Emerson A6500-RC is a
16-channel output relay module specially designed for critical rotating machinery in plants, featuring high reliability and strong adaptability. Its core function is to work with the
AMS 6500 ATG to build a complete machinery protection and monitoring system compliant with the API 670 standard, and it is widely applied to core equipment such as steam turbines, gas turbines, compressors and hydraulic turbomachinery.
This module can flexibly receive clear, alert or alarm signals from each channel as inputs, and complete configuration through Boolean logic operation, time delay setting and matching output relay selection. Meanwhile, relying on easy-to-operate software, it provides graphical logic display and guides users to complete the configuration process in a visual manner, which greatly reduces the operational complexity.
In addition, as an important component of the AMS 6500 Machinery Health Monitor, it seamlessly integrates into the PlantWeb and AMS software ecosystem. The former enables linkage with the Ovation and DeltaV process control systems to deliver operation-integrated machinery health monitoring; the latter provides maintenance personnel with advanced predictive and performance diagnostic tools, helping to identify machine faults early and accurately and ensuring the stable operation of equipment.

Core Technical Specifications
(1) Digital Inputs
The A6500-RC is equipped with 66 digital input channels, providing ample interfaces for signal acquisition, with the specific parameters as follows: 66 input channels in total; the logic level adopts a graded design – the low level of 0V–3V is the inactive state, and the high level of 13V–32V is the active state, enabling clear distinction between the two states to ensure accuracy of signal recognition; open-circuit input detection is configured as the inactive state; the rated current is 1mA; the rated power is 24mW, featuring a low-power design that effectively reduces energy consumption.
(2) Relay Outputs
The module is integrated with 16 relay output channels of the SPDT (Single-Pole Double-Throw) type, which allows flexible switching of different circuit connection states to meet diverse control requirements. The detailed parameters are as follows: 16 output channels in total; the maximum voltage rating is 32V DC / 48V AC, compatible with the voltage requirements of different devices; the output load covers a variety of application scenarios with high compatibility, specifically AC1: 48V/2A, DC1: 32V/2A, DC-13: 24V/1A, AC-15: 24V/2A; it features short make-and-break time and fast response speed – the normally open (NO) contact is 10ms and the normally closed (NC) contact is 13ms, excluding logic processing time; the rated current is 2A; the rated power is 96W, capable of meeting the control requirements of medium and high-power equipment.
(3) Physical & Mounting Specifications
In terms of dimensions, it adopts a 3U height, 2-slot plug-in design, which halves the cabinet space requirement compared with traditional 6U size cards; it is also a 10TE width module and is only compatible with the A6500-SR rack, with clear mounting compatibility. For the protection class, the conformal coating reaches IP20 in accordance with IEC 60529, which can effectively prevent the intrusion of solid foreign objects and meet the basic protection requirements in industrial environments.
2. Environmental Adaptability
The A6500-RC boasts excellent environmental adaptability and can operate stably in various complex industrial environments, with the specific parameters as follows:Operating temperature: -20°C to +70°C (-4°F to 158°F) with forced cooling, and -20°C to +55°C (-4°F to 131°F) without forced cooling; the operating environment can be flexibly adjusted according to cooling conditions, adapting to different factory temperature control scenarios; storage and transportation temperature: -40°C to 85°C (-40°F to 185°F), meeting the requirements of long-distance transportation and long-term storage; relative humidity: 5% to 95% (non-condensing), enabling stable operation in high-humidity environments without the risk of condensation interference.
Vibration resistance: Compliant with IEC 68-2 Part 6, with an amplitude of 0.15mm at a frequency of 10-55Hz and an acceleration of 20m/s² at a frequency of 55-150Hz, which can effectively resist vibration interference during equipment operation; Shock resistance: Compliant with IEC 60068-2-27, with an acceleration of 150m/s² and the ability to withstand 4,000 shocks per axis, resistant to shocks caused by transportation or accidental collision; Electromagnetic Compatibility (EMC): Compliant with EN50081-1 / EN50082-2, which not only reduces the impact of electromagnetic interference on module operation but also lowers the electromagnetic radiation of the module to surrounding equipment; Maximum power consumption is 6W, adopting a low-power design to reduce the overall system energy consumption.
