CHANNEL LOGIC
One Module, Two Input Behaviors
16
Configurable channels
Channels 1 through 16 can be assigned individually as standard digital inputs or as pulse accumulation inputs for frequency measurement.
16
Dedicated DI channels
Channels 17 through 32 operate as 24 VDC digital inputs, giving the module a combined pulse and discrete acquisition role.
The 8C prefix denotes the conformally coated module variant. The uncoated counterpart is 8U-PDIPA1.

Can 8C-PDIPA1 51454471-375 count pulses on all 32 channels? No. Channels 1-16 support per-channel DI or pulse accumulation assignment. Channels 17-32 are digital input channels.
Which IOTA choices fit 8C-PDIPA1 51454471-375? The coated non-redundant choice is 8C-TDILA1. The coated redundant arrangement uses 8C-TDILB1.
Can 8C-PDIPA1 51454471-375 accept a narrow 1 kHz pulse train? The pulse channels support 0-1 kHz with a minimum 30% duty cycle and 300-microsecond minimum pulse width. The field device waveform must remain inside those limits.
Does 8C-PDIPA1 51454471-375 provide field isolation with every power arrangement? The 1000 VAC RMS system-to-field isolation applies with external user-supplied field power. Confirm the selected internal or external field-power arrangement during engineering review.
Can 8U-PDIPA1 be treated as the same environmental build as 8C-PDIPA1 51454471-375? No. Their functional role is related, but 8C-PDIPA1 is the conformally coated version while 8U-PDIPA1 is uncoated. Match the installed environmental variant and the complete part identity.
