Rayfull SY20M single-phase DIN rail energy meter with a built-in load relay, 80A direct connection and RS485 Modbus RTU. The relay can be opened and closed remotely over RS485 or from the front panel, and can trip automatically on programmable alarm limits, which makes it suited to tenant disconnect and load control on sub-metered sites.
Lead time: 8 - 10 Days
