The time range is set via a control input (screw terminal 5).
Screw terminal 6:
Common GND connection for all inputs
Screw terminal 7:
(–) external power supply for the backlight option
Screw terminal 8:
(+) external power supply for the backlight option
(24 V DC ±20 %, 50 mA), Fuse 0.08A, delayed action
All smal tension, SELV, reinforced/double
insulation.
Signal inputs must be protected with an exter-
nal delayed 0.01 A fuse when the source
does not provide protective impedance
(fuse/current limitation).
