FAQ
Is this module compatible with older FIO backplanes?
No. The module is designed exclusively for N-IO architecture; older FIO-series backplanes are not supported.
Can output channels be configured for voltage instead of current?
No. The module outputs 4–20 mA current only. For voltage-level control, use an external I/P converter or a dedicated voltage-output module.
