Installation
Î
Observe the permissible load of the relay specified in the technical data. A contactor
must be installed in the circuit for higher loads.
M-Bus interface (meter bus)
Up to three heat, water, gas or electricity meters with an M-Bus interface can be connected at
terminals 11 and 12 (M-Bus). The meter data (meter readings, momentary capacity, flow
rate etc.) are available over Modbus TCP.
Analog input
1)
The analog input at the terminals 9 (AI1) and 10 of the device is used for direct connection
of 0 to 10 V sensors or Pt1000 sensors. Select the analog input type in the SAM Gateway
Configurator tool (see the 'Start-up' section).
−
0 to 10 V
If a (positive) DC voltage between 0 and 10 V is applied to terminal AI1 to act in the
opposite direction to the COM terminal, the measured value can be read remotely using
the SAM HOME Gateway. It is used to read a signal of another device or a 0 to 10 V
sensor.
− Pt1000
If a Pt1000 sensor is connected to AI1 and COM terminals, the SAM HOME Gateway is
able to read the temperature at the sensor and make this value available for data remote
polling.
Digital inputs 1)
Both inputs DI1 (terminal 5) and DI2 (terminal 7) can be used to register the state of two
floating contacts (e.g. switches or relays of another device). A voltage input is not permitted.
Analog output
1)
The analog output at the terminals 13 (AO1) and 10 (COM) of the device is used for direct
connection of control inputs for 0 to 10 V signals or a PWM signal. It can be used for the
remote control of actuators or pumps.
Network connection (LAN)
The LAN port of the SAM HOME Gateway allows connection to a network. It can be
connected using an 8-pole patch cable to a network switch, hub or Internet router. It is also
possible to directly connect a computer.
The interface is also used for onsite configuration using the SAM Gateway Configurator tool
(see the 'Start-up' section).
