16 Relay Output Board
The DB-16R, 16 channel Relay Output Board, consists of 16 form c relays for
efficient switch of load by programmed control. It is connector and functionally
compatible with 785 series board but with industrial type terminal block. The
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. The relay are
energized by apply 5 volt signal to the appropriate relay channel on the 20-pin
flat cable connector. 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.

16 Opto-Isolated Digital
Input Terminal Board
The DB-16P is a 16 channel isolated digital input daughter board for A-82x
DAS board or any 812PG, 711 series DAS boards. The optically isolated
inputs of the DB-16P consist of a bi-directional LED with a resistor for current
sensing. You can use the DB-16P to sense DC signal from TTL levels up to
24V. You can also use DB-16P to sense a wide range of AC signals. The
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 4Vrms.
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.

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.

DB –24PR/24PRD
The DB-24PR / DB-24PRD, 24 channel power relay output board,
consists of 8 form C & 16 form A electromechanical relays for efficient
switching of load by programmed control. The contact of each relay can
control a 5A load at 250VAC/30/VDC. The relay are energized by applying
5 voltage signal to the appropriated relay channel on the 20-pin header
(DB-24PR only), 50 pin header and 37-pin D-sub connector (DB-24PRD
only). 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 provides a screw terminal for power supply. CN1, CN2,
CN3 and CN4 are terminal blocks to connect with wiring. The CN7 is used
to connect with DIO-24, DIO-48, DIO-144 or any OPTO-22 compatible
digital output port. The CN6 is used to connect with A-82XPG series
PCI-1800 series ISO-DA series, DIO-64 or any compatible digital output
port. The DB-24PRD has one 37-pin D-sub connector. The 37-pin D-sub
connector can be directly connected to PIO-D144, PIO-D96, PIO-D48 and
PIO-D24’s 37-pin D-sub connector.

24-Channel Solid State Relay Board
The DB-24SSR includes 24 normally open, or form A, solid-state relays The
board interface to filed logic signals, eliminating ground-loop problems and
isolating the host computer from damaging voltages. The user can use the
DB-24SSR to switch high voltage load, up to 240VAC and up to 4A. The relay
is energized by applying a 5-voltage signal to the appropriate relay channel on
the 50-pin header or 37-pin D-sub connector. Twenty-four enunciator LEDs,
one for each relay, light when their associated relay is activated. Because
there is a D-sub 37-pin 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 solid state relay output board.

11.5. Jumper setting
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.

11.6. Isolated Input
The normal input voltage range is 5 to 24 V AC or DC . The normal input
range can be changed by choosing suitable resistor to limit the current
through the Photo-isolator to about 10 mA(If). The default resistor is
1.2KΩ/1 W.

Ri=1.2KΩ/1W
Ri = Vin/If
Pw = Vin x If
Calculation Example:
If Vin =120V then Ri=120(V) /0.01(A)=12KΩ
Pw=120(V) x 0.01(A) =1..2W
The Ri must be replaced by 12KΩ/2W(1.2W)
