TECHNICAL DATA
DESCRIPTION
● Rated supply voltage 230 VAC
● Compatible with EXTA LIFE system control-
ler and transmitters
● With 4 output channels (4 x potential-free
NO contacts)
● Two-way transmission with an indication of
each output status in the application
● Programmable output status after supply
voltage loss,
● 4 programmable external inputs
● For connecting monostable or bistable con-
nectors
● 4 operating modes when working with trans-
mitters (activate/deactivate, bistable, mon-
ostable, time),
● 2 operating modes when working with a
controller (activate/deactivate, time),
● Independently programmable time for radio
transmitters, external inputs and for control-
ler,
● Times assigned independently for each out-
put
● Software can be updated remotely
The ROM-24 modular radio receiver is the
nal element of the EXTA LIFE system which
allows individual control of any four devices/
circuits. Outputs take the form of four relays
with normally open terminals with maximum
load rating at 5 A. This enables the control of
low voltage circuits (for example 12/24 VAC/
VDC) and high-voltage circuits (230 VAC). The
receiver is good for remote actuation of other
devices. You can also use it for feeding control
signals. The ROM-24 receiver is also suitable
for controlling solenoids in heating systems.
Based on duplex communication between the
controller and receivers, the mobile applica-
tion always shows the current status of the
receiver. This communication method enables
the operator to change the specic parameters
of the receiver and add receivers remotely (i.e.
without actual access to the receiver). Thanks
to the frame encryption algorithm implemented
control safety is guaranteed. The ROM-24 in-
stalled outside a controller may be controlled in
parallel using the EXTA LIFE system’s transmit-
ters. You can register more transmitters with
a receiver to enable independent control from
several locations. Additional congurable cable
inputs increase the functionality of the control.
The receiver has a built-in remote software up-
date from a controller. The product is designed
for installing in switchgears using a TH35 (DIN)
bar. With removable antenna to enable the con-
nection of an external antenna.
