1. Description
MCR-SLP-1/5-UI-0(-SW) passive current
transducers convert sinusoidal alternate currents from
1 and 5 A into analog standard signals of 0…20 mA or
0…10 V. Modules acquire the necessary power for
signal conversion from the measuring circuit so that a
separate supply is not required for the transducer.
The MCR-SLP-1/5-UI-0-SW current transducer has
an additional limit monitor. The limit value and an alarm
suppression time are set using two potentiometers on
the front of the housing.
One Form A and one Form B contact are available for
the signaling on the output side. The appropriate
switching state is displayed using LEDs.
Both module versions are electrically isolated from
one another on the input and output side.
Safety Note:
MCR-SLP-1/5-UI-0-SW passive current transducers
are
not
suitable for safety circuits because there is no
response at the relay output if the input current fails.

using a screwdriver

3.2. Jumper Position 1

The 0-20 mA output signal is received by connecting
terminal points

and

. The maximum load is 750
Ω
.

If the
0-20 mA current and the 0-10 V voltage
signal are required simultaneously
, this can be
implemented by connecting the terminal points
according to the diagram opposite:
Terminal points
9
and
0
, are used to close the
current path.
The voltage signal 0-10 V can be tapped (by leading
back the current via the internal 500
Ω
resistor) on the
output side of connections
0
and
!
.
Since the total of all loads in the current path must
not exceed 750
Ω
, a maximum external load of 250
Ω
is to be maintained for this connection method.
In the voltage path, loads of 500 k
Ω
must not be
exceeded. Additional measuring errors, which must be
taken into account, can be found in the Technical Data.

4. Settings (SETPOINT/TIME)
for MCR-SLP-1/5-UI-0-SW
The desired current limit value is set for the
MCR-
SLP-1/5-UI-0-SW
module using the SETPOINT
potentiometer.
The TIME potentiometer enables an additional
alarm
suppression time
of 0.2 – 6 seconds.
This means that the relay is only activated if the
current limit value is still being exceeded after the
alarm suppression time has elapsed.
This function is useful, for example, if on starting AC
motors, no alarm is to be triggered due to the high
startup current.
