supply
* Contact positions are shown in
powerless state
4.1 Power supply
The unit accepts DC power supply from 17 V to 30 V when using terminals 1
and 2 and the consumption depends on the level of the supply voltage (typically
between 80 mA and 150 mA plus current taken from auxiliary output).
In specific models, for AC supply, terminals 0 Vac, 115 Vac or 230 Vac can be
used. The total AC power consumption is 7.5 VA.
Units with option LD30x-P4-... are designed for either 24 Vac or 42 Vac power
supply and the screw terminals are marked correspondingly.
LD305 has -P4- option only, i.e. 17Vdc 30Vdc power supply.
The pictures in the previous page show a dotted line for grounding to PE. This
connection is not necessary, neither for safety nor for EMC. However, with
specific applications, it can be useful to ground the common potential of all
signal lines.
NOTE
When using this earthing option, please note that:
1. all terminals and potentials marked “GND“ will be earthed;
2. you should avoid multiple earthing, e.g. when you use a DC power
supply where the Minus is already connected to earth etc. Especially
under poor earthing and grounding conditions, multiple earth
connections may cause serious EMC problems.
4.2 Aux. voltage output
Terminal 7 provides a 24 Vdc / 120 mA max. auxiliary output for supply of
sensors and encoders. Units with TTL inputs (option -M8-) provide a 5 Vdc / 120
mA auxiliary output on terminal 7 instead.

4.3 Inputs A, B and Reset
In the basic set-up menu (see the “7.1 Basic settings” section on page 24) these
inputs can be configured to PNP (switch to +) or to NPN (switch to -). This
configuration is valid for all three inputs at a time.
The factory setting is always PNP.
With standard units the input level is always HTL (Low < 2.0 V and High > 9.0 V).
Units equipped with option -M8- provide TTL / CMOS) level (Low <0.8 V and
High >3.5 V).
NOTE
1. Independently of your setting, all functions of the unit are “active HIGH“
and the unit triggers to positive transitions (rising edge).
2. With NPN setting please be aware that an open or unused RESET input
is HIGH. Therefore the unit will be kept in a continuous RESET state and
will not work, unless you tie the Reset line to GND (terminal 1 or 6).
3. When you use 2-wire NAMUR type sensors, please select NPN, connect
the negative wire of the sensor to GND and the positive wire to the
corresponding input.
Typical input circuit (standard version with HTL inputs):
PNP
4,7k
GND GND
+24V int.
Input

GND
Input
+24V int.
NPN
The counting inputs A and B are designed for input frequencies up to 100 kHz
(with all counter modes) and up to 25 kHz (with all other operating modes).
The minimum pulse duration on the Reset input must be 500 µsec. (maximum
frequency 1 kHz)
All inputs are designed to receive impulses from an electronic impulse source.
Should you exceptionally need to use mechanical contacts, please connect an
external capacitor between GND (-) and the corresponding input (+). With a
capacity of 10 µF, the maximum input frequency will reduce to 20 Hz and
