SED2 Variable Frequency Drives
Siemens Industry, Inc.
Description
The SED2 variable frequency drives are designed
specifically for HVAC applications. The SED2 supports a
wide variety of digital and analog I/O for diverse control
capability. Built-in PID features control pumps and fans, and
an integral system protocol can interface P1/N2 networks.
Using the SED2 multi-level parameter access, operators can
quickly pinpoint relevant data.
Features
• Built-in SBT P1 and JCI N2 (Metasys®) building
automation system protocols for easy network
integration
• LON Interface and Modbus Interface optional
• Low harmonics design reduces noises and
interference eliminates need for filters/reactors in
most installations
• Built-in PID for fast and accurate pressure control
• Pump staging for open loop, constant pressure, and
constant flow-type applications
• Multi-level program access
• Belt failure detection with or without an external
sensor
• Service mode for applications requiring continuous,
uninterruptible operation
• Accepts a wide variety of digital and analog I/O types,
including direct Ni 1000 RTD sensor level inputs
• One common interface throughout all power ranges
• Optional Advanced Operator Panel for
uploading/downloading parameters
• Full form C relay contacts for digital outputs
