The EM8000D00 extension module is a sophisticated solution for 80xx time reference systems housed in a DIN rail enclosure. This module features two demodulated IRIG-B signals via a fiber optic connector for multimode fiber optic cables, with a wavelength of 820 nm and an ST connector type. Additionally, it offers two 24V IRIG-B DCLS signals through pluggable screw terminals. The module dimensions are 130x135x105 mm (D x W x H) and is only available with the purchase of a new DIN rail time reference system, making it unsuitable for on-site expansion or exchange.
