Dynamic resetting behaviour
Screw terminal 6:
Common GND connection for screw terminal 4 (reset
key locking input) and screw terminal 5 (reset input).
Screw terminal 7:
(–) external power supply for the backlight option
Screw terminal 8:
(+) external power supply for the backlight option
(24 V ±20%, 50 mA), Fuse T0.08 A, delayed action
All low voltages, SELV, reinforced/double
insulation.
Signal inputs must be protected with an exter-
nal delayed T0.01 A fuse when the source
does not provide protective impedance (fuse/
current limitation).
