Terminal 4-5: POWER SUPPLY UNIT - type PD / PX:
To power the unit an internal battery can be used (type PB) and / or an external DC power supply
of 8-30V DC (type PX) or 16-30V DC (type PD).
Connect the "
-
" to terminal 4 and the "
+
" to terminal 5. When power is applied to these terminals, the
optional internal battery will be disabled / enabled automatically to extend the battery life time.
The input loop powered model - type A-PL - does not have this power supply option.
Terminal 6: sensor supply voltage - type PD.
With this option, a sensor supply terminal comes available which offers the same voltage as
connected to terminal 5 (internally linked).
Remark: this terminal is only available if option PD has been ordered.
Terminal 7-8; control output – type OT:
With SETUP 3, the function of this output is set to a low and high control output.
A passive transistor output is available with this option. Max. driving capacity 300mA@50V DC.
Terminal 9-10: power supply backlight - type ZB (option):
To power the backlight, a voltage in the range 20-30V DC has to be connected.
Maximum current 30mA. Connect the "
-
" to terminal 9 and the "
+
" to terminal 10.
