Temperature Controls has just released the state-of-the-art RKC HA 900 series digital PID controllers with a high speed sampling time of 25 ms (0,025 seconds).
This super-fast digital PID controller is suitable for applications requiring fast control response and a high degree of control accuracy. These include RTP (rapid thermal process) and complex process applications such as pH, flow, pressure and level.
The controllers feature a full 5 digit display of both process valve (PV) and set point valve (SV) offering high resolution to 0,1°C for most common thermocouple inputs (11 options) and, 0,01°C for RTD input (DIN/IEC or JIS) options standard process inputs (eight options).
The HA900 series are available in several variants, offering single or dual loop control, conventional PID or PID ramp control, multimemory areas selection, and cascade control.
The multimemory area function allows up to 16 sets of control parameter settings to be stored in memory and selected either from the front face or remotely via digital contact input. 32 segments of ramp/soak function are available utilising the multimemory area.
The HA900 series uses the well-proven 'Brilliant PID' control algorithm with a new power feed forward function, which compensates for power supply fluctuations - which can adversely affect the accuracy of precise temperature and process control applications. Additional output functions include a selection of up to three variable alarm settings, as well as serial communications ports to communicate to host PCs and/or selected PLC devices.
This new high-end product range is a continuing development from RKC, enhancing product features previously found in the REX-F900 and REX-G9 series process controllers, and is a welcome addition to the current product range, offering increased flexibility for the more difficult temperature and process applications.
RKC is a worldwide manufacturer of single and multiloop temperature and process controllers, indicators, recorders and associated sensors and amplifiers, supplying a broad range of markets, in the basic metals, furnace heat treatment, semiconductor, plastics extrusion, injection moulding, scientific, and food and beverage industry.
