Building on the success of the Sensaphone Sentinel and Sentinel Cellular cloud based devices the Sentinel Pro has now been developed. There has long been a need for a wireless (3G etc.) modbus gateway. The system monitors, delivers alarms, and datalogs input/output points from third-party Modbus sensors, transducers and programmable logic controllers. The system supports Modbus RTU/485 and Modbus TCP.
Key differences between the Sentinel and Sentinel PRO models:
|# of inputs
||12 Digital or Analog also 64 Modbus Registers
||Contact, 2.8K, 10K, 4-20mA
||Contact, 2.8K, 10K, 4-20mA, Modbus
||One low voltage NO/NC relay output – Manual or automatic alarm switching
||Two low voltage NO/NC relay output – Manual or automatic alarm switching
Both alarms are available in Ethernet and cellular (3g) versions.
