INTRINSICALLY SAFE BARRIER

INTRINSICALLY SAFE BARRIER

The ISB10 provides a UL913 intrinsically safe barrier between a 10 channel conductance probe in a hazardous location and pump controls in a non-hazardous area. The Level Probe Barrier is designed to allow the level sense signal (±12 V square wave) from the pump control device to pass through unchanged. If an accident or malfunction occurs in the control panel that would potentially connect spark-inducing energy to the probe wiring in the wet well, the IS Barrier clamps to limit the voltage and current to a safe level. The 10 Channel Probe Barrier has a fuse in each channel that is capable of disconnecting the barrier from a high energy source that may be present in the control panel.
