CET PMC-1220E Communication Device - Industrial RS485 Hub
About the PMC-1220E Industrial RS485 Hub
The PMC-1220E is an Industrial RS485 hub with one upstream port and four downstream ports. Not only can the PMC-1220E be used to increase the number of RS458 nodes beyond the 32 limit, it can also be used to simplify the wiring for a RS-485 network by splitting a long segment into four individual shorter segments, thus reducing labor and material costs while expanding the coverage area. Each RS485 port is optically isolated to protect the connected devices from electrical surges as a result of lightning or other electrical faults.
