HANNA HI 504903-1 GSM Supervisor for HI 142 (wavecom - USA), HI504903
HI 504903 is an intelligent interface between up to 31 HI 142 temperature dataloggers connected through an RS485 port and a GSM cellular phone or a local or remote computer with the HI 92140 HANNA instruments software. HI 504903 can acquire from each HI 142 information about active alarms, errors, current status and real time temperature values.
HI 504903 is also provided with one digital input (typically an alarm relay) from "non-intelligent" instruments with only an alarm relay contact or another digital output signal.
Moreover, the interface features one digital output and an input for enabling/disabling the SMS sending function.
LED's indicate error conditions, active alarms, signal coverage for the cellular module, digital output and cellular module status.
HI 504903 can be completely configured through the HI 504903SW software provided with the instrument. Other important characteristics of the interface are the real time clock, self-diagnostic capabilities and internal backup battery which provides a power supply and causes an alarm SMS sending in case of mains power failure.
