Description
5-CH 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.
