RKC has produced new digital control modules known as the SRV and SRX Series.
SRV series
Dual loop control modules have been used to keep the control system at a reasonable cost, and the instrument handles up to 62 temperature control loops.
The series has also been designed keeping the environment in mind, this is achieved by the use of newly designed power supply and control circuits, which reduce the unit's power consumption. And because there is less heat generation, it is easier to limit temperature increase inside the control panel.
There is less wiring because installations separated by control zones are possible. The wiring to sensors and output devices can now be minimised. The modules can be installed separately inside a control panel or machine to reduce the physical size of the housing. The modules are designed around human safety and are easy to use. The hinged terminal cover is standard, and there is interleave terminal arrangement for easy wiring.
With the system configuration there is the basic type and an extension type that is for heating only (The V-T10-A and the V-T10-B, respectively). They have similar control functions and specifications, and they can accept a maximum of two inputs. The V-T10-C and the V-T10-D are the basic type and extension type with heat/cool function. They both have single inputs.
SRX series
This series is supplied with high-resolution input and parameters settable in 1/100 second for process applications with fast response. Applications in Rapid Thermal Process (RTP) in semiconductor manufacturing processes, which were difficult to handle with the usual conventional controllers, can now be solved. Examples of these difficult manufacturing processes would include pulse heat temperature control of flip chip bonders, and lamp annealing with halogen lamps. Other applications include pressure, flow rate and other process control applications.
Dual loop control can be performed with a single compact module. Power supply and communication lines are via a connector on the side, so no wiring is required. The unit may be controlled via RS485, this allowing multizone distributed control system in a compact size. Control can be selected from a standard fixed set point control and ramp/soak program control. This program control of 16 segments and 16 patterns is supplied as a standard feature of this series.
