ISS-102 SERIES  
Two-Channel Intrinsically Safe Switch  
Description  
The ISS-102 is a two-channel, intrinsically-safe switch designed  
for multiple uses including a pump-up/pump-down (latching)  
controller or two-channel switch. LEDs indicate the state of the  
intrinsically-safe inputs and output relays and user-selectable  
options are available including a variable resistance threshold for  
float inputs.The ISS-102 enclosure is surface or DIN rail mountable.  
-LC Each input channel is active when the corresponding  
switch is closed. When the lag input (CH2) is activated, the  
output closes. Applying latching logic, the output contact  
remains closed until the lead (CH1) and the lag (CH2) inputs are  
deactivated. Sensitivity is fixed at 100kOhms with a debounce  
time delay of 2 seconds.  
-DCSThis dual-channel switch has two Form A output relays.  
Two LEDs illuminate the output state of their respective Form A  
relay. Resistance probes or switches can be used on its inputs.  
Sensitivity is fixed at 100kOhms with a debounce time delay of  
0.5 seconds.

-MC By selecting the proper functionality through the DIP  
switches, you can define a pump-up or pump-down, single or  
dual channel non-latching switch. The sensitivity adjustment  
(4.7k-100kOhms) allows you to define the input impedance at  
which the output relays (one Form A & one Form C) will change  
state, with a debounce time delay of 0.5 or 2 seconds.
