EX-16 Relay Expansion Cards

The EX-16 Relay Expansion card provides two (8) channel relay output ports (providing 16 relay output channels) per EX-16 card. The EX-32 relay expansion card provides four (8) channel relay output ports (providing 32 relay output channels) per EX-32 card. The first EX-16 or EX-32 card is connected to the relay expansion port on the AR-8X or AR-16 Relay Interface, the ADC-4 Analog to Digital Converter, the ADC-8, ADC-16 Analog to Digital Converter or the STA-8, STA-16 Status Input Interface cards. Additional EX-16 or EX-32 expansion cards plug into the preceding EX-16 or EX-32 card. The relay expansion port on the AR-16, the ADC-4/8/16 or the STA-8/16 may be expanded with up to (7) EX-16 or (4) EX-32 expansion cards (up to 128 relay outputs for the AR-16 or 112 relay outputs for the ADC-4/8/16 and STA-8/16). Relay port locations are selected with jumpers located on the EX-16 or EX-32 cards. The EX-16 or EX-32 relay output ports are identical to those on the AR-16 and provide standard right angle box headers (10 pin with .1″ centers) or optional locking right angle box headers. Relay cards, relay driver cards or the RCT-8 terminal blocks are connected directly to the EX-16 or EX-32 relay ports with the ribbon cables provided. The RC-20 ribbon cable (sold separately) is used to connect the EX-16 or EX-32 to the AR-16, the ADC-4/8/16 or the STA-8/16. The EX-16 or EX-32 may be ordered with optically isolated relay outputs to electrically isolate the EX-16 or EX-32 output signals (specify part number EX-16/C or EX-32/C). Includes technical reference, software examples and test software. Dimensions are 5″ by 7″. The EX-16 or EX-32 may be rack mounted with any of the 5″ by 7″ cards using the CH series card racks.

The STA-16 Status Input Interface provides two 8 channel status input ports which allow input of on/off status information into a conventional PC for a wide variety of monitoring and signaling applications. Uses include the input of on/off status information of relays, switches, thermostats, security system motion detectors and magnetic switches, smoke detectors, heating and air conditioning equipment, air flow switches, air damper position switches, pressure switches and thousands of other devices. The STA-16 also has many applications in HVAC and home automation. The energy consumption of equipment with a constant load (lighting, resistance heating, hot water heaters, etc.) is easily computed by multiplying the time on by the equipment’s KW rating. The STA-16 is ideal for use in logging energy usage or equipment performance and is also well suited for use as a security system logger (to record times doors are opened, motion detectors tripped, alarms or other events). Other uses include the input of 8 or 16 bit binary codes for interfacing to TTL or CMOS level digital signals (allowing connection to counters, parallel data bus lines and other types of digital devices and equipment). The KY-12M Keypad may be connected directly to the STA-16 status input ports for use with security systems, door entry access, remote data entry and other uses. A modem will permit the status inputs to be monitored from a remote site (or use an Internet connection). The status information is obtained by transmitting a single byte port code to the STA-16. The STA-16 then transmits back a single byte code with each bit representing the 8 inputs on that port. The status inputs are turned on by applying a small current (6 ma typical) to the LED inside the opto coupler on the STA-16 (minimum 1.5 volts required, common cathode). Optional AC opto couplers are available which will turn on in both directions, allowing for both common cathode and common anode configurations. The input voltage range defaults to a 6 to 18 volt range with a 1.8 K series resistor to the LED (the STA-16 may be ordered with other resistor values or with no resistors by specifying the /M option). The STA-16 Status Input Interface provides a relay expansion port to control up to 112 relays (using EX-16 or EX-32 relay expansion cards) and an input expansion port which allows for expansion to 144 status inputs or 32 analog inputs (using ST-32, AD-16 or AD-32 expansion cards). An optional Touch Tone input is also available. Includes technical reference, software examples and STA-16 Data Acquisition Software for Windows (for use with Windows versions 3.0, 3.1, Windows 95, 98, 2000, ME, NT, XP, Vista and Windows 7, 8). Software is also provided that allow the STA-16 inputs and/or relays to be controlled or monitored over a network (LAN, Internet, etc.).
