PSM-ME-RS485/RS485-P Repeater
Boost, or amplify, RS-485 signals to cover longer distances with the PSM-ME-RS485 Repeater. By using differential voltage lines for data and control signalsRS-485 repeatersovercome the limitations of standard serial ports. This allows you to add 4,000 feet (1.2 km) and 32 nodes to an RS-485 data circuit. In addition, 3-way isolation protects devices from transient surges and ground loops on the data line.
The PSM-ME-RS485 repeater was developed for the high requirements of fieldbus systems. The device can be powered by wall-mount AC or snapped onto standard DIN rails and supplied with 24 V DC or AC.
The PSM-ME-RS485 repeater can be used in all common 2-wire bus systems: Modbus, RACKBUS (Endress &Hauser), SUBCONET-K (Moeller), UNI-TELWAY (Telemecanique), DANBUS (Danfoss), RS-BUS (Landis & Staefa), NET 2000 (B&R), INSUM (ABB), J-BUS (Merlin Gerin), ET-WAY (Jetter), S-BUS (SAIA) and around 60 more company-specific bus systems.
