- AO5024 operating terminal switch output isolated safety barrier (one in, one out)
Performance Overview
Drive intrinsically safe low-power equipment in hazardous areas by controlling the output through dry contacts, collector open circuit signals, or logic level signals. Intrinsic safety equipment such as solenoid valves, sound and light alarms, etc.
Three party isolation of input, output, and power supply terminals.
Usage environment
Working environment temperature: -20 ℃ to+60 ℃
Allowable relative humidity at work: 10% RH to 90% RH (40 ℃)
Allowable atmospheric pressure during work: 80kPa~106kPa
Allowable ambient temperature during storage and transportation: -40 ℃ to+80 ℃

Technical Specifications
Explosion proof grade: [Exia] IIC
Safe zone allows input signal: dry contact collector open circuit signal
Logic level: When 5V~30V, it indicates "on" and supplies power to the on-site equipment
When 0V~1V, it means "off" and stops supplying power to the on-site equipment
Output signal to danger zone: digital output drives solenoid valve or alarm
Large output voltage: 22V Small output voltage: 12V
Current limit: 45mA
Dielectric strength: ≥ 2500V AC (between input/output/power supply, leakage current 1mA, testing time 1min)
Insulation resistance: ≥ 100M Ω (between input/output/power supply)
Electromagnetic compatibility: EMC complies with IEC61000-4
Certification parameters of National Quality Supervision and Inspection Center for Instrumentation and Electrical Products (CQST): Terminal to Terminal: Um=250V AC/DC
