The OME-DB-16P is a 16-channel isolated digital input daughter board. The

optically isolated inputs of the OME-DB-16P consist of a bi-directional opto-coupler

with a resistor for current sensing. You can use the OME-DB-16P to sense DC signal

from TTL levels up to 24V or use the OME-DB-16P to sense a wide range of AC

signals. You can use this board to isolate the computer from large common-mode

voltage, ground loops and transient voltage spike that often occur in industrial

environments.

2.5.5 OME-DB-16R Relay Board

The OME-DB-16R, 16-channel relay output board, consists of 16 form C relays

for efficient switching of load by programmed control. The relays are energized by

applying 5 volt signal to the appropriated relay channel on the 20-pin flat connector.

There are 16 enunciator LEDs for each relay. They light when their associated relays

are activated. To avoid overloading your PC’s power supply, this board provides a

screw terminal for external power supply.

The OME-DB-24PR, 24-channel power relay output board, consists of 8 form C

and 16 form A electromechanical relays for efficient switching of load by

programmed control. The contact of each relay can control a 5A load at

250ACV/30VDCV. The relay is energized by applying a 5 volt signal to the

appropriate relay channel on the 20-pin flat cable connector (only uses 16 relays) or

50-pin flat cable connector.(compatible to the OME-DIO-24 series). Twenty four

enunciator LEDs (one for each relay) light when their associated relay is activated. To

avoid overloading your PC’s power supply, this board needs a +12VDC or +24VDC

external power supply.

3. I/O Control Register

3.1 How to Find the I/O Address

The plug & play BIOS will assign a proper I/O address to every OME-PCI-

TMC12(A) card in the power-on stage. The IDs of OME-PCI-TMC12(A) are given

as following:

• Vendor ID = 10B5

• Device ID = 9050

• Sub-vendor ID= 2129

• Sub-device ID = 9912

We provide all necessary functions as following:

1. PTMC12_DriverInit(&wBoard)

This function can detect how many OME-PCI-TMC12(A) cards in the system.

It is implemented based on the PCI plug & play mechanism. It will find all

OME-PCI-TMC12(A) cards installed in this system & save all their resource

in the library.

• wBoard=1 Æ only one OME-PCI-TMC12(A) in this PC system.

• wBoard=2 Æ there are two OME-PCI-TMC12(A) in this PC system.

2. PTMC12_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq,*wPLX)

The user can use this function to save resource of all OME-PCI-TMC12(A)

installed in this system. Then the application program can control all

functions of OME-PCI-TMC12(A) directly.

• wBoardNo=0 to N Æ totally N+1 cards of OME-PCI-TMC12(A)

• wBase Æ base address of the board control word

• wIrq Æ allocated IRQ channel number of this board

• wPLX Æ base address of PCI-interface-IC
