RKC Instrument has designed a multiloop digital temperature controller that can control up to a maximum of eight channels in a compact ¼ DIN size.
The MA900 increases zone density and makes smaller numbers of loops affordable, yet still holds many of the advantages that a single loop controller might offer. This unit will aid designers of control equipment by saving labour costs, installation costs, electric panel sizes and operation costs.
The controller has a variety of optional functions. An optional communications interface, RS232C, RS422A or RS485 is available for networking to computers, PLCs and scada software. Modbus or ANSI (RKC standard) protocol can be selected. Four channels of temperature controls are packed into 96 x 96 x 100 mm case, which reduces your panel cutouts and makes the panel board smaller. Up to eight kinds of combinations of temperature set value, PID constant, alarm set value, etc, for each channel can be registered as 'memory area'. The controller comes with an optional heat/cool control, digital contact input, multiple of alarm functions, close horizontal mounting and waterproof and dustproof protection for operation in severe environments or when wash-down is required.
