Introduction / Overview
he 24-RM1 offers dual power relays capable of mains power switching. hese relays can be configured as
high, low or window alarms and can be associated with a group of up to 8 24 acquisition modules per relay.
Relays can operate when the sum of the assigned acquisition modules reach a setpoint or when any of the
modules reach the setpoint. here is also a mode where the difference between the lowest and highest value is
compared to the setpoint. his is ideal for applications where you are looking for a group of weights to be
within a certain band. i.e. balancing four corners of a weigh scale or a hanging truss.
Relays can be latched and a digital input or external command can be used to reset them.
An alarm/error signal relay is operated if communication is lost or other selectable errors occur and this alarm
resets once the source of the alarm or error is removed.
his module is supplied in an IP65 sealed ABS case but a DIN rail option is available.
he state of the power relays during an error can be selected.
Communications Overview
he 24 range of telemetry devices each have a factory set unique ID.
Data is shared between devices using Data Provider messages. A device generates these messages which can
then be used by many other devices simultaneously.
hese messages ( or packets ) of information contain a single value of data and each is identified by a Data
Tag.
he Data Tag should be unique for each message.
ID
Identi ies each device
Each device has a unique ID that is factory set. his is represented as a 6 character hexadecimal
number consisting of the digits 0 to 9 and the letters A to F.
I.e. FFD3BE
Data Tag
Id
enti ies each Data Provider message
A Data Tag consists of a 4 character hexadecimal number consisting of the digits 0 to 9 and the
letters A to F. he Data Tag can be changed by the user but the factory default is to match the
last 4 characters of the device ID.
I.e. An acquisition device of ID FFC12B would have a default Data Tag of C12B .
When a device consumes data (i.e. a handheld displaying data from an acquisition device) all it is doing is
listening to all of the Data Provider messages and selecting the one it wants to use. It then extracts the data
and displays it.
Some devices that use Data Provider messages also need to know the ID of the device providing the data. his
is necessary if that device needs to specifically wake the data providing device as opposed to using a broadcast
wake that will wake all devices on the same channel and using the same encryption key.
Pairing offers an automated method of hooking a provider and consumer of data together. However, some
devices may require you to manually enter Data Tag and ID information so it would be beneficial to the user to
understand the above mechanism.
Configuration Overview
You need to determine the Data ags of all acquisition modules that are to contribute data to this relay
module.
Each relay can use the value of up to 8 inputs which are, depending on the mode selected, used to generate a
value that is checked against your setpoint.
he toolkit allows you to see the calculated value of the selected set of Data ags. In the case of ‘sum’ mode
this will help in determining whether you want to apply an offset. his may be useful to effectively ‘zero’ the
input total to make calculating the setpoints easier.

Getting Started
o be able to see the totals from acquisition devices supplying data to the 24-RM1 and to avoid entering error
mode due to timeouts, we must first ensure that the appropriate modules are transmitting their values at a
suitable rate such as the default of 3 per second. hen we can configure the 24-RM1 to use the data from
these devices.
Configuration must be done with the 24 oolkit software and a base station.
Connections & Indicators
You will need to connect power to the 24-RM1 for it to operate. Only power is required to enable
configuration using a base station and the appropriate toolkit software.
LEDs

T 4-RM1 Operation
he 24 RM1 can accept 8 24 data inputs for each of the two relays, the total of the inputs compared to the
set point and mode of the relay channel affects whether the relay is energised or not. In addition when
considering the use relays attention should be paid as to what state the system will be in when the power is
off. he diagram below outlines how wiring and normal and inverse modes influence the state of relays.
(COM = Common, NO = Normally Open, NC = Normally Closed)
KEY:
Increasing Value _____ Relay Energised _____ Alarm Activated
Decreasing Value --------- Relay Unenergised ______ Alarm Deactivated
Relays can change state due to the following events:
 Arrival of 24 data from user defined 24 device that causes the relay output to trigger.
 riggering of digital input 1 or 2 (switch input) which if configured reset latched relays
 Arrival of data from a specified data tag can reset latched relays.
 A change in error state of a module specified in a relays list of inputs
he 24-RM1 also features a third Alarm relay. he Alarm relay is energised from start up, (connection made
between COM and NO). he relay de-energises if an error is detected, an error is classed as a timeout and
optionally can include Integrity error or low Battery. he Alarm Relay will return to normal once the source of
the error is removed.

Installation
Overview
Radio performance at microwave wavelengths is very dependent upon the operating environment; any
structure within the operating region of the radios will give rise to three effects:
Obscuration. Obscuration will result in reduced range and occurs when an obstruction masks the line-of-sight
between radios.
Aberrations to the horizontal and vertical space patterns. Distortion of these patterns may occur if
structures or objects are placed in the near or intermediate field of the antenna. he effect will be to distort
the coverage patterns, adversely affecting range and link quality.
Re lection. Any object placed in line-of-sight of the transmit antenna will result in signals arriving at the
receiver by an indirect path. Degradation of performance due to reflection (multipath effects) appears as
reduced range or poor link quality.
Any of the above will cause poor RSSI figures, an increase in the packet loss rate and in extreme cases
complete loss of signal. Fortunately, if consideration is given to these effects at the integration stage then a
good quality link will be obtained.
Guidelines or product design:
When selecting materials for product enclosures, preference should be given to fibreglass, light coloured ABS or
Polypropylene; at the wavelength of 2.4GHz radio other materials will adversely affect the signal by
attenuation, refraction or change in polarisation.
If the application demands that the radio is fitted inside a metal enclosure then ensure that the specified
clearances are maintained around the antenna and design in a fibreglass RF window at least as large as the
clearance dimensions but ideally as large as possible.
RAD24i radios fitted inside a product should be oriented so that the chip antenna will be vertical when the
product is in its normal operating position.
Guidelines or installation:
When planning installations ensure that line-of –sight between nodes is maintained and that objects or
structures are kept at least one metre away from antennae wherever possible.
o avoid poor link quality between a RAD24i radio and a handheld device ensure that the RAD24i is mounted so
that the chip antenna is vertical. Improvement may also be obtained by altering the height above ground of the
RAD24i; a small increase or reduction in antenna elevation will often improve reception.
Range underwater is only a decimetre or so depending on packet rate. Best performance underwater is
obtained by using low packet rates and immersing water-proofed antennae rather than water-tight enclosures
containing the antennae.
