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 circuit output with two collectors, and can also be selected for reverse phase.

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"

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

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

Current output: ≤ 40mA

External high input voltage: 40V DC

Short circuit current:<100mA

Input and output are reversed control settings: K1 and K3 are set to the ON side, and the input and output of the corresponding channel are reversed.

K1 and K3 are set as side 1, and the input and output of the corresponding channels on side 3 are in phase.

K2 and K4 are set to the ON side without LFD function.

K2 and K4 are set to 2 sides, with LFD indicator function on 4 sides.
