2. OME-DB-16R

16 Channel Relay Output Board

The OME-DB-16R, 16-channel Relay Output Board, consists of 16 Form C

relays for efficient switch of load by programmed control. The OME-DB-16R

can be connected to DIO-64, A-626, A82x DAS board and PCI-series

multi-function board or any other compatible DAS board with the 20-pin

connector. The relays are energized by applying 5 volt signal to the

appropriate relay channel on the 20-pin flat cable connector. The 16

enunciator LEDs, one for each relay, light when their associated relay is

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

screw terminal for external power supply.

3. OME-DB-16P

16 Opto-Isolated Digital Input Terminal Board

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

OME-A-82x DAS board or OME-812PG DAS boards. The optically isolated

inputs of the OME-DB-16P consist of a bi-directional LED with a resistor for

current sensing. You can use the OME-DB-16P to sense DC signal from TTL

levels up to 24V. You can also use OME-DB-16P to sense a wide range of AC

signals. The OME-DB-16P registers a constant logic high if the frequency of

the input AC signal is greater or equal to 1 kHz, and the voltage of the AC

signal is at least 4 Vrms. If you are using AC input signal, you should short the

AC filter Jumper. You can use the board to isolate the computer from large

common-mode voltages, ground loops, and voltage spikes that often occur in

industrial environments.

a slow response (about 5 to 10 ms) for rejecting noise or contact bouncing,

short the AC FILTER jumper.

4. OME-DB-16P8R

The OME-DB-16P8R is a 16-channel isolated/non-isolated input & 8-channel
relay output board. The isolated digital input can be used to sense 3.5V to
24V DC signal. The non-isolated digital input is used to sense dry contact.
The relay output consists of 16 form C power relays. The user 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.

7. OME-DB-24C

24-Channel Open-Collector Output Board

The OME-DB-24C has 24 channels of optically isolated digital outputs,

arranged into four isolated banks. Each digital output offers a Darlington

transistor and integral suppression diode for inductive load. The board

interfaces to field logic signals, eliminating ground-loop problems and isolating

the host computer from damaging voltages. The OME-DB-24C has one 37-pin

D-sub connector, one 50-pin OPTO-22 compatible male header and one

20-pin male header.

The transistor is energized by applying a 5 volt signal to the appropriate input

channels on the 50-pin header or 20-pin header or 37-pin D-sub connector.

Twenty-four enunciator LEDs (one for each transistor) light when their

associated transistor is activated. Because there is a 37-pin D-sub connector

on the board, the user may use it to interface to any TTL output board. In

other words, the user may use it as a general purpose open-collector output

board.

8. OME-DB-24OD

24-Channel Open Drain Output Board

The OME-DB-24OD has 24 channels of optically isolated digital outputs. The

board is the interface for field logic signals, elimination ground-loop problems

and isolating the host computer from damaging voltages. The OME-DB-24OD

has a single 37-pin D-sub connector, one 50-pin OPTO-22 compatible male

header and a 20-pin male header. The transistor is powered by applying a

5-volt signal to the appropriate input channel on the 50-pin header, the 20-pin

header or the 37-pin D-sub connector. Twenty-four indicator LEDs (one for

each transistor) are lit when their associated transistor is activated. The board

may be used to interface with any TTL output board, allowing it to be used as

a general purpose open-drain output board.

The OME-DB-24POR includes 24 normally open, Form A, Photo-MOS relays.

The board interfaces to field logic signals, eliminating ground-loop problems

and isolating the host computer from damaging voltages. The user can use

the OME-DB-24POR to switch loads up to 350 VAC and 130 mA. The relay is

energized by applying a 5 volt signal to the appropriate relay channel on the

50-pin OPTO-22 compatible connector or 37-pin D-sub connector.

Twenty-four indicators LEDs (one for each relay) light when their associated

relay is activated. Because there is a D-sub 37-pin connector on the board,

If you are using AC signal, you must short the AC FILTER jumper.

If you are using DC input signals, the AC FILTER is optional. If the

response time of input signals less than 20µs, set the filter off. If you want

a slow response (about 5 to 10 ms) for rejecting noise or contact bouncing,

short the AC FILTER jumper.
