Brief Introduction:
Eastron SDM220M series is single phase two wire Din rail meter. SDM220M is multifunction meter
for measuring kWh, Kvarh, KW, Kvar, KVA, PF, Hz, dmd, V, A, etc with RS485 Modbus protocol.
The data can be transported by isolated RS485. It is provided with a nonvolatile memory system
that the reading are not lost or altered when power off. It uses advanced special recording integrated
circuit with high precision. It is highly accurate, durable, reliable, low power consumptive, without reversion,
creep-proof, antI tampering, and bilateral recording with strong overloading capability. It conforms to the
related requirements of IEC62053-21 , and pass EN61326-1:2006 and EN61010-1:2010 in world
famous Lab.

Output
Pulse Output The meter provides two pulse output, both of them are configurable.
The pulse output can be set to generate pulses to represent kWh or kVarh.
Rate can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVarh.
Pulse width: 200/100/60ms
RS485 output for Modbus RTU
