ISS-105 5-Ch Intrinsically-Safe Switch

ISS-105  “smart” five-channel intrinsically safe relay and pump controller. It can operate in a wide variety of pumping configurations including alternating or non-alternating duplex, duplex separate pump stop (SPS), triplex and quadplex for either pump up or pump down applications.

MADE IN THE USA! 5 Year Factory Warranty

ISS-105 Super Cell has a long list of “smart” features that are needed for multiple pump applications. It can also be set up as a simple five channel intrinsically safe relay. The IS Super Cell 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 as an emergency pump or jockey pump. The IS Super Cell can start the non-alternating 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. ISS-105 must be installed in a non-hazardous area. Follow SymCom’s Control Drawing 105 for proper installation (See ISS-105 installation guide).
