Process Controller

We have different models with different configuration which can be programmed as
per customer requirements.
number of inputs : up to 8
it can be dc voltage input / 4 to 20ma / 0 to 20ma / 12 vdc / 24 vdc / potential free contact.
number of outputs : up to 8.
relay output / rs232.
number of inputs : the number of inputs is the total number of signals sent to the controller. This number includes process variable signals such as temperature, pressure, level, speed, etc., and status inputs such as on/off.
number of control outputs : the number of control outputs is the total number of outputs used to control, compensate or correct the process. This number relay outputs as well as switches and rs232 serial pot .which activate or deactivate control devices.
controller inputs :
dc voltage input: controllers accept analog dc voltage inputs such as ±5 v, 0 -10 v.
current loop (transmitter) input: current loop (transmitter) inputs include analog inputs such as 0 - 20 ma and 4 - 20 ma. Or any other current-loop signal from a transmitter.
resistive / potentiometer input : controllers accept analog inputs from a resistor or potentiometer which monitors the process variable(s).
frequency input: a pulse or frequency input is used to measure and indicate a process variable for feedback to the controller.
switch / relay input: controllers accept a discrete, on/off voltage signal from a sensor or switch which monitors the process.
control signal output:
analog voltage: controllers produce analog dc voltage outputs such as ±5 v, 0 - 10v.
switch / relay output / rs232: the output is a switch or relay that can be "on" or off".
general applications : control, monitor or record temperature, pressure, flow, production, totalizing and storing based on preset timing or real time clock through rs232 communication pot to save energy, time and man power to always increase the production capacity with lesser wastage in more ways.
