Price of Johnson Controls tc-8903-1152-wk proportional integral thermostat detailed parameters of Johnson Controls tc-8903-1152-wk proportional integral thermostat and alternative Johnson Controls tc-8903-1152-wk proportional integral thermostat tc-8903-1152-wk is close to production stop. Here in Shenzhen, he Gong will introduce the detailed parameters of tc-8903-1152-wk and the alternative plan after the shutdown. There is also the introduction of tc-8903 series proportional integral temperature controller. Welcome to point out and purchase tc-8900 series analog controller, which is suitable for temperature control of two pipe, two pipe refrigeration / heat conversion, two pipe with electric heating coil or four pipe fan coil unit. Also suitable for humidity control The models of this series include all in one controller (tc8900), remote setting mode (es-8903) and built-in controller (tc-8903) Tc-8900 series electronic temperature controller is used in central air conditioning, heating and cooling system. When TSC series temperature sensor detects the change of load in the controlled environment, the temperature controller generates an increasing output signal with the control algorithm of proportional plus integral to adjust the reversible motor driver. Tc-8900 is easy to use and integrates the control of most common indoor air conditioners Features of Johnson auto control proportional integral control tc-8900 series temperature controller: integrated structure: sensor, positive and negative input, window input, proportional integral PI control, output control of measuring valve, mode sub comfort and standby button, and internal or remote variable resistance temperature sensitive element (NTC thermistor) of set point re adjustment potentiometer A transparent and lockable dial cover is used to prevent unauthorized personnel from improving the setting value Output function can be converted: forward or reverse (summer / winter) & mdash; & mdash; through local internal jumper or remote centralized switch (or touch shop with SPST as required), the proportion band can be adjusted Flexible installation: wall mounted, flush mounted, flush mounted or concealed mounted in fan coil unit, end device, etc Johnson auto control proportional integral control tc-8900 series temperature controller product specification: Product Name: tc-8000 electronic controller, incremental output action: proportional plus integral, positive or negative supply voltage: 24V, A.C + 15% / - 10%, 50 / 60Hz output signal: 24V, A.C (0.5A), power consumption through three terminal bidirectional thyristor element Bsp; & nbsp; & nbsp; & nbsp; 2Va (0.8A) no load proportional band & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; can be adjusted from 1-4k%. The factory sets the reset time at about 4K / 20% & nbsp; & nbsp; & nbsp; 5 or 2.5 minutes. Adjust the set value with an internal spanner to adjust 0-10vdc corresponding to - 8K, - + 8K (independent input, 15K ohm higher) standby set value 2K. By closing the external characteristics The range of setting value is shown in table sensitive element NTC thermistor wiring / suitable for 1.5mm thick wire shell Heavy 120g accessories (ordered separately) TSC series remote temperature sensor receiver in addition to Johnson proportional integral temperature controller tc-8903-1152-wk general user floating point switch proportional integral control, if you need a 0-10V control proportional integral set, you can choose tc-8901-2132-wk, with the same sensor ts-9104-8220 (discontinued, upgraded model ts3640d) about future tc-8903 series shutdown To solve the problem of product substitution, please give a brief description here, because tc-8903-1152-wk is connected to external sensor, and it has switch type. If you change the liquid crystal t6634-te22 proportional integral thermostat, it can also be used, but you need to accept the internal sensor. That is to say, t6634-te22 is a built-in sensor and cannot be connected with an external sensor. If you have to connect the external sensor, you can only use tc-8903-1152-wk, or tc-8903-1131, but they are a series, and all of them will stop production if they stop production. If the proportional integral control valve is newly installed, the new model must be selected. The price is cheap, and it's liquid crystal. In this respect, he union of Shenzhen recommends it Johnson Controls Johnson Controls Johnson Controls HVAC equipment in Greater China stock spot supply: Johnson room type mechanical thermostat t2000eac- OCO, t2000aac-oco, t125aac-jso, t125bac- JSO, t125fac- JSO, t125fac- JSO, Johnson Controls room type liquid crystal thermostat t5200-tc-9jso, t5200-tb-9jso, t5200-tf-9jso, t6634-ta10-9jso, t6634-te20-9jso, t6634-te21-9jso, t6634-te22-9jso, t5200-tb-9j20-9jso, t6634-te21-9jso, t6634-te22-9jso, t5200-tb-9jso, t5200-tb-9j200-tb-9jso, t5ro, t6334-tb20-9jso T7200-tb20-9joo, t7200-tb20-9job, temperature controller with touch screen t8200-tb20-9js0, t8200-tf20-9js0, t8200-tb20-9jf0.
