Description
BPC-94 is an advanced PID controller with two control loops (heating / cooling), supported by the auto-tuning function and Fuzzy-Logic algorithm. The device has a build-in REL / OC (SSR) and / or analog output, according to the customer selection: active current output, passive isolated current output or active voltage output, which can be used in the process of control. The BPC-94 controller is equipped with one universal input, type: 0/4-20 mA, 0-10V, 0-150 mV, Pt 100/500/1000 or TC (K, S, J, T, N, R, B, E). During the measurement process only one kind of input is available. Cold junction of thermocouple sensor is compensated automatically. RTD and TC inputs feature with fully linearized characteristics. Thanks to wide range of characteristic curves (linear, square root, quadratic, user-defined and volume characteristic for cylindrical tanks) the controller may be used in various process control systems. The 24V DC / 100 mA output is designed to supply measuring transducers, and the RS-485 port enables data transmission in production process monitoring systems. The controller can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
