The ISS-105 IS Super Cell
is a “smart” five-channel intrinsically safe relay and pump controller. The IS Super Cell can be configured for a wide variety of applications including alternating or non-alternating duplex, duplex separate pump stop (SPS), triplex and quadplex applications. It can be set up for pumpup or pump-down applications or can be used as a five-channel relay.  The IS Super Cell has a long list of features that are needed for multiple pump applications. The IS Super Cell can indicate low, high and outof-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 IS Super Cell 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.
Five-channel intrinsically safe switch, din rail mount, programmable for alternating/control of 2, 3 or 4 pumps or 5-channel relay, optional 5-channel switch only (-ISO)
