Schneider Electric SLABTXX SpaceLogic SLA Room Sensor

SLABTXX: SpaceLogic SLA room temperature sensor with colour touchscreen

The SLABTXX is a Schneider Electric SpaceLogic SLA Series room unit in a glossy black wall housing. It measures temperature and returns analogue outputs, and the datasheet lists a 2.4 inch colour touchscreen, 240 x 300 pixels. Seven Star LLC supplies it as an independent supplier in Oman and the GCC for HVAC contractors, BMS integrators and fit-out teams.

The family names on the datasheets follow a pattern that we read as follows, from titles only and not from an ordering table: the fourth letter points to the housing (B black, W glossy white, S matt white), the fifth to the face (T touchscreen, L segmented LCD, X none) and the last letter to the measurement (2 for humidity plus temperature, X for temperature only).

What the SLABTXX does in a room

A room unit combines a sensing element and an operator face in one wall-mounted housing. The SLABTXX measures temperature and passes the result to the room controller as an analogue signal, while the face gives the occupant a way to see the value or adjust the set point. With temperature alone, it is for rooms where humidity control is not part of the control strategy.

The datasheet lists a temperature setting range of 10–35 °C and an operating ambient range of 0–50 °C. Place the unit on an internal wall, away from direct sun, supply-air diffusers and warm equipment, so that the reading represents the occupied zone and not a local hot or cold spot.

Controller compatibility and system fit

The datasheet lists compatibility with EcoStruxure Building Operation SmartX Room Purpose Controller programmable controllers. That is the intended controller family, and the analogue fan and configurable outputs are what those controllers read. Use with other controllers is a design decision outside the datasheet, so confirm it before ordering.

Related references in the same family include SLABTXX, SLASXX2, SLAWLX2, SLAWLXX, SLAWTX2, SLAWTXX and SLAWXX2, which differ by housing, face and humidity element. A project with mixed room types often combines several of them under one controller design.

Selection checklist

A room unit is chosen by three questions: what must it measure, who touches it, and which controller reads it. The list below turns those questions into checks that can be copied into a submittal or a purchase request.

• Measurement: temperature.
• Face: colour touchscreen.
• Housing: glossy black.
• Controller: SmartX Room Purpose Controller compatibility and output scaling.
• Supply: 24 V AC or 20–30 V DC.
• Placement: internal wall, away from sun, diffusers and heat sources.

Where several room types share one controller design, keep a schedule of references per room so that the correct housing and face reach the correct wall during installation.

Installation and commissioning

Mount the unit on the wall at the height the project drawings specify, make the screw-terminal connections, and power up. Verify the readings against a reference thermometer placed next to the sensor, and record the offset if the project requires one.

Avoid painting or sealing the housing, and keep spares of SLABTXX for rooms that cannot wait for a replacement. A cover that becomes dirty or damp during fit-out can affect readings, so protect it until the finishing work is complete.

Technical specifications of the SLABTXX

Display and user interface of the SLABTXX

The face is a colour touchscreen of 240 × 300 pixels. It shows temperature, set point and a menu-driven interface, and the occupant adjusts values by touch, so there are no mechanical buttons to wear.

When you compare references, the housing colour and the face are the visible differences, while the supply, outputs and compatibility listed on the datasheets are essentially the same across the family. Choose the face by who will use the room, not by the part number alone.

Outputs, supply and wiring of the SLABTXX

The datasheet lists analogue outputs: one for fan speed at 0–10 V and one configurable output at either 0–5 V or 0–10 V. The supply is 24 V AC at 50–60 Hz or 20–30 V DC. Connections are on screw terminals accepting two cables of 24 to 18 AWG.

Check the output scale configured in the controller against the room unit before commissioning this unit, as a 0–5 V against 0–10 V mismatch will give half-range readings. Keep sensor cabling away from power cables and use twisted pair for longer runs.
