4x Relay Output Expansion Module for Ares 12 via 1-Wire UNI
The HW group Relay Output 1W-UNI is an expansion module that extends the functionality of Ares 12 and Ares 14 devices by enabling remote control of four NO/NC relay outputs (dry contacts). The module connects via the 1-Wire UNI bus and does not require its own network or portal connection – control is handled entirely through the connected Ares device.
Each output can be switched manually via SMS or through the SensDesk portal application, automatically in response to an alarm event from a sensor connected to the Ares device, or locally – for example, as a thermostat function, for automatically switching to a backup system, or for controlling visual or audible alarms. The Relay Output 1W-UNI is available in only one version – there are no variants or options.
Four remotely controllable relay outputs in a compact module
The Relay Output 1W-UNI adds four additional switching outputs to Ares 12 and Ares 14 while maintaining low power consumption.
4x Relay Outputs (OUT1–OUT4)
Switchable dry-contact relays (NO/NC), rated for up to 120V AC/60V DC at a maximum load current of 1000mA, with galvanic isolation.
Connection via 1-Wire UNI
Connects to the Ares device via the 1-Wire UNI bus using RJ11; no separate LAN or portal connection is required.
Remote Control via SMS or Portal
Manual switching via SMS sent to the Ares device or through the SensDesk portal application and SensDesk Mobile app.
Automatic Switching on Alarm
Each output can be triggered automatically by an alarm event from a sensor connected to the Ares device.
Latching Relays
Energy-saving latching relays reduce the module’s power consumption because power is only required during the actual switching process.
Local Control
Can be used as a local thermostat function, for automatically switching to backup systems, or for controlling alarm devices.
How the Relay Output 1W-UNI is designed
The compact plastic housing (approx. 65 x 80 x 30 mm, approx. 70g) is designed for desktop operation, features IP23 protection, and is suitable for industrial, SoHo, and IT environments at operating temperatures from -40°C to 85°C and relative humidity levels of 5–90%.
Compact Plastic Housing
Lightweight, freestanding housing with status LEDs on the top indicating the switching state of the four relays.
Two RJ11 Connectors (Bus Input and Output)
One RJ11 port connects the module to an active RJ11 port of the Ares device (bus input); the second RJ11 port allows the 1-Wire UNI bus to be continued to another sensor or module (daisy chain).
Four Relay Output Terminals (OUT1–OUT4)
Four terminal blocks with switchable dry contacts (NO/NC) for connecting external devices such as alarm sirens, air-conditioning systems, heaters, or backup power systems, up to 120V AC/60V DC and a maximum load current of 1000mA, with galvanic isolation.
Power Supply via the 1-Wire Bus
The module is powered via the RJ11 connection (5V) from the Ares device’s 1-Wire UNI bus; in some cases, an external 5V power supply is required (see “Boosting the Power Supply” below).
Sensor positions, range, and cascading
The Relay Output 1W-UNI occupies four sensor positions on the 1-Wire UNI bus, even if only two of the four relays are actually used.
- Supported devices: Ares 12, Ares 14
- Connection: 2x RJ11 (bus input plus output for another sensor)
- Maximum distance: 60 m from the active Ares port
- Included accessory: 3-meter-long 2x-RJ11 cable
- Switching update rate: 3 seconds
Note: Due to the use of latching relays, the module’s operation may be affected by vibrations. It is therefore not suitable for use in vibration-prone environments such as vehicles.
Up to two modules per active port, more with accessories
A maximum of two Relay Output 1W-UNI modules can be connected to one active RJ11 port of an Ares device. For additional modules or in the event of power supply problems, there are two ways to boost the power supply.
External 5V Adapter
The third module connected to one port uses its own external 5V power adapter.
1Wire Hub Power
The active 1-Wire port of the Ares device is distributed across multiple ports using the “1Wire Hub Power” accessory; all hub ports are supplied via a dedicated 12V power adapter.
Remote control via the Ares device and SensDesk
The Relay Output 1W-UNI does not have its own network or portal connection; control is handled exclusively through the higher-level Ares device.
SensDesk Portal
Switch the relays remotely through the SensDesk portal application once the Ares device is connected to the portal.
SensDesk Mobile
Control and monitor the status of the relay outputs while on the move using the SensDesk Mobile app.
SMS Control
Switch the outputs manually via SMS sent to the GSM/GPRS-enabled Ares device – even without LAN access at the installation site.
Alarm-Based Automation
Link the relay outputs to the alarm conditions of the Ares device so that sensor values automatically switch one or more relay outputs.
Commissioning in just a few steps
The Relay Output 1W-UNI is configured entirely through the configuration interface of the connected Ares device.
- Connect the module to an active RJ11 port (1-Wire UNI) of the Ares 12 or Ares 14 using the included 3m 2x-RJ11 cable
- If required, connect additional sensors or a second module in series (daisy chain) using the second RJ11 port
- If more than two modules are connected to one port, use an external 5V adapter or “1Wire Hub Power” for the power supply
- Connect external devices such as alarm sirens, air-conditioning systems, heaters, or backup power systems to the four relay terminals (OUT1–OUT4)
- In the web interface or configuration of the Ares device, name the relay outputs and define the switching logic
- Optional: Define alarm conditions that automatically switch one or more outputs
- Optional: Set up remote control via SMS or through the SensDesk portal and SensDesk Mobile app
Why the Relay Output 1W-UNI is the right choice
Easy Expansion
Add four additional relay outputs via the 1-Wire UNI bus.
Energy Efficient
Latching relays consume energy only during the switching process.

Manual control via SMS or portal, or automatic switching in response to alarms.
Cascadable
Up to 2 modules per active port, with more possible using accessories.
Galvanically Isolated
Safe separation between the control system and the connected load.
24-Month Warranty

Practical application examples
- Visual and audible alarms
- Air-conditioning and heating systems
- Backup power supplies / backup systems
- Devices with DI/DO interfaces in general
Practical example: A Relay Output 1W-UNI is connected to an Ares 12 used for GSM/GPRS monitoring of a technical room. If a temperature sensor connected to the Ares device exceeds the defined threshold, the Ares device automatically switches one of the four relay outputs to activate a cooling fan. In addition, the operator can manually check the system and intervene at any time via SMS or the SensDesk app, for example to switch on a backup system in the event of a power failure.
