Product Description

Preliminary Datasheet

Ordering Key

The SOLITRON Midi Current
Sensing is a compact, single­phase SSR that is sensitive to
variations in load conditions in
industrial heating applications.
This microprocessor-based
device is ideal for detection of
partial load failure and to
ensure the highest process
quality. Current sensing is inte­grated inside to eliminate the
need to install an external cur­rent transformer. A membrane
“button” on the front is used to
effect a simple “teach in” of the
current setpoint. Alarm delay
time is set by a potentiometer.

A drop in setpoint current of

more than 13% will trigger an
open collector alarm. In the
case of the Autoranging RJCS
(RJCSR), an open collector

alarm is triggered with a load
deviation (drop/increase) in
setpoint current of more than
13%.
Up to 50 alarm outputs can be
connected in parallel to a stan­dard PLC input. Typical condi­tions that can be detected are
heater break or open-circuit,
blown fuse, semiconductor
short-circuit and faulty power
connection.
Device over-temperature pro­tection is integrated as a stan­dard feature.
The product is ready to mount
on DIN-rail or chassis and
comes with integral heatsink.
The standard housing dimen­sions enable straightforward
replacement of alternative
products.
