Elspec G4401 – BlackBox Sequence of Event Recorder (SER) – 8 Digital Input at 800Hz

• (8) Digital Input at 800Hz
• (4) Digital output at 16 sample/sec
• (4) Analog 4-20mA input
• (4) Analog 4-20mA output
• Relay output

The Elspec SPG-4401-0090 Fixed BlackBox Sequence of Event Recorder logs data for post-fault analysis and features 8 digital inputs, 4 digital outputs, as well as 4 analog inputs and outputs, and relay output. The BlackBox SER is designed to replace RTUs and PLCs for energy management and substation automation. With the Fixed BlackBox Sequence of Event Recorder you can monitor the reliability of system apparatus such as transformers, circuit breakers and other critical equipment.

The front end of the unit is comprised of three modules namely the Central Processing Unit (CPU), the Multi I/O Module, and the Power Supply (PS). The functions for the CPU are mainly data compression, file handling and facilitation of communication interfaces. The CPU features an AC/DC power supply, DC/DC converter, an automatic selection of highest voltage and an ultra-capacitor ride-through for up to 25 seconds.

The Power Supply facilitates a wide range of inputs that comply with the highest standards set by the industry. The power supply module contains internal backup circuitry to hold internal voltage during momentary transients and disturbances. Thus, when powering off the unit, it continues operating for up to 1 minute. The power supply supports the following power sources: DC 100-300V; AC 100-260V, 60/50 Hz (recommended); PoE 48V.

The multi I/O module includes analog and digital I/O as well as a relay output to specifically work with your application. (G4401 includes 1; G4402 includes 2; G4403 includes 3)
