Modular Control System
July 1, 2007
RKC InstrumentThe SRZ DIN rail-mounted, high-density modular system has a sample cycle time of 250 ms and accuracy of 0.2%. Control method is selectable between position-proportional control and cascade control, in addition to the typical heat-only and heat/cool methods. True universal input includes 10 thermocouple types, RTD, voltage or current. A single module may provide up to four channels of heat-only or two heat/cool, of which up to 16 modules can be connected. Four assignable CT inputs are provided for HBA, including three-phase. Numerous alarm choices include loop break alarm and alarm network. The SRZ is designed for mounting on the inside of an instrument panel to save space and to replace banks of discrete temperature controllers.
