TSDI-16UNI Safe Digital Input FTA (24/48 V DC, NAMUR, 16 Channels)

The TSDI-16UNI module is a field termination assembly (FTA) designed to interface between the system interconnection cable (SICC-0001/Lx) and external field wiring using screw terminals. It supports sixteen channels, divided into two groups of eight channels, each protected by a 250 mA fuse in the common positive line.

Key Features:

• Interface: Connects system interconnection cable (SICC-0001/Lx) to external field wiring via screw terminals.
• Channel Grouping: 16 channels divided into two groups of eight, with each group having a 250 mA fuse.
• Compatibility: Connects to a redundant pair of SDIL-1608 modules.
• Mounting: Universal snap-in provision for standard DIN EN rails.
