A single RS485 reader interface can supply a maximum of 750 mA (12V) current. So, the entire current
consumption should be less than this maximum value when the readers share power with the panel. For
calculation, please use the maximum current of the reader, and starting current is usually more than twice
the standard work current.
Using the KR502M-RS card reader as an example, the standby current is less than 80mA; the maximum
current is less than 90mA. When starting the device, the instantaneous current can reach 180 mA. For an
RS485 reader, considered that the starting current is large, only four readers can connect to the power
supply through the RS485 reader interface. So, the power of the control panel can only connect up to 2
readers.
If RS485 reader is connected externally and shares the power supply with the device, it is recommended
that the connection between the RS485 reader port and the reader be no longer than 100m. Otherwise, it
is recommended to use a separate power supply for the reader.
For the devices which consume more power, we suggest using different power supplies to ensure
steady operation.
Relay Output Connection
3.7
C2-260/inBio2-260 has three relays (two used as control locks by default, and the other one used as
auxiliary outputs).
The relays for auxiliary outputs may connect to monitors, alarms, doorbells, etc. Auxiliary outputs are set
through the relevant access control software. Please refer to the respective software manual for details.
1.
The default connection mode of the door lock is “dry mode.” In general, the electronic lock uses an
external power supply separately. The wiring mode of the door lock relay cannot be changed, except
that the auxiliary output relay. The diagram below uses the example of a door lock connection to
demonstrate the output relay connection.
2.
An access control panel provides multiple electronic lock outputs. The COM and NO terminals apply
to the locks that are unlocked when power is connected and locked when power is disconnected.
The COM and NC terminals use the locks that are locked when power is connected and unlocked
when power is disconnected.
3.
Our access control panel is powered by standard PoE or access control power. You can choose either
one of the power supplies as needed. Both two power supplies provide 12V/3A power for only the
power consumption of the control panel, Wiegand readers, and output power consumption of RS485
reader.
4.
To protect the access control system against the self-induced electromotive force generated by an
electronic lock at the instant of switching off/on, it is necessary to connect a diode in parallel (please
use FR107 delivered with the system) with the electronic lock to release the self-induced
electromotive force during the onsite connection for application of the access control system.
