+86 153594082758C-PDIL51 Coated 24V Digital Input Module · Experion / PlantCruise Series 8 I/O
Honeywell 8C-PDIL51 51454359-175 is a coated Series 8 I/O module that accepts 24VDC field signals as discrete process inputs. The technical PDF specifies 32 input channels, allowing Honeywell 8C-PDIL51 51454359-175 to collect on/off status information from field contacts and devices for the control system.
For user-supplied field power, Honeywell 8C-PDIL51 51454359-175 operates across an 18 to 30 VDC input range. The documented ON threshold is 13 VDC or 3 mA minimum, the OFF threshold is 5 VDC or 1.2 mA maximum, input impedance is 4.2 kOhm, and the filter-plus-isolation delay is 5 ms plus or minus 20 percent.
Honeywell 8C-PDIL51 51454359-175 includes internal diagnostics for data integrity, optional redundancy, internal or external field-power selection, non-incendive field power when internal power is used, and system-to-field galvanic isolation with external user-supplied power. The PDF specifies optical isolation in the input module and 1000 VAC RMS system-to-field isolation under the stated external-power condition.
Series 8 architecture pairs Honeywell 8C-PDIL51 51454359-175 with the correct IOTA for the installed arrangement, including coated non-redundant and redundant variants. Replacement planning should confirm the exact IOM model, IOTA type, field power, terminal wiring, redundancy choice and Experion or PlantCruise configuration.
