Specifications of Pump Controllers
Specifications for pump controllers include a number of inputs, number of outputs, input types, output types, and number of zones (if applicable).
The number of inputs equals the total number of signals sent to the controller.
The number of outputs equals the total number of outputs used to control, compensate or correct the process.
Input types include direct current (DC) voltages, current loops, analog signals from resistors or potentiometers, frequency inputs, and switch or relay inputs.
Output types include analog voltages, current loops, switch or relay outputs, and pulses or frequencies.
Pump controllers can also send inputs or receive outputs in serial, parallel, Ethernet, or other digital formats which indicate a process variable. Some pump controllers send or receive accept commands and inputs from information converted to an industrial Fieldbus protocol such as CANbus, PROFIBUS®, or SERCOS, or other industrial automation protocol. PROFIBUS is a registered trademark of PROFIBUS International.
