The HFX48m incorporates 24 total outputs,
comprised of:
• 8 x 4 A channels
• 16 x 2 A channels
Each channel is capable of:
• High Side output
• Open loop PWM
• Closed loop PWM with current control
The 8 x 4 A channels are also capable of
Low Side output and can be congured in
pairs for H-Bridge operation.
The HFX48m also incorporates 24 total inputs,
comprised of:
• 8 x Frequency (2 of which are capable of
measuring variable reluctance sensors)
• 16 x Analog (0-5 V, 0-10 V, 0-32 V, 4-20 mA,
and Thermistor)
• All 24 inputs can be congured to add either an
internal pull-up or pull-down resistor.
The HFX32m incorporates 16 total outputs,
comprised of:
• 6 x 4 A channels
• 10 x 2 A channels
Each channel is capable of:
• High Side output
• Open loop PWM
• Closed loop PWM with current control
The 6 x 4 A channels are also capable of
Low Side output and can be congured in
pairs for H-Bridge operation.
The HFX32m also incorporates 16 total inputs,
comprised of:
• 6 x Frequency (2 of which are capable of
handling variable reluctance sensors)
• 10 x Analog (0-5 V, 0-10 V, 0-32 V,
4-20 mA, and Thermistor)
All 16 inputs can be congured to add either an
internal pull-up or pull-down resistor.
The HFX20m incorporates 10 total outputs,
comprised of:
• 4 x 4 A channels
• 6 x 2 A channels
Each channel is capable of:
• High Side output
• Open loop PWM
• Closed loop PWM with current control
The 4 x 4 A channels are also capable of
Low Side output and can be congured in
pairs for H-Bridge operation.
The HFX20m also incorporates 10 total inputs,
comprised of:
• 4 x Frequency (2 of which are capable of
handling variable reluctance sensors)
• 6 x Analog (0-5 V, 0-10 V, 0-32 V, 4-20 mA,
• and Thermistor)
All 10 inputs can be congured to add either an
internal pull-up or pull-down resistor.
The HFX12m incorporates 6 total outputs,
comprised of:
• 2 x 4 A channels
• 4 x 2 A channels
Each channel is capable of:
• High Side output
• Open loop PWM
• Closed loop PWM with current control
The 2 x 4 A channels are also capable of
Low Side output and can be congured as
a pair for H-Bridge operation.
The HFX12m also incorporates 6 total inputs,
comprised of:
• 2 x Frequency (2 of which are capable of
handling variable reluctance sensors)
• 4 x Analog (0-5 V, 0-10 V, 0-32 V, 4-20 mA,
and Thermistor)
All 6 inputs can be congured to add either an
internal pull-up or pull-down resistor.
All 4 of the HFX controllers also integrate an
internal temperature measurement that can be
used with the IEC application environment.
