SeaDAC Lite modules offer system designers a compact, low-cost alternative for interfacing any USB equipped computer with real world signals. SeaDAC Lite modules are designed to work with third party applications via the Sealevel SeaMAX API. For maximum reliability, all SeaDAC Lite modules include Sealevel’s innovative SeaLATCH locking USB connector design that prevents accidental...
8111 – 4 OPTICALLY ISOLATED INPUTS/4 REED RELAY OUTPUTS SeaDAC Lite 8111 modules provide 4 optically isolated inputs and 4 dry-contact Reed relay outputs. Inputs can range from 5-30VDC and provide 2500VAC RMS / 3500VDC isolation to ground, while the Reed relays provide long life switch closures that are well suited for low current applications.
8112 – 4 OPTICALLY ISOLATED INPUTS/4 FORM C OUTPUTS The SeaDAC Lite 8112 provides 4 optically isolated inputs and 4 SPDT Form C relay outputs. Inputs can range from 5-30VDC and provide 2500VAC RMS / 3500VDC isolation to ground, while the Form C relays switch up to 60VDC @ 5A or 250VAC @ 6A.
8113 – 4 OPTICALLY ISOLATED INPUTS SeaDAC Lite 8113 modules provide 4 optically isolated inputs with 2500VAC RMS / 3500VDC external isolation. Ideal for low voltage monitoring applications, inputs can range from 5-30VDC. Status LEDs display I/O activity and connection to real world signals is made via 3.5mm field removable screw terminal connectors compatible with 16-30 AWG wiring.
8114 – 4 REED RELAY OUTPUTS The SeaDAC Lite 8114 provides 4 SPST Form A dry-contact Reed relays. Reed relays offer long life performance, fast response time, and are well suited to low current devices. Each relay output has a discrete common.
8115 – 4 FORM C RELAY OUTPUTS Control and monitor a variety of devices with the SeaDAC Lite 8115. The module’s 4 channels of highly- reliable SPDT Form C relay outputs are rated for up to 60VDC @ 5A or 250VAC @ 6A. Each Form C relay has a discrete common and includes normally-open and normally-closed contact connections.
8126 – 32 CHANNEL TTL The SeaDAC Lite 8126 provides 32 channels of buffered drive digital I/O. The module addresses the 32 channels of I/O as four eight-bit ports, each programmable as input or output. Use a standard 50-pin IDC ribbon cable to connect an industry standard relay rack for PC based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems.
Depending upon your application, you are likely to find one or more of the following items useful for interfacing the 8126 to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling +1 864-843-4343. TTL APPLICATIONS...
SEADAC LITE POWER REQUIREMENTS Sealevel SeaDAC Lite modules are powered by the USB host interface and require 5VDC @ 500mA to be available on the USB port. Most computers and powered USB hubs are capable of meeting this requirement, while passive USB hubs and some laptops running on batteries may not. Check the product manual that shipped with your system or hub if you are uncertain.
Connector Pin Assignments PIN OUTS – SEADAC LITE 8111 - 8115 MODULES Depending on model, you can control and monitor up to 4 optically isolated inputs and 4 Reed or Form C relay outputs. Each Reed or Form C relay has a discrete common (ground) and each pair of inputs share a common.
PIN OUT – SEADAC LITE 8126 TTL MODULE The 8126 addresses the 32 channels of buffered drive digital I/O as four eight-bit ports, each programmable as input or output. The I/O channels are accessed via an industry standard 50-pin header connector.
SeaLATCH™ USB SeaDAC Lite USB digital I/O modules integrate the SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable (Item# CA356) with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection.
• SeaMAX API Sealevel digital and analog I/O modules supported by SeaMAX software are designed to work with third party applications via the SeaMAX API. To help simplify application development, the complete API documentation and code samples are automatically installed with the SeaMAX Suite and can be found in Windows by clicking Start ...
SEAMAX SOFTWARE INSTALLATION Proceed with installing the SeaMAX Software Suite using the software CD that was included with your Sealevel I/O module. Software drivers are also available on the product webpage on the Sealevel website at www.sealevel.com. WINDOWS 2000/XP/VISTA/7™ OPERATING SYSTEMS Do not connect the I/O module to the host until the software is installed.
To communicate with a SeaDAC Lite module, select “SeaDAC Lite” from the “COM Port” dropdown box. MAXSSD will search for any SeaDAC Lite modules connected to a USB port and display them in a frame (as shown below). A new “Digital I/O” tab will appear. If more than one SeaDAC Lite module is connected, select the one you want to test from the list and click the “Digital I/O tab”.
