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.

OME-DB –16P8R

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.
