Dual outputs, displays and sensitivity correction functions

Dual output

Features 2 control outputs as standard. For each output channel, you can set Light ON/Dark ON, timer and threshold independently. Also, a dual output type with a control output and analog output (4 to 20 mA) is available. (Analog output type is stand-alone type only)

0 to 9999 dual digital display (0 to 4000 when in Fast response time mode and in the case of analog output equipped types)

  • Current receiving light quantity and threshold are shown using dual displays. Fine sensitivity adjustments can easily be made after teaching. Also, through the adoption of a high brightness LED, numerical values can be confirmed at a glance even in bright worksites.

  •  Dual sensitivity correction function “ASC” (Automatic sensitivity correction/restoration)
    *When using transparent object teaching

    This function works to maintain optimal sensitivity levels over long periods of time by automatically performing sensitivity corrections when light level decreases occur due to contamination of fiber tips caused by dust, etc. Because threshold levels will be automatically restored after cleaning, re-teaching is not necessary. (ASC can be switched ON/OFF)

  • Dual support for difficult detection conditions

    Automatic power control “APC” + 4 element red LED light source The D2RF employs a newly developed 4 element red LED for the light source. In addition to minimizing the decreases in emitted light that occur over time, the “APC” (Automatic Power Control) automatically corrects changes in light emission levels. This function is effective when a change to the emitted light power occurs, causing instability and difficulty in performing detection. (APC can be switched ON/OFF)

Interconnection

  • Up to 8 units can be connected

    Wiring can be reduced

    Up to 8 inter-connection type master and slave units can be linked. (cross talk prevention functionality for up to 4 units) Because only output line wiring is necessary for slave units, necessary man-hours for wiring can be cut in half.

  • Batch setting for amplifier settings

    Batch setting is possible

    This function enables simultaneous setting of all linked (expanded) amplifiers. Zero reset and 1-point teaching, as well as copying of amplifier settings from upstream (master unit side) to downstream (terminal slave unit side) can be performed. Because separately sold setting tools are not required, convenience is maximized.

Cross talk prevention

Installing fiber cables side by side (only for Long mode and Standard mode)

  • By linking the master and slave units, light emission timing can be shifted electronically to prevent malfunctions caused by cross talk. (Up to 4 amplifiers)

User-friendly

External teaching is available

Teach input

  • By setting CH2 of the control output as the teach input, adjustments to the optimal sensitivity for multiple sensors can be made simultaneously with one teaching. This is very useful for amplifier units installed in narrow space.

    *Analog output equipped types do not have a teach input.
    *Teaching mode will be the mode performed in advance on the amplifier main unit (default: 1-point teaching)
