Li-ion Tamer LT-CTR-SML GEN 3 Controller Module

LT-CTR-SML serves as the control module of the Li-ion Tamer GEN 3 gas detection system, the central network point where sensor signals from across an installation are aggregated. Detection nodes reach the module through hubs and switches, placing management and monitoring of the whole system at a single position, and Johnson Controls carries the controller in the GEN 3 cross-reference list as A163821J25.

Connection to a BMS or other control systems runs over two output arrangements: relay with serial Modbus, and relay with Modbus TCP/IP outputs. For fixing to DIN rail, the matching kit is LT-CTR-SML-DMK (A163821J26), the DIN-rail mounting kit listed for this controller.

Around the controller, the GEN 3 range takes in LT-SEN-M3 monitoring sensors (A163821J27) and LT-SEN-R3 reference sensors (A163821J28); hubs LT-ACC-HUB-POE, LT-ACC-HUB-PWR and LT-ACC-HUB-MKT; ethernet switches LT-ACC-ETS-5, LT-ACC-ETS-8 and LT-ACC-ETS-16 in five, eight and sixteen-port sizes; optional PoE switches LT-ACC-POE-4, LT-ACC-POE-24 and LT-ACC-POE-24-ADR for system power distribution; RJ45 network cables LT-ACC-NCL-3 through LT-ACC-NCL-100; and the sixteen-port relay ethernet output LT-ACC-ERO-16 with its LT-ACC-ERO-MKT DIN-rail mount kit. Power supplies in the range are the LT-ACC-PWR-12 at 12 VDC and LT-ACC-PWR-48 at 48 VDC, the former listed as typically powering the controller. Physical wiring and terminal connections are covered in the installation manual.
