TBS recommends to not operate the relay at the upper level of the voltage range for long periods of
time, and not to power devices constantly through the relay, as such may shorten its life span.
DISCLAIMER:
On-board relays must not be used to activate security access equipment such as gates or doors to
grant access to secure areas, as they can be accessed and bridged by an intruder. Only non-security
critical functionality such as lights may be directly activated using the internal switch.
Instead, use the data communication capabilities of the device (ethernet, serial interfaces) to
communicate to relays inside the secure area to activate security access equipment. For such, TBS
offers two dedicated controllers.
5.6 Connecting TBS Controllers
For various applications TBS Terminals need to be connected with external controllers, e.g. to open a
door. TBS offers two own solutions:
- TBS CONTROLLER SMART (4 relays, 4x GPIN, 4x GPOut, connected via RS-485 or LAN)
- TBS CONTROLLER LITE (RelayBoard with 2 relays, connected via RS-485)
5.7 Connecting Third Party Controllers
Connection to 3
rd
party controllers is very often done via Wiegand interface. TBS devices offer Wiegand
output lines supporting various standard formats (26 and 37bit).
Wiegand Connection
The TBS terminal provides Wiegand OUT connections that can be directly connected to the
corresponding 3rd party controllers Wiegand IN.
