These enclosures are offered in a White “-R2” or Beige “-R” color depending on enclosure style and designed to be mounted over a single gang junction box or hole in the wall using drywall anchors. An optional LCD Display is available in the Beige “-R” style enclosure. Screw terminal blocks are provided for making connections to your building management system. An optional 3.175 mm (1/8 in) Black foam pad with pressure sensitive adhesive is available to insulate the sensor from thermal drafts within the wall or wall surface temperature. A 1/16 in Hex driver can be used to secure the cover from being easily removed. The “LCD” option uses two temperature sensors to monitor the ambient air temperature in the space and is factory calibrated at a single point. ## **Applications** Space Temperature Sensing, Office Buildings, Schools, Colleges, Commercial Buildings, OEM Opportunities ## **Warranty** The ACI Platinum Room Series is covered by ACI’s Five (5) Year Limited Warranty. The warranty can be found in the front of ACI’s Sensors & Transmitters catalog, as well as on ACI’s website, workaci.com. ## **Specifications** **Sensor Type:** Platinum RTD **Sensor Curve:** PTC (Positive Temperature Coefficient) **Number Sensing Points:** One **Number Sensor Terminals** **A/100-2W Series** and **A/1K-2W Series:** Two (Non- Polarity Sensitive) **A/100-3W Series** and **A/1K-3W Series:** Three (Polarity Sensitive) **Sensor Output @ 0 °C (32 °F)** **A-100-xW Series:** 100 Ω nominal **A/1K-xW Series:** 1000 Ω nominal **Sensor Accuracy @ 0 °C (32 °F)** ± 0.06 % Class A ( **Tolerance Formula:** ± °C = (0.15 °C + (0.002 * |t|)) where |t| is the absolute value of Temperature above or below 0 °C in °C **0 °C (32 °F):** ± 0.15 °C (± 0.27 °F) **50 °C (122 °F):** ± 0.25 °C (± 0.45 °F) **Din Standard:** DIN EN 60751 (IEC 751) **Temperature Coefficient:** 3850 ppm / °C **Sensor Stability:** ± 0.03 % after 1000 Hours at 300 °C (572 °F) **Response Time (63 % Step Change):** 8 seconds nominal **Self-Heating | Maximum Operating Current** **100 Ω RTD:** 7 mW / °C (Still Air) | 5 mA **1 k Ω RTD:** 4 mW / °C (Still Air) | 3 mA **LCD Display Supply Voltage:** 9 V DC to 35 V DC / 24 V AC (50 Hz to 60 Hz) **LCD Display Accuracy:** ±2 °F or ±2 °C at 21.5 °C (71 °F) typical **LCD Display Descriptor:** °F (Fahrenheit) or °C (Celsius) **Number of Digits:** 3 1/2 Segment Display ## **LCD Display Life Expectancy:** 50,000 hours minimum **Set Point Specifications | Set Point Indication:** See Ordering Grid options on back of Product Data Sheet **Set Point Tolerance:** ±10 % of range **Override Options:** Short Thermistor (Default); Field (Jumper) Selectable “Dry Contact” Closure (Separate Input); Short Set Point available upon request **Operating Range:** 1.5 °C to 50 °C (35 °F to 122 °F) ## **Storage Temperature Range** **Non-LCD:** -40 °C to 65 °C (-40 °F to 149 °F) **LCD Display:** -10 °C to 65 °C (14 °F to 149 °F) **Operating Humidity Range:** 10 % to 95 % RH, noncondensing **Connections:** Screw Terminal Blocks (non-polarity sensitive) **Wire Size:** 1.31 mm[2 ] (16 AWG) to 0.129 mm[2] (26 AWG) **Terminal Block Torque Rating:** 0.5 Nm minimum; 0.6 Nm maximum ## **Enclosure Material | Flammability Rating | Color:** **“-R2” Enclosure:** ABS Plastic, UL94-HB, White **“-R” Enclosure:** ABS Plastic, UL94-HB, Beige **Product Dimensions:** See dimension drawing on this product data sheet ## **Product Weight:** - **A/1K-2W/3W-R/RS/RO Series:** 63.5 g (0.14 lb) **A/1K-2W/3W-RSO Series:** 81.6 g (0.18 lb) **A/1K-2W/3W-R2/R2S/R2O Series:** 72.6 g (0.16 lb) **A/1K-2W/3W-R2SO Series:** 90.7 g (0.20 lb) - **A/1K-2W/3W-RSO-RJ6-LCD Series:** 81.6 g (0.18 lb) **AII LCD Display Units:** 81.6 g (0.18 lb) **Agency Approvals:** CE**, UKCA, RoHS2, WEEE **Note[1] :** All LCD Display Units are not CE Compliant, but they are RoHS2 Compliant **LCD Display Supply Current/VA:** < 4 mA / 0.12 V A ## **Dimensions** **==> picture [479 x 112] intentionally omitted <==** **----- Start of picture text -----**
