2km Wireless Modbus RTU I O Module Wireless ON OFF Control One Master To 8 Slaves
1. LS-R324 General Introduction
LS-R324 wireless DTU whose transmission distance reaches 3km LOS, supports wireless communication between Siemens S7-200, S7-300 series PLC, Schneider PLC, Mitsubishi PLC, ABB PLC etc. LS-R324 supports Modbus protocol, including Modbus ASCII and Modbus RTU protocol, PPI protocol.
LS-R324 DTU can also connect with VFD, HMI, PC for wireless communication. It supports point to point, point to multi-points wireless data transmission. Wireless solution has the advantage of keep users from wiring cables in dangerous field, easy to set up, no need program knowledge. It is a reliable and competitive solution.
2. Application Field
