Honeywell FC-TSDI-16UNI Safety Digital Input Field Termination Assembly

The Honeywell FC-TSDI-16UNI is a 16-channel safety digital input field termination assembly designed for the Honeywell Safety Manager system. It provides reliable signal connection and distribution for critical safety-related field devices across industrial process environments.

Channel Configuration and Grouping

This termination assembly features 16 input channels organized into 2 isolated groups of 8 channels. This structural separation supports segmenting critical safety loops and managing field wiring efficiently while maintaining channel organization.

Electrical Ratings and Safety Limits

The module accommodates a maximum voltage of 50 Vdc under IEC 61010-1 (1990) overvoltage category 3, or up to 150 Vdc under overvoltage category 2. Each circuit is protected by a 250 mAT slow-acting fuse measuring 5 × 20 mm, safeguarding connected inputs against overcurrent conditions.

Mechanical Installation and Wiring

Designed for standard installation, the unit mounts directly onto DIN EN rails, supporting TS32 or TS35 × 7.5 profiles with a used rail length of 91 mm. The integrated screw terminals accept maximum wire diameters of 2.5 mm² (AWG 14), requiring a strip length of 7 mm and a tightening torque of 0.5 Nm.
