7.4.3 SLC technology - B24C
Fig. 26: B24C module
1 2-wire cable for supply voltage and signal
2 (THC-E, by others)
X2 Socket for an actuator
X3 Sockets for limit switches
6 / 7 2-wire cable to THC-E control module for signals
and supply voltage, 2 x 1.5 mm², 150 m max.,
interchangeable cores
11 Not to be used
12 GND
13 24…27 V DC (30 mA max.)
14 IN
Terminals 12, 13 and 14 – duct smoke detector:
 If you want to connect a duct smoke detector,
remove wire link X between terminals 13 and 14.
 You may use terminals 13 and 14 to connect a duct
smoke detector or any other volt-free control con-
tact, e.g. a fire alarm system. When the contact
opens, the damper blades move to the defined safe
position. For this case the terminals 13 and 14 of
several BC24 modules can be switched in parallel.
The actuator and the control module are factory wired.

1 EK-JZ with integral control module B24C
2 THC-E (switch cabinet)
3 Fire alarm system and central BMS (if any)
Advantages

Control of one damper or many dampers simultane-
ously (in parallel)
Disadvantages

Wiring is comparatively time consuming
