ISS-105 SERIES  
Five-Channel Intrinsically Safe Switch  
Description  
The ISS-105 is a “smart” five-channel intrinsically safe relay and  
pump controller. The ISS-105 can be configured for pump-up or  
pump-down applications or as a five-channel relay covering a  
wide variety of applications.  
The ISS-105 has a long list of features that are needed for  
multiple pump applications and can indicate low, high and  
out-of-sequence alarms. If an out-of-sequence alarm occurs,  
the skipped pump(s) will be started as intended.  
The Model ISS-105 can be set-up to do non-alternating  
control, alternating control and alternating control with one  
non-alternating pump. The non-alternating pump is intended for  
use with an emergency or jockey pump. The ISS-105 can start an  
emergency pump once every 50 cycles to keep it working freely.  
Using the built-in DIP switches, individual pumps can be disabled  
when taken out of service for repair or maintenance.
