Z-LINK1-LO is a 869 MHz radio device designed for remote communication operating in a transparent way with ModBUS RTU protocol and exploiting the physical layer of LoRa (Long Range) transmission technology. Based on a UHF radio modem, Z-LINK1-LO enables communication between SENECA Z-PC Line I/O modules and generic ModBUS devices. Z-LINK1-LO stands for make easier cabling of power and serial bus communication mounted in IEC 60715 DIN rail. The module is easily configured throgh DIP-switches or PC software EASY SETUP. It also includes 2 serial ports (1 RS232, 1 RS485) and an isolation stage between communication and power up to 1.500 V. Compliant with ETSI standards and AES128 data encryption, Z-LINK1-LO can operate in remote I/O or bridge operating modes with point-to-point and point-to-multipoint communication mode. LoRa technology allows the radio modem to achieve high coverage (up to 1 km with external antenna), 40 mW transmission power, highest noise immunity and sensitivity. ANT-LINK1-MG antenna is not a mandatory accessory but is strongly recommended for better signal quality.
