Description:

The units of the signal converter series SU4 have been developed for level converting. There are three
channels at disposal 5V (TTL) or 24V (HTL) are converted into RS422 impulses. The units are potential
isolated between input and output. The switch conditions are indicated by LED’s in each output.

Application:
Signal conversion 5VDC (TTL) / 24VDC (HTL) into RS422

Note on safety:

Disconnect the power supply before attempting to open the unit.

During the operation of this module it is possible that parts of the module, even there is extra-low voltage, (for example shunt measurement) are under dangerous voltage! Therefore a non-observance of this caution may cause damage of property or physical injury.

Only trained qualified personnel should install or operate the unit. Before installation the qualified personnel should read the documentation and should familiarize themselves with the unit.

If there is visible damage to the body of the unit it should be immediately replaced and not put into operation.

Please ensure that there is a sufficient prevention against electrostatic discharge during installation of the unit.

Installation Information:

Pay attention and make sure the unit is far away from mounted sources that may disturb the device such as magnetic coils, transformers, frequency converters etc.

Wiring advise:

Use only shielded cables. The shield is to be connected extensively to ground. Do not mix power- and signal-wires/cables in the same cable tray.

Limited warranty:

The LEG Industrie-Elektronik GmbH warranted that the product does not have any material or processing defects in a period of 5 years after date of delivery.

It is up to the choice of LEG to repair or to exchange an inoperative unit.

Subsequent damages or any claim for indemnification above the functionality of the unit are excluded. This limited warranty is only valid if …

  1. the product was installed and put into operation according to the LEG operation documentation;
  2. the technical configuration of the power supply was abided;
  3. the product was not used for unintended purposes;
  4. there were no unauthorized modifications or manipulations, misuse or repairs without previous agreement from LEG .
