The ISS-105 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 pump-up or pump-down applications or can be used as a five-channel relay.\n\u003c\/p\u003e\n\u003cp\u003eThe ISS-105 has a long list of features that are needed for multiple pump applications. The ISS-105 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.\n\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\nLittelfuse ISS-105-ISO-4 Intrinsically Safe Relay Typical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIsolated Output Relay \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\nLittelfuse ISS-105-ISO-4 Intrinsically Safe Relay Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e Five Intrinsically Safe Input Channels Meeting UL 913 Sixth Edition\u003c\/li\u003e\n\u003cli\u003e Four Normally Open Output Relays \u0026amp; One SPDT Output Relay \u003c\/li\u003e\n\u003cli\u003e Field Selectable Pump Control Options \u003c\/li\u003e\n\u003cli\u003e Monitors Float Sequencing and Sends Signal to Alarm if\nOut-of-Sequence Condition Occurs \n\t\u003c\/li\u003e\n\u003cli\u003e High and\/or Low Alarm Options Depending on the Number of\nPumps and Settings \n\t\u003c\/li\u003e\n\u003cli\u003eOutput Contacts for Audible Alarm \u003c\/li\u003e\n\u003cli\u003e Meets IEC EMC Standards for Electrical Fast Transients (EFT),\nElectrostatic Discharge (ESD) and Radio Frequency Immunity (RFI)\n\t\u003c\/li\u003e\n\u003cli\u003eDIN Rail or Surface Mountable Allows Flexibility in\nPanel Installation \n\t\u003c\/li\u003e\n\u003cli\u003e User-Selectable Alternator\/Non-Alternator Option \u003c\/li\u003e\n\u003cli\u003e Non-Alternating Pump Option for Emergency or\nJockey Applications \n\t\u003c\/li\u003e\n\u003cli\u003e Pump Disable Switches Make it Easy to Disable Individual\nPumps when they are out for Service or Repair \n\t\u003c\/li\u003e\n\u003cli\u003e Adjustable Lag Pump Delay for all Pumping Modes \u003c\/li\u003e\n\u003cli\u003eAdjustable Delay-on-Make\/Break Timer in Five-Channel\nRelay Mode \n\t\u003c\/li\u003e\n\u003cli\u003eFinger-Safe Terminals Meet IEC 61000 Safety Requirements\u003c\/li\u003e\n\u003cli\u003e 5-Year Warranty \u003c\/li\u003e\n\u003cli\u003e Made in the USA \u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Littelfuse\/Symcom","offers":[{"title":"Default Title","offer_id":49325283770685,"sku":"MSRISS105ISO4","price":610.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/5552\/7485\/files\/msriss105_001_wbg_51cdc18b-8746-4278-bcd8-19276106035e.jpg?v=1725426497","url":"https:\/\/rcworst.com\/products\/littelfuse-model-iss-105-iso-4-4-channel-intrinsically-safe-only-switch-120v","provider":"R.C.
