Introduction The PLC-16.PCI provides 8 Form C relays that can switch and carry 2A loads making it suitable for latching power, data or other electronic signals for control applications. Eight optically isolated inputs (rated for 5-30V) are also provided to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The PLC-16.PCI is optimized for 24V DC/AC usage. The board is PCI bus specification 2.1 compliant. The PLC-16.
Before You Get Started What’s Included The PLC-16.PCI is shipped with the following items. If any of these items is missing or damaged please contact Sealevel for replacement. PLC-16.PCI Adapter Sealevel SeaI/O Software CD Optional Items Depending upon your application, you are likely to find one or more of the following items useful for interfacing the PLC-16.PCI to real-world signals. All items can be purchased from our website (http://www.sealevel.com) or by calling (864) 843-4343.
Software Installation Windows 98/ME/NT/2000/XP Installation Do not install the Adapter in the machine until the software has been fully installed. 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5. Select the Part Number for your adapter from the listing. 6.
Linux Installation Note: You MUST have "root" privileges to install the software and drivers. 1. Login as "root". 2. Mount the CDROM by typing: mount -t iso4860 /dev/hdc /cdrom Note Your cdrom may not be /dev/hdc it could be /dev/hda, /dev/hdb, /dev/hdd, or if you have a SCSI drive /dev/sda, /dev/sdb, /dev/sdc, etc. You may mount the CDROM to any location, the /cdrom is just a common example. 3. Next change to the directory where you mounted the CDROM: Ex.
Physical Installation The adapter can be installed in any 5V PCI expansion slot. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available 5V PCI slot and remove the blank metal slot cover. 4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5.
Programming the PLC-16.PCI Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included on the SeaI/O CD are driver functions for use in accessing the I/O as well as helpful samples and utilities. Programming for Windows The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL).
Input Port Port A is an eight bit input port connected to optically isolated input sensors. Each sensor can be used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is isolated (with respect to a common ground) from every other sensor, and also isolated with respect to the host PC ground.
Input Port Pin Assignments (HD44 Female) The inputs are not polarized and can be wired in either direction. Port A Bit D0 D1 D2 D3 D4 D5 D6 D7 P1 9,10 11,12 13,14 23,24 25,26 27,28 29,30 40,41 Output Ports (Form C Relays) The PLC-16.PCI provides 8 Form C (SPDT) Electro-mechanical relays. These relays have three connections: Normally Open (NO), Normally Closed (NC) and a Common. The relays are all de-energized at power-on. Data to the relays is latched by a write to the base+2 address.
Writing the Outputs The output ports are the only ports that can be written. The relays on a standard PLC-16.PCI are normally open. To close a relay a binary one (1) must be written to the appropriate bit. Reading the Outputs The relay ports can also be read to determine the status of the various relays. A read will return the ones complement (or opposite) of the value that is currently written to the port. Register Description All ports are set to input after reset or power up.
HD44 Female Pin Assignment The table below describes the pin out for the HD44 Female connector on the 8011 board. The previous pages explain Port A (Inputs) and Port C (Form C Relay Outputs) addressing and how to read and/or write to them.

Optional Terminal Block Kit (Item# KT108) Another option for termination of the PLC-16.PCI is the Terminal Block Kit (Item# KT108). This kit includes an HD44 Male to HD44 Female six-foot cable (Item# CA185) and a 28-Pin Terminal Block (Item# TB08-KT). The silk screen with diagram is shown on the following page. The CA185 cable is wired straight through, one-to-one. The terminal block groups the common connections of the PLC-16.
Silk Screen – TB08 Terminal Block The silk screen for the TB08 terminal block shows how the connections are labeled for ease in wiring and troubleshooting. © Sealevel Systems, Inc. - 12 - PLC-16.
Optional Cable Pin Assignments (Item# CA184) Part Number CA184 is an optional cable for use with the PLC-16.PCI. The CA184 has an HD44 connector that breaks out to one DB37 Female connector for Inputs and one DB37 Male connector for Outputs. This cable was designed to make our products more easily integrated into systems that may have previously used Sealevel legacy I/O interface products.
