CC-PDIL51 is a component in the Honeywell Experion Series-C I/O system, a digital input module that accepts 24VDC signals as discrete inputs. The module has the following features:

Extensive internal diagnostics to ensure data integrity.
Optional redundancy configuration to improve system reliability.
An internal or external on-site power supply can be selected.
Non-hazardous field power supply for hazardous environments.
Direct/reverse input indication and electrical isolation.

CC-PDIS01

The number of input channels is 32.
The isolation technology is optical isolation with an isolation rating of 1000 VAC RMS or ±1500 VDC.
The ON sensing voltage/current is a minimum of 13 VDC or 3 mA and the OFF sensing voltage/current is a maximum of 5 VDC or 1.2 mA.
The input impedance is 4.2 kΩ.
The absolute delay through the input filter and isolation is 5 ms ± 20%.
Ensure that the maximum field resistance in ON condition is 300 Ω@15 VDC and that the minimum field resistance in OFF condition is 30 kΩ@30 VDC.
These characteristics make the CC-PDIL51 module suitable for industrial process control applications that require high data integrity and reliability.
