Product Description:
The system is composed by:
- W200 weight indicator.
- ATEX certified Zener barriers (dimensions: 105×12.6×82 mm, standard OMEGA/DIN rail mounting):
- MTL 7766Pac supply barrier
- MTL 7761ac signal barrier
- ADPE explosion proof box (ATEX/IECEx) equipped with heat-resistant transparent tempered glass window and 5 external buttons which performs the same function as W200 keypad:
