1、 Performance Overview

The NAMUR proximity switch signal in the hazardous area is isolated and converted to output to the safe area. The output mode is open collector output, and inversion selection can also be performed.

The input terminal, output terminal, and power supply terminal are isolated from each other, and have the function of detecting line faults.

2、 Technical parameters

Explosion proof grade: [Exia] IIC

Dangerous area allows input signal: NAMUR proximity switch

Active signal trigger point: When the input signal is greater than 2.1m Α, it is indicated as "ON"

When the input signal is less than 1.2m Α, it is indicated as "OFF"

Line fault detection function (LFD): If the input current is less than 50 μ A, it is judged as input disconnection

Input current>6mA, judged as input short circuit

Output signal to safe zone: open collector

Short circuit current: about 8m Α Open circuit voltage: 8V

Current output: ≤ 40mA Short circuit current:<100mA

External input voltage: 40V DC Switching frequency: ≤ 5kHz

Input and output are reversed control settings: K1 is set to the ON side, and the input and output of the corresponding channel are reversed.

K1 is set to side 1, and the input and output of the corresponding channel are in phase.

K2 is set to the ON side and does not include a disconnection alarm output function (no LFD function).

K2 is set to 2 sides and includes a disconnection alarm output function (including LFD function).

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): Um=250V AC/DC
