As of outer actuator device can be used: electric-actuated valve of solenoid type, magnetic starter, solid-state relay, triac. Management regimes: heating or cooling for two-position law of regulation; heating for proportional to, is proportional to - integral, is proportional to - integral - differential. The digital indication, the keyboard interface, the non-volatile memory of settings, the high accuracy of temperature control, two level access to programming controlled by the parameter system, sound and the light alarm, the programmed the selection of the type and sensitivity of transducer, the presence programmable current transmitter 4-20 provides for the microampere. Has 32 modifications depending on type of executive element, presence of current transmitter 4-20 microampere, voltage of supply and sensor model. Communication line: 2 (3) - chi wire in case of resistance of every wire 0 , 1 (5) ohm - not more than 2 (300) metal. Supply voltage - 220 in or 12 in frequency 50 (60) Hz. Nominal load impedance of current transmitter - 500 ohms. Outer supply voltage of current transmitter - 24 in. Switching current - 10; 0, 05; 1 and (depending on type of executive element of regulating channel). Assembly type - shield. The sensors are supplied on individual order. |
