Honeywell FC-SAO-0220M Conformal Coated Safe Analog Output Module
Product Short Description
Technical Specifications
Power Supply Parameters: It requires dual power inputs including 5VDC and 24VDC. The 5VDC power input consumes 30mA current, while the 24VDC input consumes 65mA current plus an additional 30mA for each active output channel.
Output and Signal Specifications: It has two galvanically isolated output channels, each fitted with a 12-bit D/A converter for output and a 12-bit A/D converter for output value verification. The output supports both active and passive 0 – 20mA or 4 – 20mA current signals, with an off current of less than 0.05mA. The maximum loop resistance reaches 600Ω under active loop powering, and the maximum output voltage is 30VDC. Under passive external powering, it supports a maximum of 40VDC and a minimum voltage drop of no more than 7.5VDC.
Physical and Installation Requirements: It requires an installation space of 4 TE and 3 HE. It only works with resistive or capacitive loads, and inductive loads will trigger fault alarms. The 0V1 and 0V2 pins on the module are interconnected to ensure stable circuit operation.
Certifications and Additional Parameters: It has obtained CE, TÜV, UL, CSA and FM certifications. The watchdog input current is fixed at 0.5mA, and it conducts accuracy diagnostics for output values within a ±5% range during the configured test interval.
Dual-Converter Design for Precise Signal Control: Each channel combines 12-bit D/A and A/D converters. The D/A converter ensures accurate analog signal output, while the A/D converter real-time reads and verifies the output value, which guarantees that the output current stays within the set error range and maintains high control precision.
Comprehensive Fault Diagnostics and Protection: It performs regular diagnostics on key performance indicators including output value accuracy, de-energization capability and cross-talk between channels. The watchdog and processor can independently de-energize outputs when faults are detected, and galvanic isolation prevents interference between the output channels and power supply to avoid system malfunctions.
Conformal Coating for Harsh Environment Adaptability: As a conformal coated module, it has stronger resistance to moisture, dust and chemical corrosion compared with non-conformal coated versions. This structural advantage enables it to operate stably in harsh industrial environments and extends the service life of the module.
Flexible Adaptation to Different Powering Modes: It supports both active and passive output modes to match different field device power supply requirements. The compatibility with a maximum 600Ω loop resistance under active mode and 40VDC external power under passive mode allows it to integrate into various industrial control circuit configurations.
Application Scenarios
Petrochemical Processing Plants: It is applied in the control systems of chemical reactors, distillation columns and pipeline flow control valves. It outputs precise 4 – 20mA signals to regulate the opening of control valves and the speed of pumps, ensuring stable material ratios and flow rates during chemical reactions and preventing safety hazards caused by abnormal process parameters.
Thermal Power Generation Systems: It is used in boiler combustion control and steam pressure regulation systems. It transmits analog signals to adjust the feed rate of coal powder and the air supply volume, and maintains the stability of boiler combustion and steam pressure. This optimizes power generation efficiency and avoids equipment damage due to extreme pressure fluctuations.
Pharmaceutical Production Lines: It is deployed in temperature and pressure control links of pharmaceutical reaction kettles and sterile mixing equipment. Its high-precision signal output ensures that the temperature and pressure in pharmaceutical production processes strictly comply with process standards, which guarantees the quality uniformity of pharmaceutical products and meets the strict requirements of pharmaceutical industry regulations.
Water Treatment Plants: It is integrated into sewage treatment aeration systems and chemical dosing systems. It controls the aeration rate by outputting analog signals to adjust the speed of aeration fans, and regulates the dosage of flocculants and disinfectants through connecting with dosing pumps. This enhances sewage treatment efficiency and ensures that the treated water meets discharge standards.
