CC-PDIH01 Digital Input High Voltage Module 120VAC 250VAC Series C

CC-PDIH01 Digital Input High Voltage Module for Series C I/O

The CC-PDIH01 high-voltage digital input module brings 32 discrete input channels to Experion Series C systems. It reads 120VAC, 125VDC, or 250VAC field signals depending on the IOTA fitted. One IOM serves both voltage classes, so spare stock stays lean. Optical isolation guards the logic side. Extensive onboard diagnostics protect data integrity. This module suits plants running legacy high-voltage field devices on Series C racks.

Key Engineering Features

• 32 input channels in a single IOM slot
• 1500 VAC RMS / ±1500 VDC field-to-logic isolation
• Optical isolation technique for noise immunity
• Full internal diagnostics for data integrity
• Optional redundancy, except CC-TDI151
• Input direct/reverse configuration
• Shared IOM across 120VAC/125VDC and 250VAC variants

Technical Data

• Model: CC-PDIH01
• Function: Digital Input High Voltage
• Channels: 32
• Isolation: 1500 VAC RMS or ±1500 VDC, optical
• 120VAC IOTA: CC-TDI110 (9 in, non-redundant), CC-TDI120 (12 in, redundant), CC-TDI151 (12 in, PROX, non-redundant)
• 240VAC IOTA: CC-TDI220 (9 in, non-redundant), CC-TDI230 (12 in, redundant)

Input Thresholds and Timing

• CC-TDI151: 90-132 VAC RMS, pickup 90V, dropout 20V, 25 ms delay, 47-63 Hz
• CC-TDI110 / CC-TDI120: 90-132 VAC RMS or 100-138 VDC, pickup 90VAC/100VDC, dropout 25V, delay 25 ms AC / 10 ms DC
• CC-TDI220 / CC-TDI230: 180-264 VAC RMS, pickup 180V, dropout 50V, 25 ms delay, 47-63 Hz
• Sense current ON: 1.0 mA to 10 mA RMS depending on IOTA
• Sense current OFF: 0.32 mA typical, 2.0 mA max on PROX

Installation Notes

• Match the IOTA to the field voltage before wiring.
• Confirm 9 in or 12 in carrier slot clearance.
• Keep field wiring away from logic cabling.
• Wire reverse input logic only after checking the loop.
• Verify isolation before first power-up.

Commissioning and Maintenance

• Run a channel-by-channel input test at the field voltage.
• Check pickup and dropout points against the table.
• Review diagnostics for stuck or noisy channels.
• Replace IOTA fuses only with rated parts.
• Log redundancy status on each shift.

Diagnostics

• Continuous internal self-checks on all 32 channels.
• Fault flags report wiring and channel errors.
• Optical isolation limits cross-channel faults.
• Diagnostics help isolate field-side problems fast.

FAQ

Q: Which IOTA do I need for 250VAC signals?

A: Use CC-TDI220 or CC-TDI230. The 250VAC range runs 180-264 VAC RMS. Check the carrier slot depth first. Many sites order a spare IOTA with the module.

Q: Can I run redundancy on CC-TDI151?

A: No. CC-TDI151 is non-redundant. For redundancy, pick CC-TDI120 or CC-TDI230. Engineers often pair redundant IOTAs with critical trips.

Q: How do I confirm a channel is truly ON?

A: Check sense current and pickup voltage. ON current runs 1.0 mA to 10 mA RMS by IOTA. Dropout stays at 20V to 50V. A clamp meter plus a loop test settles it quickly.

Q: How do I choose between 120VAC and 250VAC versions?

A: Match the field voltage first. Then check the IOTA length and redundancy need. The IOM is shared, so only the IOTA changes. This cuts spare parts count.

Q: What causes slow input response?

A: Input filter and isolation add up to 25 ms delay. On 125VDC it drops to 10 ms. Long field cables add more. Test with a scope if timing is tight.
