RKC, a controller specialist, has designed and developed a flexible, compact multizone temperature controller. The Farex-SR Mini system offers a flexible multizone PID temperature controller that serves as a building block for factory automation. This new modular control system provides high performance temperature control that is normally associated with advanced, dedicated discrete controllers.
The mini system is compact, designed with low profile modules that measure 96 x 24 x 100 mm. (Basically the profile of a 3,5" floppy disk.) This small size permits the inclusion of multizone PID temperature control to new equipment, or the retrofitting of existing control panels.
Another advantage of this advanced system, is that it combines a power supply, CPU module and up to 10 I/O modules. Each of these I/O modules offers two zones of PID temperature control, one zone is offered for the heat/cool module. Up to 10 analog and digital input/output modules can be connected to the power or CPU module of one Farex-SR Mini System.
The Farex system's design and its configuration flexibility mean that it can often easily fulfil quite specific installation requirements. Within 10 modules, 20 temperature control zones (two zones per module) can be arranged in a space as small as 96 x 288 x 100 mm. The system is sufficiently compact that it may be stacked to offer a maximum capacity of 320 zones of temperature control, which can be linked to a single operation panel - or PC, as one system.
A versatile 'mother-block' mounting system allows for rapid mounting inside a machine control panel - or positioned to suit individual equipment requirements. A touch screen operational panel permits easy access to all setting functions. The Farex-SR Mini System offers optional 7-segment programmer, advanced control algorithms and optional fuzzy logic.
RS232C, RS485 or RS422A communication links are available to connect the Farex-SR Mini system to a PC or external PLC. PID temperature loops are efficiently processed and controlled. PC accessibility provides flexibility and opens up application possibilities that include factory automation, data acquisition and SPC/SQC analysis. Temperature Controls has the sole agency for RKC in SA.
