1、 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.

2、 Technical parameters

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

High 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): between terminals 9 and 10; 11. Between 12 terminals: Um=250V AC/DC

Uo=25.2V，Io=109mA，Po=687mW
