Serial Bus Interface CCAT - Universal Serial Sensor Interface
Each end of the CCAT contains an RJ-11 receptacle. The twisted pair receives the analog signal input. A CCAT is almost the same size as a stick of chewing gum. Housing is black shrink tubing.
Add up to 16 Sensors to WeatherGoose
There are three analog I/O ports (C123C) on a WeatherGoose and, in some cases, this may not be enough in installations where more analog sensors are needed. The CCAT solves this by interfacing the analog voltage signal into a digital signal for use on the Serial Bus.
Up to 16 devices of these devices can be attached to the serial bus. A temperature sensor is an example of a serial bus device. Up to 16 CCATs and other digital sensors can be attached to the serial bus.
An analog to digital converter, the CCAT converts the analog signal into a digital value with a unique digital address. Each CCAT contains two RJ-11 receptacles so that they can be daisy-chained together.
Multiple Types of Configurations
CCATs can be manufactured pre-configured to what type of device they will monitor:
- Door Sensor (contacts open, closed)
- Water Sensor (levels of dampness)
- Current (0 - 30 amps)
- 5,000 millivolt (0 - 5 VDC input)
Specifications
Signalling Protocol: Dallas Semi 1-Wire
Maximum CCATs: 16 devices
Response Time: 5 seconds
Size: 3 L x 0.6 W x 0.5 H
Connectors: Two RJ-11 receptacles
Wire Type: Cat3 telephone-type wire
Model Numbers: CCAT - Door Sensor, CCAT - Water, CCAT - Current, CCAT - 0 to 5VDC
Cable Length
Aggregate cable length should not exceed 600 feet. The analog signal wire should not exceed 100 feet.
Use this table to translate the output. For example, a -48 volt input to the sensor would be displayed as 66 on the graph. The output is almost linear between 40 and 50 VDC.
To avoid home-run wiring, CCATs can easily be daisy chained using RJ-11 connectors and Cat 3 telephone-type wire.
