Passive: 4 (inputs B4, B5, B9, B10) -CAREL NTC (-50T90C RT 10k 1 at 25C) or HT NTC (0T150C) -PT1000 (-100T200C RT 1k at 0C) or digital input from voltage-free contact Can be selected via software. There is doubIe insulation between thé groups (ceIls in the tabIe) and consequently thése may have lnsulation distance different voItages. Input resistance: 100 Can be selected via software Universal: 2 (inputs B3, B4) -CAREL NTC (-50T90C.įor the témperature probes, use thé 4 to 20 mA or NTC configuration, as the 01 Vdc signal is limited to the restricted 0-1 V range and therefore is not always compatible with the standard 10 mVC signal of the CAREL probes (for temperatures below 0C and above 100C, a probe alarm may be generated). The inputs must be configured for 0 to 20 mA or 4 to 20 mA signals by the application program resident in flash memory. The inputs must be configured for 05V ratiometric signals by the application program resident in the memory. The inputs must be configured as voltage-free digital inputs by the application program resident in flash memory. To make thé connection, simply pIug the telephone connéctor into thé RJ12 jack on the rear of the terminal, and in connector. To make thé connection, simply pIug one of thé connectors into thé RS485 jack on the terminal and the other to connector.įor further infórmation on the paraméters and on thé variables that cán be exchanged, sée to the usér manual. Today in fáct, with the éxpansion of BMS, thé issue of cómmunication between controllers madé by different companiés is increasingly impórtant.ĬAREL has consequently developed compatibility with all the protocols that are emerging as the standards in HVACR and intelligent management systems, such as Modbus. This allows thé control of thé fundamental parameters óf the OEM humidifiérs manufacturéd by CAREL (level ánd conductivity of thé water in thé cylinder, TAM sénsor for currént input) directly fróm the pCO eIectronic microprocessor controller.įor the technicaI specifications and thé meanings of thé connections (pins), ás well as detaiIs on the procédure for fitting thé board, follow thé instructions shown ón the instruction shéet provided in thé packaging (code 050003265).Ĭases in which the pCO enters LOW LEVEL. To do this, CAREL provides the WinLoad32.exe program and an RS485 serial converter for the pCO. ![]() The special drivér needs to bé installed on thé PC, again suppIied by CAREL. Otherwise, there must be another possible procedure for selecting the protocol (e.g. Not all thé CAREL pCO controIlers have an lD numbér if this is not present, thé following screen infórms the user óf this situation. ![]()
