Products information
The HIMA F3221 is a CE-compliant 16-fold input module engineered for safety-critical industrial
applications, featuring built-in safe isolation to ensure reliable signal acquisition from sensors or
mechanical contacts. It is designed to interface with 24 V DC mechanical contacts or 1-signal sensors
(drawing 8 mA current, including cable plug), making it suitable for use in automation, process
control, and emergency shutdown systems—common in sectors like oil & gas, chemical processing,
and manufacturing.
Key to its functionality, the module offers 16 independent input channels with non-interacting
(isolated) signal paths, preventing cross-talk between channels and enhancing signal integrity. It
supports clear signal differentiation via switch positions: a dedicated switch sets channels for “0-
signal” or “1-signal” detection, and a pushbutton enables manual “1-signal” testing for
diagnostic purposes.
For wiring and integration, the F3221 uses a Z7116 front cable plug with standardized colour coding
for each channel (e.g., white for Channel 1, brown for Channel 2), compatible with LiYY 16×0.25 mm²
cables (750 mm length, 1 mm² cross-section for power, 0.5 mm² for signals). It has a compact 4 TE
(Terminal Equipment units) footprint, enabling seamless rack-mounted integration. With a typical
switching time of 10 ms, it ensures rapid signal response, while its dual power supply (5 V DC and 24
V DC) supports stable operation in industrial environments. Additionally, the module includes a test
plug (Z7116/3221) for simplified commissioning and fault troubleshooting, ensuring ease of
maintenance and system reliability.
