Dry Direct-reading meter (module) [] M-BUS ultra-low power wide voltage DC16-42V, voltage stability, quiescent current <0.3mA. [Online upgrade] can be implemented in application upgrade (IAP) program to update the meter. [Mass Storage] large program space (64K Flash), 4K of memory (RAM), 4K data storage (dataflsh). [Protocol] support DL / T-97 \ 2007, CJ / T188-2004, MODBUS, "private custom" and a variety of communication protocols. [Passive Direct Reading - Reading] no meter reading is not real-time power, want to copy to copy, greatly reduce the failure rate and increase the service life. Sensing - based table - Separation] photoelectric sensor portion in contact with the base table counter means to zero, does not affect the original measurement accuracy, completely solve the direct-reading meter measurement accuracy problems. [Zero errors] unique coding technology, instant power meter reads the counter status word round, the decoded data is completely consistent with the base table data, thereby achieving zero error. [Simple construction] Each meter has its own unique address code, two-wire polarity, easy on-site construction management and maintenance [patents] character wheel has its own patent, patent number: ZL2015200247856 [electromagnetic compatibility] from external magnetic fields and reflux influence, usually electronic part is no electricity, no work state, will not be subject to any environmental interference or lightning effects, MBUS interface circuit super anti-jamming capability, EMC testing to meet national standards. [Communication speed] 1200bps, 2400bps, 4800bps, 9600bps and other adaptive rate. [Valve] with valve operation control function. Be flexible and user-friendly on-off valve MCU resource allocation: High-speed clock 1-32Mhz, 1% accuracy (-20 ~ + 85 ℃) within brand Renesas models R5F100BEANA chip program space 64K (byte) RAM size of 4K (byte) data Space 4K (byte) Uart 3 CH (supporting data length 7,8,9 bits) AD 8 CH IAP support PIN pin 32 IO drive capacity> 40mA multiplication and division on its own hardware multiplier and divider QFN32 package Tang Electronics Renesas outstanding partner support great original, complete model, perennial spot.
