Casambi Power Relay Controller with Programmable Dry Contact In and Out

casDouglas Diagram

casDouglas is a Casambi Bluetooth controllable single channel high-power relay driver that allows connection to reversable DC voltage relays under control of a Casambi net-work without the need for a separate power driver. The casDouglas is connected between a 12-24 VDC Class 2 power supply and can generate forward and reverse DC voltages up at the input voltage DC value. Two digital, dry contacts (no external voltages!), one program-mable input and one output are supported with 3-way operational modes. 

casDouglas connects directly to Douglas branded or equivalent circuit breakers (relays), allowing for remote control. Multiple casDouglas devices can be used in the same net-work to control different circuit breakers (relays), and can be used for other power control needs that fit the same Douglas relay electrical specifications. The digital I/O’s can be utilized as needed, as a input pushbutton and a dry contact output. 

 casDouglas can be configured with the Casambi app which can be downloaded free of charge from the Apple App Store and the Google Play Store. Different Casambi enabled products can be used from a simple single luminaire direct control to a complete and full featured light control system where many units automatically form a mesh network. 

DC VOLTAGE INPUT

 Voltage range: 12-24 VDC, Class 2
No-load input current: 30 mA, max 2000mA when relay active. Load current dependent on driven device. 

RELAY CONTROL OUTPUT

 Relay Aand Relay B form the two-wire connection (not ground)
Up to 2A if current across the Relay A and B connections 
Relay A and B reverse DC voltage to trigger the Douglas relay 
Pulsed duration programmable from 250ms to 3000ms 

DIGITAL INPUT AND OUTPUT

 Both Digital I/O’s are dry contacts only! Do not drive with voltage!
Input: Connect to dry switch to the ground terminal. In mode can be set to Normal, Inverted, or Multi-Switch to allow for switch gang operation.
Output: Connect to dry sensor to the ground terminal. Out mode can be set to Normal or Inverted.
Caution! This input should not be powered, and only used as a dry contact between the two connections.

INSTALLATION DETAILS

Connect a Class 2 power supply with 2A max of output current to the input connector of casDouglas. Make sure not to use a constant current LED driver and make sure that the cable polarity is correct. The product has one pulsed relay drive output channel, a common ground, and two dry contact connections. Connect Relay A and Relay B directly to the coil of the Douglas circuit breaker and instantly power cycle your Casambi lighting network as the circuit breaker panel. Note that multiple Casambi Vendor Parameter are present to give your system a wide control operation. 

casDouglas’s digital input can be mapped just like Pushbuttons are mapped in the Casambi application. Once you add the casDouglas to your Casambi network, navigate to the “More” button at the bottom of the app. Then press “Switches”, where the casDouglas will be shown. Press on the casDouglas that you want to configure and select which Element(s) that you wish to control as a digital con-trol. The digital input is dry contact, do not power it! Simply open or short that to ground terminal provided. Normal, inverted and MultiSwitch operations are offered. Normal wants a short to go “on”, inverted a short to go “off”, while MultiSwitch allows multiple casDouglas units to be used in tandem to work like 3-way switches. The 10 gang sets allow for up to 10 difference pairing of casDoug-las units in this mode. 

The digital output is also a dry contact, and can switch another dry contact input. The control for this will be on the Luminare screen, long press there to show the control at the bottom of the widget area.

RANGE DETAILS

The range between two casDouglas’s or between a casDouglas and a smart phone can vary depending on obstacles and surrounding material. In open air the range between two casDouglas can be in excess of 200 ft, but if the unit is encapsulated into a metal structure, the range can be only few feet. Therefore, thorough testing is high suggested. Casambi uses mesh network technology so each casDouglas acts also as a repeater. When testing the network, it is important to test that each unit can be controlled from any point of the network covered area. 

casDouglas should not be placed in a metal enclosure, such as metal junction boxes. Metal will attenuate radio signals which are crucial to the oper-ation of the product. If the product will have to installed into a junction box, make sure to use a plastic junction box. casDouglas is an ETL Listed Open-Type device which means that it will have to be used together with a Class 2 power supply with maximum output power of 100 VA. The prod-uct can be installed outside of junction box. Make sure to comply with National Electric Code in installation and when selecting installation wires.
