Honeywell FS-TSAI-1620M Safety Manager Analog Input Module
The Honeywell FS-TSAI-1620M is a 16-channel analog input module engineered for Honeywell Safety Manager systems. It conditions and converts field analog signals for process monitoring in safety-critical and standard industrial control environments. Arranged into two isolated groups of eight channels sharing a common 0 V connection, the module supports both active and passive 0-20 mA and 4-20 mA current transmitters.
Signal Conditioning and Transmitter Interfaces
Each input channel incorporates a high-precision 250 ohm resistor (±1%) that provides linear current-to-voltage signal conversion with an overall accuracy of ±0.1% of full scale. Integrated current-limited power distribution allows the module to safely power passive field transmitters. Interfacing with control hardware is accomplished using SICC-0001/Lx system interconnection cables, while individual shield terminals are provided for each signal line to reduce noise interference.
Electrical and Mounting Specifications
The unit operates from an external 24 V DC power supply, with dedicated screw terminals provided for external power monitoring. Designed for DIN EN rail mounting (TS32 / TS35 x 7.5), the compact housing measures 210 x 70 x 60 mm and weighs 0.2 kg. It is rated for extreme operating temperatures ranging from -40 deg C to +85 deg C and complies with Class I, Division 2 standards for hazardous locations.
