| Description: | S shape dimension: SR91 (48 x 48mm) SR92 (72) SR93 72mm x x (96 96mm) SR94 (96 48mm)... S SR90 series is Japanese island electricity company in 2002 the latest technology of the product, it highly SR60 to SR70 series summarized application experience more outstanding performance and high reliability design thought. Have free input, show precision of 0.3 level, manual function, adjust output limiting, double setting, double adjustment output, simulation 20ma output, digital communication function, the front panel accord with IP66 level protection standards. Using the island of electricity without overshoot expert PID algorithm, two groups of independent PID parameters, perfect function and performance to price than island SR73A/electrical SR74A series. S for operator more striking is high brightness big character display, precision is + - 0.3% FS + 1 word, sampling/show cycles per second 4 times. S system before using, and can start auto-tuning function, find the PID parameters on the system, which can simplify debugging, improve the scene of the control quality. S expert PID algorithm included SF overshoot inhibit coefficient, reasonable option, which can effectively avoid system overshoot or owe tone. S for 0-100 seconds of power, slow starting in a certain extent, reduce load the surge current, protection devices and prolong the service life of heating elements. S output amplitude limit can be used to limit the size of the valve opening, avoid excessive heating power design for special heating element and a warming period of power restriction, etc. S second output functions (option), can be used for heating/cooling regulating or b&t heating control. Still can adjust double adjustment interactions between the interval of dead zone DB, achieve already improve control accuracy, and save energy purposes. S greenhouse day control, heating system is preheated or insulation USES need double set SB (option), with a contact can be realized double setting options. S for prevent from technical requirements of set limits, available setting limiting function to avoid mistake. S two separate events relays may be conducted nine kinds of events, including: the upper and lower limit absolute deviation of the upper and lower limit, the deviation of the internal/external alarm way. S isolation digital communication interface (option), optional RS232C, RS485 interface, mouth address 1 ~ 255. Still can provide seaman''s light isolation intelligent RS232/485 communication converter, cooperate XF - 2000 Chinese Windows configuration software, and the upper aircrew becomes small distributed system. S simulation 20ma (option) : measured values, setting, deviation, adjust 20ma output, for field records data, many area control temperature or cascade adjustment. S single-phase heater disconnection and heating loop alarm (option) : current monitoring scope: 0.0 ~ 30.0 A and 0.0 ~ 50.0 A. S sensor via the calibrated linear error or for placement measuring error caused by the positive and negative offset, can be installed as measured values PV show compensation. S for avoid site measurement disturbance, can install anti-interference digital filtering time constant. | |
