Leuze electronic DDLS 200 series bus type infrared optical data transmission equipment

Product positioning and purpose

DDLS 200 is an infrared optical data transmission system from Leuze Electronics, supporting INTERBUS 500 kBit/s and RS 422 bus for stable data transmission under unobstructed line of sight.

Applicable scenarios: Automated stereoscopic warehouses, fixed transmission between buildings, rotary transmission, long-distance data transmission of stationary/moving objects.

Laser safety: Class 1 (EN 60825-1), prohibits direct viewing of the beam at close range.

Electrical interfaces and functions

terminal definition

Vin: 18-30 V DC positive pole

GND: 0V negative pole

PE: Protective Grounding

IN: Remote start stop input (0-2 V=off; 18-30 V=on)

OUTTWARN: Receive strength alarm output (maximum 100 mA, short circuit/surge/overheat protection)

Switch S1

On: Ignoring IN input, the device is running frequently

Off: Enable IN input control for start stop

Operation and Display

indicator light

PWR/UL: Power and self-test status

AUT/MAN/DJ: working mode indication

LED light column: 10 segments of received signal strength

working mode

AUT (automatic): Normal operation, displaying the local reception strength

MAN (manual): Debugging mode, threshold increase

ADJ (Alignment): Transmission interruption, displaying the receiving strength of the other end

Mode Switch

Long press>2 seconds: AUT ↔ MAN

Short press: MAN ↔ ADJ (both ends must be MAN)

Installation and alignment requirements

install

Paired installation in opposite directions, unobstructed light path

Fix with 4 Φ 5mm screws

align

Optical opening angle: ± 0.5 °

Fine tuning angle: ± 6 °

Anti interference spacing

Parallel frequency: 120 type ≥ 300 mm; 200 type ≥ 500 mm

Parallel on the same frequency: the minimum spacing needs to be calculated according to the distance formula

Debugging, operation, and maintenance

Power on: Automatic self-test, entering AUT mode normally

Alarm: Signal strength too low → OUTVNet activated

Maintenance: Clean the optical windows monthly using a soft cloth and glass cleaner, and avoid solvents such as acetone

Interruption impact: Power outage/obstruction of the optical path is equivalent to bus disconnection

Key questions and answers

How to control the remote start stop of DDLS 200, and what is the function of S1 switch? Answer: Start stop can be achieved through the IN terminal: 0-2 V DC to turn off transmission and reception, 18-30 V DC to work normally; When S1=On, ignore IN input and keep the device running. When S1=Off, enable IN remote control.

What are the differences and switching rules among the three working modes of DDLS 200? Answer: AUT operates automatically and normally; MAN is for manual debugging; ADJ stands for optical path alignment (transmission interruption). Switching rule: Long press>2 seconds to switch between AUT and MAN; Short press to switch between MAN and ADJ, not directly AUT ↔ ADJ。

What are the core requirements for DDLS 200 installation alignment and anti-interference? Answer: The optical path must be unobstructed, with an optical opening angle of * * ± 0.5 ° and a fine adjustment of ± 6 °; The minimum spacing between parallel frequencies is 300/500 mm * *, and for the same frequency, the spacing should be increased according to the formula; Paired installation ensures coaxial optical paths.
