ISD-P Intrinsically Safe Duplex Pump Controller - Conductivity or Float Input


Price: $1,178.00
Manufacturer: MPE
Manufacturer Part No: ISD-P
The Intrinsically Safe Duplexer, ISD, is a low cost SCADA ready intrinsically safe pump controller designed to perform level control for duplex lift station applications. The controller's level inputs may be connected to either five float switches or five single point conductance probes. 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. The unit provides a 10 second power-up start delay, a 5 second lag pump delay, and duplex alternation. The unit has LEDs that show power on status, level input status, pump call status, high & low alarm status, and level input out-of-sequence indication. Relay contacts are provided for the pump 1 & 2 call, and high & low level alarm outputs. Toggle switches allow the operator to set the Hand, Off, or Auto mode for each pump, to select automatic alternation, or to set one pump as lead. Level simulation (Push-to-Test) is accomplished by pressing and holding the push-button. Releasing the push-button allows the simulated level to return to normal. The high level status indication latches upon high level, until reset by pressing the reset push-button\r\n(the high level relay does not stay latched. The out-of-sequence logic detects when the inputs fail to close in the correct order. The logic also compensates for most out-of-sequence conditions and allows for continued pump operation. Connecting the RS-232 serial port (or optional Ethernet Port) to a SCADA system allows the lift station to be monitored and controlled remotely. Additional setup and troubleshooting features are available using the separately supplied Touch Screen Interface Device (TSID).\r\n120 VAC Input, UL913, Panel Mounting
