RS485/232 Serial Interface
The interface is intended for communication with external devices via the RS485/232 bus. This
interface can be either RS485 or RS232, depending on the equipment ordering option.
1-WIRE Interface
Standard digital 1-WIRE interface is designed for communication with external devices (such as
temperature sensors, i-Button, etc.)
Power Supply for Ext. sensors
This output is intended for supplying external sensors. The power supply is controlled by the
Industrial Sensor.
The output has built-in overcurrent protection. The output voltage is equal to the voltage of the
external power supply.
Note: In the modification of the Industrial Sensor without a built-in DC/DC converter, an option to
power external sensors from an internal battery is possible (the option is ordered separately). In this
case, the output voltage is equal to the battery voltage.
Outputs
The output block contains two digital outputs. When the output is activated, the signal is shorted to
ground. In the passive state, the lines are open. Maximum current 2A.
Battery
The device has a built-in Li-SOCl2 Size C battery. The battery is powered when there is no external
power supply. When operating on battery power, the device enters a low power mode (see
Application description).
Note: Do not disconnect the internal battery unnecessarily for a long time. This can lead to a reset
of the RTC clock.
DC/DC Power Convertor (optional)
The built-in DC/DC Converter ensures the operation of the device from an external power source.
Permissible range of external supply voltage 5-55V
The DC/DC Converter may be absent depending on ordering options.
Battery Connector
The connector is only for connecting a 3.6V battery.
Caution: keep the voltage polarity indicated near the connector.
Sealed cable gland
Sealed connector for wires to external sensors.
Power Cable for Communication Board
This cable powers the Communication Board.
Flexible Cable
This cable connects two boards: Communication and Extension Board
