Electrical parameters
1.
Telephone network
Terminals No. 7 and 8 in acc. with 9 and 10
Un = AC 90 V / f = 25 Hz
Um_AC = AC 100 V / f = 2
0 … 68 Hz
Um_DC = DC 66 V
Um = 120 Veff
AC and DC voltage parts can be superimposed.
Recommended conductor cross-sections are 0.2 to
4.0 mm² rigid or 0.2 to 2.5 mm² flexible.
2.
Potential-free relay contacts
Terminals No. 4/6
Umax = AC 250 V
Imax = 5 A
Pmax = 100 VA
In this case use recommended wire cross-section
of 1.5 mm² to 4 mm².
or
Umax = DC 230 V
Imax = 0,5 A
Pmax = 100 W
In this case use recommended wire cross-section
of 0.75 mm² to 4 mm².
or
Umax = DC 50 V
Imax = 1 A
In this case use recommended wire cross-section
of 0.75 mm² to 4 mm².
or
Umax = DC 30 V
Imax = 5 A
Pmax = 100 W
In this case use recommended wire cross-section
of 1.5 mm² to 4 mm².
The terminal no. 5 according to the connection
diagram is without function.
3.
The telephone network is securely and galvanically
isolated from the potential-free relay contacts.
The voltage may not exceed 250 Veff at an
individual relay contact.

3 circuit. U = AC 30 V… 100 V
≥ 8 kΩ (@ 30 V ... 100 V / 20 … 68 Hz)
Function of relay contact 1 (terminals 1 and 3) adjustable
by means of sliding switches:
DIP switch 4 = OFF
→
contact follows the call signal
DIP switch 4 = ON
→
contact closes for approx. 1.5 seconds
Function of relay contact 2 (terminals 4 and 6) adjustable
by means of sliding switches.
The contact always follows the call signal. After the call signal, i.e. in the call
break that follows, the contact remains closed for the duration according to
the following setting (call break bypass):

Note:
The smooth functioning in the case of a “double call”, i.e. two short call signals one behind the other, cannot be
guaranteed given the abundance of double ca
ll signals worldwide. It is the operator’s responsibility to test the
function on his system in these cases.
