TT-NRM<strong>TraceTek</strong> Network Relay ModuleDescriptionThe <strong>TraceTek</strong> TT-NRM Network RelayModule provides the capability toadd up to 320 individual alarm relaysto a <strong>TraceTek</strong> TTDM-PLUS / TTSIMleak detection network. The TT-NRMcommunicates with the TTDM-PLUSvia the same RS-485 network used <strong>for</strong>TTSIMs. The TT-NRM can be installed ina wide variety of configurations, allowingmany leak detection system layoutpossibilities.ExpandableThe TT-NRM is supplied as a base unit(with power supply, communicationsinterface, DIN rail and end blocks)and separate relay modules. Eachrelay module contains 2 independentlyaddressable relays. Up to 16 relaymodules can be installed on each baseunit, and up to 10 base units can beconnected to a single TTDM-PLUS. Theleak detection network can be expandedat any time with minimal ef<strong>for</strong>t.VersatileThe TT-NRM can be installed in largepanels, or wall mounted in its ownoptional enclosure. TT-NRMs can becentrally located with the TTDM-PLUS, ordistributed throughout the leak detectionnetwork to minimize wiring costs. TheTT-NRM can be used to operate valves,control audible or visual alarms, orinterface with other control systems.1.25 in.(32 mm)1.5 in.(38 mm)2 in.(75 mm)0.5 in.(12 mm)0.5 in.(12 mm)ONTxDRxDCRC24V 0V L L L L L LLL4 in.(100 mm)IO/RNIO/ERAddress x 1NNNNNNNNx 10750-312750-512 750-512 750-512 750-6001.4 in.(35 mm)Power supplyRS-485 networkconnection moduleNetworkprocessorRelaymodulesEndterminationWidth= 5.0 in. + 0.5 in, per relay module (+ 3.5 in. <strong>for</strong> optional power supply)= 127 mm + 12 mm per relay module (+ 90 mm <strong>for</strong> optional power supply)Technical In<strong>for</strong>mation Network compatibility TTDM-PLUS / TTSIM networksRelays Number Up to 32 Form A contacts per TT-NRMVoltage rating 250 Vac, 30 VdcCurrent rating 1 AmpIsolation2.5 kVEnvironmental Ratings Storage Temperature -25 °C to 85 °COperating Temperature 0 °C to 55 °CHumidityIngress Protection5% to 95% non-condensingIP 2XPower requirements Supply voltage 110~240 Volts, AC (50/60 Hz)Power consumptionOrdering in<strong>for</strong>mation Catalog number DescriptionBase unit TT-NRM-BASE Base unit with power supply,communication interface and 1 relay outputmodule (2 relays)Relay modules TT-NRM-2RO Relay output module with 2 relays6 W
