Extensions
MD82
8 digital 2 digital outputs with changeover contacts (8DI+2DO)
MLOG
TF card storage (alarm records, event records, electrical parameters and energy timing records, etc.)
MA84
8 analog inputs (class 0.5) + 4 analog outputs (class 0.5) (8AI+4AO)
MCM
1 RS485/Modbus-RTU, support master mode or slave mode
MCP
1 Profibus-DP
，
Configure this function to give MCM function, referred to as MCMP for short.
MCE
1 Ethernet, support Modbus-TCP, http, SMTP, DHCP protocol
，
Configure this function to give MCM
function, referred to as: MCME
Note:When selecting the extended function, the meter can take up to 3 modules. The modules can be the same or different, but
MCP\MCE\MLOG cannot select multiple identical modules combined, MCP and MCE only Can choose one. The installation sequence
can be arbitrary. If Ethernet or Profibus function is recommended for installation, it is recommended to install it near the A of the main
body. For the location of A, please refer to 3.3 Assembly.
