Overview
The switching output isolated safety barrier drives the on-site intrinsically safe equipment in the hazardous area through the contact switch and logic level signal control in the safe area. Thereby controlling solenoid valves, sound and light alarms, etc. The signal status indicator light is set in red and yellow colors, the alarm displays red, and the output solenoid valve and other working tasks display yellow.
This product needs to be powered independently, and the power supply, input and output terminals are isolated between each other.
