This energy meter with CT inputs measures
GB
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.
Functions specific to COUNTIS E50
Le COUNTIS E50 features a pulse output for
metering active energy (0 to 9,999,999 kwh)
or reactive energy (0 to 9,999,999 kvarh).
This pulse output can be configured to the
energy type, the weight (0.1, 1, 10, 100
kwh, kvarh and 1 or 10 Mwh, Mvarh) and
the duration (100 ms to 900 ms).
Functions specific to COUNTIS E53
COUNTIS E53 features a communication
function providing an RS485 connection ( or
3 wire) with JBUS/MODBUS
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, T, T3 and T4.

General info on JBUS MODBUS
In a standard configuration, an RS485 connec-
tion allows 31 COUNTIS E53, COUNTIS Ci
and DIRIS to be interconnected with a PC
or a PLC over up to 100 metres using the
JBUS/MODBUS

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 COUNTIS E53 et
DIRIS 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,
R = 120
fibre optic...). Please consult us.
Communication
communicates using a JBUS/MODBUS
protocol, which involves a dialogue within a
master/slave structure. COUNTIS E53 beha-
1200 M
ves as a slave.
The communication mode is RTU mode
(Remote Terminal Unit) which uses hexade-
N n
cimal characters of at least 8 bits.
