LU-BK11 Digital Output Isolation Safety Barrier (1 In / 1 Out) Safety Barriers

LU-BK11 Digital Output Isolation Safety Barrier (1 In / 1 Out)

The LU-BK11 safety barrier controls field devices in the hazardous area via switch, transistor or logic-level signal input from the safe area, and is suitable for driving solenoid valves, alarms and other intrinsically safe devices without energy storage. It is powered by an independent DC supply with isolation between supply, input and output, and includes high/low output status indicators. The compact, lightweight design allows high-density installation.

LU-AK22 Digital Input Isolation Safety Barrier (2 In / 2 Out) Safety Barriers

LU-AK22 Digital Input Isolation Safety Barrier (2 In / 2 Out)

The LU-AK22 safety barrier receives switch contact or proximity sensor signals from the hazardous area and, after isolation, transmits them to control systems or other panel instruments in the safe area via relay contact (level signal or transistor) outputs. It is powered by an independent DC supply with isolation between supply, input and output.

LU-AB22 Detection-End + Operation-End Isolation Safety Barrier (2 In / 2 Out) Safety Barriers

LU-AB22 Detection-End + Operation-End Isolation Safety Barrier (2 In / 2 Out)

The LU-AB22 safety barrier converts DC signals into isolated standard process signals and limits hazardous energy from entering the hazardous area through the intrinsically safe terminals. It has two independent input and output channels, each magnetically isolated between input, output and power supply. Channel 1 accepts 4-20mA, 0-20mA or 0-10mA current input with a distributor voltage of at least 16VDC.
