2.3 Powering the module
For powering Pager 7 module 9-
30V DC is required. The module’s nominal current consumption
is 120mA, however, it may occasionally increase to several times (up to 500mA at 12V DC).
The incorrect power supply may cause the module to malfunction!
If the proper power supply cannot be assured otherwise, auxiliary power supply (230V AC/12V
DC; 1A) can be ordered from the manufacturer.
2.4 Wiring
2.4.1 Wiring of Pager 7 Z4
System terminal inputs and outputs:
V+:
Supply voltage 9-30V DC (min. 500 mA)
V-:
Supply voltage negative polarity
IN1:
1. contact input
IN2:
2. contact input
IN3:
3. contact input
IN4:
4. contact input
OUT1:
1. normally open relay contact
OUT2:
2. normally open relay contact
In our example IN1 and IN2 inputs are normally
open (NO), while IN3 and IN4 are normally closed
(NC) inputs.
