SINEAX A 210 Multifunction Power Monitor.

SINEAX A 220 Multifunction Power Monitor.

A210 and A220 Power measuring instrument is suitable for control panel mounting and measures all the
important measurands in 3-phase and single-phase systems. It displays the measurands with a high
contrast 14 mm high LED display.
The instrument is also suitable for measurements in low and middle voltage systems because of the freely
programmable factors for the current and voltage transformers.
It replaces a large number of analog instruments and delivers high accuracy values.
The basic execution is an instrument with 2 S0-outputs, which can be programmed as pulse or limit outputs.

Plug able module with RS 232/RS 485 interface for MODBUS RTU

Plug able module with RS 232/RS 485 interface for MODBUS RTU and data logger

After a power supply failure all values, counter contents, displayed values and programmed

functions are available

The 14 mm high LED display ensures good readability 

An extension module extends the functionality and flexibility and supports programming and communication via an RS 232/485 (selectable) interface.

It supports data communication with a control system via MODBUS RTU and it can be added without making changes to the basic instrument. Memory and a digital input allow the monitoring and recording of average power values for a minimum of 83 days at 15 min intervals.

This function enables the load profile to be determined. Alternatively, the digital input can be used to switch between the high and low tariffs. Measurement of current, voltage, active, reactive and apparent power, active and reactive energy, neutral conductor current, power factor and frequency 4 meters for active power: Incoming, outgoing with high and low tariff 4 meters for reactive power: Inductive, capacitive with high and low tariff 5 values each for active, reactive and apparent power averages with programmable interval times

System application:

Single phase, 3-wire balanced or unbalanced, 4-wire balanced or unbalanced, 4-quadrant operation.


14 mm LED digital display; adjustable brightness 3 digits with sign, Frequency: 4 digits, Energy: 8 digits Digital outputs:

2 S0 outputs; ON = 10 to 27 mA, OFF ± 2 mA; Uext: 8 to 30 V DC pulse or trip point output

Pulse output:

Active energy and reactive energy Trip point output: Open collector

Interface module Interface:

RS 485/RS 232 switchable

Protocol: MODBUS RTU

Digital input: Synchronizing input for time stamp resp. tariff switching

Digital input, bus address, and parity are programmable

Interface and data logger module

Data logging of P, Q, S (avg. values) for the last 2 months.

Programmable values:

Trip points, Transformer ratio, Type of system, interval time Programming can be locked with a jumper at the back of the instrument.

Additional features:

It is possible to extend the A 210 with an interface module or an interface/data logger module without
opening the housing.
