SW series Digital Temperature Controller DATA SHEET SW49 is an extremely compact temperature controller which has 48 x 96 mm front panel with a large, white LCD and 58mm depth behind panel. Developed as a successor to the standard model SY, SW49 features fast sampling speed (50 ms), highly accurate input indication, and universal input, in addition to various functions of SZ, while achieving a competitive price. Equipped with multiple input/output and sophisticated control functions, SW49 serves as a suitable temperature controller for a wide range of use. 1. Enhanced control performance which makes SW49 suitable for a wide range of application • Fast sampling speed of 50 ms (SY49: 500 ms) • Improved input indication accuracy For example: indication accuracy when measuring around 0.0°C by using type K thermocouple of which measuring range 0.0 to 400.0°C: ±1.1°C (cf. SY49: ±3.1°C) • Freely configurable control cycle (100 ms to 99 s) • Control method selectable among 7 types (ON/OFF control, PID control, fuzzy PID control, selftuning control, PID2 control, 2-degrees-of-freedom PID control, motorized valve control (with position feedback input)) 2. Any type of input can be accepted • Universal input is supported (thermocouple, RTD, voltage, current) • Control output is selectable among 4 types (Relay contact, SSR drive, current linear, voltage linear) The following optional functions can be incorporated: • Up to 3 digital inputs and 5 digital outputs • Remote SV input, analog re-transmission output • Motorized valve control output (with position feedback input) • Current monitoring using CT 3. Easy-to-see clear display and user-friendly interface • Wide viewing angle, high luminance white LED backlit LCD • Large PV display (with character height of 18.1 mm which is the highest in the market) • Easy-to-distinguish parameter display with screen numbers • Easy-to-identify 11 segment alphanumeric display • Digit select key for easier value-setting (5 keys) 4. Most compact design in the market • Approx. 30% reduction in size compared to conventional models. (58 mm depth behind panel) 5. A variety of functions extending the possibility of temperature controller • 64 steps ramp/soak function • 8 PID setting pallets, 8 SV pallets, zone PID facilitate frequent change of control conditions • Loader interface provided as standard (Power can be supplied via loader cable. Loader software is available from our web site) • RS485 communication (optional) capable of cooperative operation, programless communication 1.
