Relay Outputs Options

The SLM102 has four relay outputs, related at 3A. These can be used for alarm/trip events. The use of these relays is totally field configurable, for the parameter on which to operate, the value on which to trip, the delay offer which to trip and the value at which to open. This enables the SLM102 to be used as a maximum demand controller.

Communication

EthernetThe SLM102 has a standard Ethernet-TCP/IP connection. Multiple socket Ethernet connectivity enables the unit to respond to as many as 12 different requests. The SLM102 can act as a small web-server.This on-board web-sever, offers quick and easy access to basic measurement, without special software. Built-in web pages display a range of power, energy and basic power quality information through any web enabled device. It also supports MODBUS-TCP/IP protocol.

Electrical Power Meter

The electrical power meter, Xpert is a micro-controller based unit which measures various electrical parameters, and sequentially displays on a 128X64 backlit LCD.

The unit measures the three phase voltages, currents, frequency, power factors, individual Harmonic data as Histogram including Total Harmonic Distortion as well as individual current and voltage waveforms for all three phases. Based on these inputs, the system KVA, KW and KWh can also be calculated.

For the correct operation of the unit, the only basic care required is to ensure that the phase sequence of the three phases is R-Y-B and the polarity of the CT secondary is correct.

The unit is fully solid state and will give years of trouble-free service once installed correctly.
