RM-408
Ethernet thermometer & hygrometer with 8 remote RS-485 sensors and IO
RM-408 is an extended version of TH-355 with added RS-485 interface, to which up to 8 external temperature and humidity sensors RHS-1 can be connected. The device has also 1 local sensor and allows individual configuration of each connected sensor, data logging for ~210,000 records of all 9 sensors (1 local and 8 remote) and real time monitoring of all connected sensors. If a sensor reports out-of-range values, the device can send email messages, push notifications to Android devices, SNMP traps, HTTP request to predefined host or can activate its output relay.
The device has also two digital inputs, capable to work with "dry" or "wet" contacts and one SPDT relay output. The inputs are galvanically isolated and can be used to connect various external sensors, like magnetic door sensor, fire or smoke sensor, water leak sensor, etc. The output relay can be connected as sensor to your alarm or fire system, or to connect sirens, lamps or other suitable devices to it, which provides additional method for events signalling. All monitored sensors and the inputs can activate the relay. If needed, the device can be used even as a two-positional regulator, but should not be used for critical applications, as that's not its primary function.
