Powerful measuring amplifier
The heart of the system is the functional amplifier permitting different controller functions. It is programmed exactly for the required application and can immediately be used for numerous functions. The measuring amplifier can be built into existing cabinets or wall casings. Its common format of 96x96 mm fits into each cutout dimension. At any time, the system provides information on the measured concentration, the limits when exceeding them or falling below and on the respective operating conditions. The individual system settings and the service settings are password-protected against unauthorized access.
Flexible control
A total of 4 relays is available to control pumps, valves and other subassemblies. Thus, the exact dosage of chemicals can be controlled. In addition, 2 analogue outputs (4-20 mA) provide a safe transmission of the measured values for further evaluation. The controller has a variety of control variants such that no further regulators are required. The following functions can be assigned to the relays: ON / OFF; exceeding / falling below limits; PWM controller; PFM controller. mA output: linear range, proportional controller.
