SPSED01 (Sequence of Events Digital Input Module) Function: Similar to SPSET01, but does not process information from the time synchronization link, processes 16 digital field inputs.
Expression: Up to 63 SPSED01 modules can be operated on an I/0 expansion bus segment with one SPSET01 module.
Technical Data (SPSET01 and SPSED01) Power Requirements: +5 VDC, +5%, typical current is 350 mA.
Digital Input Channels: 16 optically isolated channels. Options for 24 VDC, 48 VDC, 125 VDC, 120 VAC (only for system control logic)
Ambient Temperature: 0°C to 70°C (32°F to 158°F)
Terminal Unit: NFTP01 (Field Terminal Panel) Function: For mounting terminal units in a 19" rack cabinet, can accommodate two termination units.
