Analog Threshold Trigger

For  analog  input  operations,  an  analog  trigger  event  occurs  when  the  PCIE-1816/
1816H detects a transition from above a threshold level to below a threshold level
(falling edge), or a transition from below a threshold level to above a threshold level
(rising edge). User should connect analog signals from external device or analog out-
put  channel  on  board  to  external  input  signal  ATRG0  and  ATRG1.  On  the  PCIE-
1816H, the threshold level is set using a dedicated 16-bit DAC. By software, you can
program  the  threshold  level  by  writing  a  voltage  value  to  this  DAC;  this  value  can
range from -10V to +10V.

Figure 3.12 External Analog Trigger Source Connection

Digital Signal Connections 

The PCIE-1816/1816H has 24 digital input/output channels and they can be config-
ured as input or output channels. The digital I/O levels are TTL compatible. 

Digital Input Connections

Each digital input channel accepts either dry contact or 0 ~ 5 V

DC

 wet contact inputs.

Dry  contact  capability  allows  the  channel  to  respond  to  change  in  external  circuit
when no voltage is existed.
