Subject to change without notice WWW.CYLON.COM page 1 of 4 DS0104 rev 42 DESCRIPTION The CBT-3T6-5R is a freely programmable BACnet® Unitary Controller with native MS/TP communications support. The controller is BTL listed as a BACnet Advanced Application Controller (B-AAC) and is ideally suited for Rooftop HVAC units, Fan Coil Units, Heat Pumps, Unit Ventilators, and custom unitary equipment control. Part of Cylon’s CB Line of BACnet field controllers, the CBT-3T6-5R provides 3 UniPuts™ with Triac (configurable as inputs or outputs), 6 Universal Inputs, 5 Digital (Relay) Outputs and a dedicated input for Cylon’s CBT-STAT or UCU Room Display intelligent room sensors. APPLICATION The CBT-3T6-5R is suitable for controlling a variety of small to medium- sized HVAC equipment such as: ▪ Rooftop Units ▪ Fan Coil Units ▪ Heat Pumps ▪ Unit Ventilators ▪ Custom Unitary Equipment This controller accommodates available pre-engineered strategies or can be tailored to custom applications using CXpro ᴴᴰ programming software. BACnet MS/TP Fieldbus Supports the following configurable BACnet objects: AI/AO/BI/BO/AV/BV, Trend Logs, and Schedules 3 UniPuts with Triac Configured as analog or digital outputs, or voltage inputs along with Triac functionality that can switch a 24 V AC load 6 Universal Inputs Can be configured as analog or digital inputs with pulse counting on the 6th input 5 Digital (Relay) Outputs 3 Outputs can switch up to 240 V AC 2 Outputs can switch up to 24 V AC Cylon Intelligent Room Sensor support Up to 500 Strategy Blocks Up to 6 Trendlogs 1024 entries per Trendlog Data Security Strategy and setpoints backed up in Flash No Hardware I/O Jumpers Hardware points are automatically configured by the downloaded strategy ©ABB 2021 All Rights Reserved.

UniPuts with Triac When configured as Input: Analog Input Range: 0 ... 10 V @ 40 kΩ Resolution: 12 bit Digital Volt-Free contact, @ 25 mA not continuous When configured as Output: Analog Output 0 ... 10 V, 10 mA, 12-bit resolution Active Output 1 … 10 V for sinking 1 mA max load with 12 bit resolution. Digital Output 0 ... 10 V, 10 mA 24 V AC Triac @ 500 mA maximum. Switch neutral only. Universal Inputs Analog Input Range: 0 … 10 V @ 130 kΩ Resolution: 12 bit Temperature measurement Range: 0 °C … +50 °C (32 °F … 122 °F) Resolution: 12 bit Passive Input for a large range of temperature sensors. 10K3A1 sensors are recommended. Note: It is not recommended using Sensors with a heating dissipation constant (K factor) < 2 as this will lead to an offset error. Current input Range: 0 … 20 mA @ 390 Ω Accuracy: ±0.5% full scale [100μA] Digital Volt-Free contact, Dry Contact Note: Only Universal Input 6 supports pulse counting at below 20 Hz and a minimum pulse width of 25 milliseconds. Relay Digital Outputs Points 9, 10 & 11 are relay contacts with ability to switch 240 V AC (USA: Pilot Duty 120V AC, 72 VA). Points 12 & 13 are relay contacts with ability to switch up to 24 V AC. Maximum Load: 250 V AC, 2 (1) A resistive (inductive) for all relay contacts. Relay contacts switch single-phase only. 24 V AC output terminals Total current drawn from 24 V AC terminals is limited to 0.9 A.
