Product Description
Ordering Key
This product is designed in
such a way as to replace elec-
tro-mechanical contactors in
industrial heating and motor
applications, especially when
switching is frequent. This
product is ready to mount on
DIN-rail or chassis and comes
with integral heatsink. Cage
clamp terminals are used to
ensure secure load connection
with cable up to 25mm
2
.
The RJD2A series consists of
two switching poles which are
independently controlled.
Green LEDs indicate the sta-
tus of each control input. The
relay will switch on when the
sinosodial curve crosses zero
and switches off when the cur-
rent crosses zero.

Connection example
RJD2A
Application of DC voltage across
terminals A1-A2 will activate pole
L1-T1. The top green LED indicates
the status of the control input
across terminals A1-A2.
Application of DC voltage across
terminals A3-A4 will activate pole
L2-T2. The bottom green LED indi-
cates the status of the input voltage
across terminals A3-A4.
