted industrial transducers in power monitoring applications.

Target buyers include system integrators building digital data acquisition platforms, automation engineers designing electrical distribution monitoring, and project teams working on process automation or railway electrification. The RS-485 MODBUS output allows direct integration with PLCs, SCADA systems and energy management software without additional analog-to-digital conversion. Buyers should confirm with CQ Bluejay whether the mating Hall effect current transducer is included or must be sourced separately, and verify the required supply voltage for their chosen model. Both variants ship from Jiangbei District, Chongqing.

CQ Bluejay is located in Jiangbei District, Redstone Road, Chongqing 400020, China. The supplier is listed under the harbor trust tier with a response rate of 0.00 and zero recorded average response hours, which indicates limited or no recent buyer engagement data is available through the profile. No information is provided about year of establishment, registered capital, factory size, or employee count, so these details cannot be stated. The listing focuses on industrial measurement and control components, specifically voltage and current transducers for power system monitoring.

The supplier's product range on this listing centres on the CE-AD11 series digital transducer, with no additional catalogue items described. There is no mention of ISO certification, quality management systems, export licence details, or key client references. Buyers should treat the technical specifications as the primary basis for evaluation and conduct independent supplier verification before placing orders. The Chongqing location may be relevant for logistics planning, though the listing does not specify preferred ports or incoterms.
