Detailed Product Overview
The F 3236 is a dedicated 16-fold digital input module from HIMA intended for safety-related applications. It is designed to process 1-signals or signals originating from sensors that require galvanic safety isolation. The module meets the older German requirement classes AK 1 through AK 6, corresponding to high safety integrity levels used in process and machine safety systems.
Each of the 16 channels accepts either a current-limited 1-signal (6 mA including the contribution of the cable plug) or a standard 24 V mechanical contact. The typical response (switching) time is 8 ms. The module occupies four division units (4 TE) in the HIMA rack system.
A key feature is the continuous automatic self-test performed during normal operation. The test routines check for cross-talk between channels using a walking-zero method, verify the function of the filter capacitors, and confirm overall module integrity. These diagnostics support the high safety integrity required for the target applications.
Field wiring is connected via a front cable plug (typically Z 7116 / 3236 series). Power is drawn from both the 5 V logic supply and the 24 V field supply of the host system.

Dimensions, Mounting & Connection Notes
The F 3236 is a plug-in module occupying 4 TE in a HIMA rack. Field connections are made via the front cable plug; the official datasheet provides the complete lead marking (colour code) and test-plug diagram (Z 7201 / 3236). An earth connection is required via a flat-pin plug to the earth bar under the slot. Follow the manufacturer’s wiring and earthing instructions for proper safety isolation.

Verification & Troubleshooting Notes
Verify that the correct front cable plug and wiring colour code are used according to the official datasheet. Confirm that both 5 V and 24 V supplies are present and within tolerance.
The module’s automatic self-test runs continuously; any detected fault is reported through the system diagnostics. If a channel does not respond as expected, check the field wiring, contact type (1-signal vs. mechanical), and the integrity of the cable plug connection. Refer to the HIMA F 3236 datasheet for the test-plug diagram and detailed connection information.
