This energy meter with CT inputs measures
electrical energies (active and reactive) in total
or partial mode. It is equipped with a liquid
crystal digital display which allows you to view
energies, instantaneous powers (P, Q and S),
as well as currents and voltages. It also cal-
culates the power factor over 4 quadrants
and features a connection test and correction
function.

features a pulse output for
metering active energy (0 to 9,999,999 kWh)
or reactive energy (0 to 9,999,999 kvarh).

COUNTIS E53
COUNTIS E53
features a communication
function providing an RS485 connection (2 or
3 wire) with JBUS/MODBUS
®
protocol. It also
allows COUNTIS E53 to be operated from a
PC or a PLC. Furthermore, this RS485 com-
munication allows you to manage up to 4 rates,
T1, T2, T3 and T4.

to be interconnected with a PC
or a PLC over up to 1200 metres using the
JBUS/MODBUS
®
protocol.
Recommendations:
We advise using a shielded twisted pair with
general LIYCY-CY type shielding in the fol-
lowing cases:
• long network
• high number of products
• environment subject to interference
If a distance of 1200 m is exceeded and/or
there are more than 31

you will need to connect a repeater
(1 track) or a spark-gap (4 tracks) to allow an
additional connection beyond 1200 m. For
further information on connection methodo-
logy, please contact us.
Note:
A 120 ohm resistor must be connected to
the 2 ends of the connection; the resistor
can be found on the additional module.
There are other solutions (modem, TCP-IP,

The communication mode is RTU mode
(Remote Terminal Unit) which uses hexade-
cimal characters of at least 8 bits.
