Genset Engine Start

SENS is the industry’s leading supplier of genset engine starting chargers and best battery selectors. Engine generator sets (gensets) generate power for many buildings, industrial facilities, venues,  and military sites when utility power is unavailable.

Industrial DC Power

Power generators, electric utilities, and industrial plants operate a vast array of protective relays, circuit breakers, switchgear, and control electronics that keep all that power under control, preventing malfunctions from turning into high-powered disasters.

Battery Monitoring

Remote battery monitoring can save maintenance costs, predict impending battery failures and extend battery service life. Our systems can extend their monitoring and control capabilities to generators, chargers/inverters, HVAC systems, and building monitoring.

PBT-ROM

 

Remote Output Module (ROM)

PBT-ROM-[x][y]

The ROM is a remote output module that is designed to operate in conjunction with PBT’s battery monitoring system or with the ContactAgent general-purpose remote monitoring system.

The ROM operates with the ContactAgent or with the PBT-SC4 Site Controller hosts via the “P-Bus” powered RS485 expansion bus. The host supplies operating power and communications signaling for the ROM slave over the P-Bus using common CAT5/RJ45 interconnect cabling.

DATA SHEET

Expand through Daisy Chaining

Up to four ROMs can be operated in a “daisy-chain” configuration on each host P-Bus port. This provides a maximum expansion capability of four ROMs per ContactAgent host or eight ROMs per SC4 Battery Monitoring Site Controller. Each ROM provides four sets of remotely
controllable Form-C relay contact outputs. The relays are of the mechanically latched type, so the contact state is preserved even if power to the ROM is lost.

The status of each output for every ROM on the host controller’s P-Bus is viewable from the host’s built-in web server or via SNMP. ROM output states are also controllable via the web interface or via SNMP. LED indicators on the ROM also provide a local indication of each relay’s state.

Each ROM also contains an internal temperature sensor and an
optional humidity sensor.
