Channel-to-Channel Isolation & Cold Junction Compensation (CJC)
The module accepts digital pulse inputs up to 20 kHz across 2 independent channels for high-speed flowmeter accumulation and encoder tracking. Galvanic channel-to-channel and channel-to-backplane isolation barriers decouple the 24 VDC nominal field circuits (sink/source) from internal processing logic, blocking voltage spikes and ground loop noise. Integrated signal conditioning provides a 10 kOhm typical input impedance to preserve pulse edge transitions across field transmission lines.
Frequently Asked Questions
Q: What is the maximum input frequency limit supported by the 8C-PCNT02 pulse input channels?
A: The module processes high-speed digital pulse signals at frequencies up to 20 kHz per channel.
Q: How does the 8C-PCNT02 isolate high-voltage field transients from the backplane?
A: The hardware incorporates galvanic isolation barriers providing both channel-to-channel and channel-to-backplane protection.
Q: What field wiring configurations are compatible with the 8C-PCNT02 input circuits?
A: The input channels support 24 VDC nominal digital pulse signals in both sinking and sourcing circuit configurations.
Field Installation Guidelines
- Turn off main power to the Series 8 universal I/O carrier baseplate prior to inserting or removing the 8C-PCNT02 module.
- Wear an ESD grounding wrist strap throughout handling to prevent static discharge damage to internal components.
- Align the module housing with the carrier guide rails and push firmly until side retention latches click into place.
- Route high-speed pulse signal lines using shielded twisted-pair cables separate from AC power lines to avoid inductive noise.
- Terminate all cable shields at a single point on the cabinet earth ground bar.
