6.4. B3D Connection with Access Control Systems
6.4.1. Connecting with an actuator mechanism
The B3D controller can control the actuator mechanism of an ACS (turnstile, gate, barrier, etc.) via a dry
contact signal. For this normally open (NO) or normally closed (NC) contacts of Relay 1 of the Connector
#1 are used. Parameters of relay:
Maximum switching voltage DC: 48 V
Maximum swi
tching current DC: 7 А
Maximum switching voltage AC: 250 V
Maximum switching current AC: 10 А
If the actuator device requires a larger current or voltage, then an external relay must be used.
6.4.2. Connecting an external reader
An external reader connects to the B3D controller via Wiegand Interface. The maximum length of cable
is 150 m. The cable used must contain several shielded twisted pairs 24 AWG. Conductors for Data0 and
Data1 lines must be not twisted.
FIG 62. Connection of an external reader
The B3D Controller pr12 V power to the external reader. The maximum current of power is 300
mA.
If necessary, an external reader can be powered from a separate power source. In that case, grounding
of the power sources should be united (FIG 63).
