Detailed Product Overview
The F 6706 is a classic HIMA analog output module intended for safety-related applications. It converts digital values from the safety controller into precise 0/4…20 mA current signals. Each output channel is individually galvanically isolated and incorporates safety isolation, allowing the module to be used in systems requiring high integrity analog outputs.
The module supports both source and sink modes, giving flexibility in field wiring. In source mode the maximum burden is 750 Ω (including cable resistance). In sink mode the burden limit depends on the external source voltage UQ. Resolution is 12 bits, with the digital value 3840 corresponding to 20 mA.
Accuracy is specified as ≤ 0.1 % basic error at 25 °C and ≤ 0.4 % operating error across the 0…60 °C range. The outputs remain at a very low residual current (≤ 20 µA) when the module is in the basic/reset state. Maximum recommended cable length is 1000 m, subject to burden limitations.
The module occupies 4 TE in the HIMA rack and is powered from the system 5 V logic supply (40 mA) and 24 V field supply (100 mA).

Dimensions, Mounting & Connection Notes
The F 6706 is a plug-in module requiring 4 TE of rack space. Field connections are made according to the official HIMA pin assignment for the module. When operating in sink mode, an external voltage source (10–30 V) must be provided. Ensure the total burden (including cable resistance) remains within the specified limits for the selected mode. Follow HIMA guidelines for shielding and earthing of analog circuits.
FAQ
What is the HIMA F 6706?
It is a safety-related analog output module that provides isolated 0/4…20 mA current outputs for HIMA planar systems.
What output range does it support?
0/4…20 mA, with 12-bit resolution (0 = 0 mA, 3840 = 20 mA).
Can it operate in both source and sink modes?
Yes. Source mode burden is limited to 750 Ω; sink mode burden depends on the external source voltage.
What is the accuracy?
Basic error ≤ 0.1 % at 25 °C; operating error ≤ 0.4 % over 0…60 °C.
How much rack space does it require?
4 TE.
What are the power requirements?
40 mA from the 5 V supply and 100 mA from the 24 V supply.
Verification & Troubleshooting Notes
Confirm the selected operating mode (source or sink) matches the field wiring and that the total burden is within limits. Verify that both 5 V and 24 V supplies are present and within tolerance.
Check residual output current when the channel is commanded off (should be ≤ 20 µA). If accuracy or stability issues occur, inspect cable length, shielding, and burden resistance. Refer to the official HIMA documentation for the complete connection diagram, scaling details, and any specific safety application notes for the F 6706.
