8 Transponders and loop elements
All elements described in this document may only be used in dry rooms. This means also
cable ducts and false floors.
8.1 General
Standard inputs and outputs are provided in the basic configuration of SIGMASYS C and M
control and indicating panels for external displays (FBF, KD, external alarm). In addition, eight
free outputs are available on each module when using GMG-S and PMG-S modules.
The detection of signals via floating contacts (technical messages) or the execution of moni-
tored and non-monitored control facilities are generally performed via loop elements (e. g.
transponders). The cable network normally required for control facilities can thus be elimi-
nated.
Inputs and control facilities near the control and indicating panel can be implemented by addi-
tional components that are accommodated on the option slots of the SIGMASYS control and
indicating panel and the SIGMASYS empty housing.
The following relays can be used in the case of higher currents and voltages and for control-
ling lines with applied voltage:
Relay modules A5Q00001234 2 changeover contacts
Technical data
Control voltage 18 V … 30 V
Coil resistance 900 Ohm
Control current approx. 24 mA
Contact load
Two changeover contacts with maximum switching voltage 250 V AC, 220 V DC
Switched current in light-duty zone µA from 100 mA to 24 V
Minimum switched current 10 mA (with one charge over 100 mA)
Maximum switched current at 30 /110 / 220 V DC 8 A / 0.3 A / 0.12 A
Maximum breaking capacity 230 V AC 400 VA
Dimensions (H x W x D) in mm 84 x 16 x 70
Temperature range 0 … 60 °C
Installation on 35 mm top-hat rail
Table 19: Relay module - technical data
These relays are designed for installation on the 35 mm top-hat rails provided in the control
and indicating panels
The relay modules 9AR, 5AR and 5ARD cannot be used at transponders.
A transitory current limit must be set for appliances with a high transitory current such as elec-
tric light bulbs and flash lights. The maximum current of the relay in use must not be exceed.
8.2 Loop elements
8.2.1 Maxitransponder SPF 3500, 4STE control module
The function of the transponder is the same as that of the 4STE control module. The 4STE
control module consists of a transponder module and is intended for installation in
SIGMASYS control and indicating panels (1 option slot).
In SPF 3500, the transponder module is accommodated in an IP54 housing.
