Users in factory automation, chemical industry, pharmaceutical industry and telecommunications will profit by this addition to E-T-A’s product range of system solutions.
Up to now wiring of supply feed, auxiliary contacts, load outputs and various special functions had to be done individually and therefore was relatively time consuming. Now the new circuit board with integral terminal blocks offers fast and professional support with connection in control cabinets. The terminal blocks are soldered on to the circuit board from the front side, on the rear side the circuit board features integral terminals. Wiring of the rack becomes much more compact and may be carried out much faster. Risk of wiring errors is minimised.
An integral pull relief in the rack ensures resistance of the circuit board against mechanical strain under harsh everyday conditions. The usual moveable wiring and its subsequent problems are thus excluded.
The 19BGT circuit board has been designed for single pole or double pole circuit breakers with max. 30 poles. This allows wiring up to 30 channels single pole, up to 15 channels double pole or twice 15 channels single pole redundantly for use with two separate circuits. A number of E-T-A overcurrent protection products may be used in connection with this printed circuit board: electronic circuit breaker type ESS20, electronic circuit protector ESX10, thermal-magnetic circuit breaker types 2210, 3600 and 3900, or the solid state remote power controller E-1048-700. Max. supply current is four times 50A, max. 20A are possible per load output.
