6.2.1. Power supply connection
TCG120
is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for use in the
conditions of overvoltage category II. The power supply equipment shall be resistant to short circuit and
overload in secondary circuit.
When in use, do not position the equipment so that it is difficult to disconnect the device from the
power supply.
6.2.2. Digital inputs connection
Attention! Digital inputs are NOT galvanic isolated.
The
TCG120
digital inputs can be used in two modes – “dry contact” and “logic level”. The mode is
determined by the jumper, close to the corresponding input. To change the operation mode, the plastic
enclosure must be opened. Closed jumper determines “dry contact” mode while open “logic level”. By
default digital inputs are in “dry contact” mode.
In “dry contact” mode digital inputs can be used to monitor the state of a discrete device – door
contact switch, push button, PIR detector etc.
Following picture illustrates how a dry contact switch can be connected to the input (or inputs) of
TCG120
. One side of the contact is connected to “Digital In” and the other side is connected to “GND”
terminals.
6.2.3. Analog inputs connection
Attention! Analog inputs are NOT galvanic isolated.
Analog inputs of
TCG120
can be used for monitoring of DC voltage up to 60VDC. They can be
connected directly to batteries, solar panels, power supplies etc.
Built in functionality “Multiplier”, “Offset” and “Dimension” for every analog input gives possibility
to monitor sensors with analog outputs and see directly measured parameter. It is also possible to
monitor voltages bigger than 60 VDC with external resistive dividers.
Following picture illustrates how a battery can be connected to the analog input of
TCG120
. One
side of the contact is connected to “Analog In” and the other side is connected to “GND” terminals.
