Screw terminal 5:
Operating mode switch (Mode)
Contact input / Open Collector NPN
(switching at 0 V DC)
Low level: 0…0.7 V DC
High level: 3…5 V DC
Input resistance: approximately 2.2 MOhm
Function: see Table 2
Screw terminal 6:
GND connection common for all inputs
Screw terminal 7:
(–) external power supply for the LCD backlight option
Screw terminal 8:
(+) external power supply for the LCD backlight option
(24 V DC ±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).
