The Intrinsically Safe Duplexer (ISD-P, ISD-D, or ISD-S) is a UL913 low cost SCADA ready intrinsically safe pump controller designed to perform level control for duplex lift station applications.
The I.S. Float Input Controller comes in one of three options: Surface Mount, Din Rail Mount, or Panel Mount. The I.S. Level Probe Input Controller comes standard with a serial port and has an optional Ethernet port.
The controller's level inputs may be connected to either five float switches, five single point conductance probes, or five selected points on a ten point conductance probe.
The level inputs are intrinsically safe and allow maintenance personnel to safely handle the float switches or conductance probes while the unit is in operation.
