Description

The PBT SC4 site controller is a 4th generation design based on a secure and powerful Linux computer foundation. The unit is very small, has no moving parts, and can be powered from DC (battery or fuse panel) or from a local AC utility outlet. The unit has six physical (string) inputs, with a maximum of 40 batteries in any input (240 total jars per controller). The number of monitored strings can be increased via a virtualization mechanism that maps the 6 physical inputs into as many as 32 virtual strings. The number of batteries in a single string can be increased to 240 via another virtualization mechanism that maps multiple string inputs into a single large virtual string. The site controller has extensive, user-definable set-up capabilities, including labels for every monitored element, and user-defined alarm thresholds. The SC4 also monitors float charging current on each string, as well as ripple and discharge current, using current monitoring sensors made by PBT.

In addition to monitoring the battery plant, the SC4 also has 2 powered RS-485 interfaces that are used to interface with Remote Input Modules (RIMs) and Remote Output Modules (ROMs) made by PBT. RIMs and ROMs can be used to build very extensive and powerful monitoring solutions for generators or facilities monitoring. A USB interface is provided for low-level configuration of the unit. Three form-c relay outputs are provided for local alarm indications or for remote control of other equipment.

The SC4 has several interface mechanisms built-in, including an extensive configurable web server that displays site, string, and individual jar information, charge/discharge currents, RIM/ROM information and much, much more. A full SNMP (Simple Network Management Protocol) implementation allows any SNMP compliant management software to provision the system, collect data, process alarms and perform tests. An optional DNP3 monitoring interface is available.
Other hardware features include a 10/100 Ethernet interface, a +12VDC output for powering auxiliary interface devices, a plug-in flash memory drive for data logging and a very comprehensive set of LED indicators.
The SC4 is equipped with a very extensive logging system. Many years of logged data are maintained for periodic string/battery parameter measurements, discharge performance and system events such as alarms, errors, and user login attempts. All log entries are in CSV file format and all entries are date/time stamped. Log files can be downloaded remotely from the SC4 over the network, or locally by removing and reading the USB flash drive.
The SC4 is encased in a small, high-impact, flame retardant housing that fits in a 1RU rack height. A rack bracket that holds two SC4 units side-by-side is available.
