Product Overview
Honeywell 621-0008 is an 8-point Pulse Input Module that counts digital pulses at frequencies up to 100 kHz. Each channel has a 16-bit up-counter (max count 65 535) and supports selectable voltage ranges of 5 V, 24 V or 48 V (overall 5–60 VDC).
Key Specs
- Channels: 8 pulse inputs
- Max frequency: 100 kHz
- Counter: 16-bit up-counter per channel (0–65 535)
- Voltage ranges: 5 V (4.5–9 V), 24 V (10–32 V), 48 V (32–60 V)
- Overall range: 5–60 VDC
- System: Honeywell IPC / special-function I/O
Why Choose This
- High-speed pulse counting up to 100 kHz
- Wide selectable input voltage ranges
- Suitable for flowmeters, proximity switches and pulse generators
- Simple processor read/reset of counters
Common Questions
- Max frequency? 100 kHz.
- Channels? 8.
- Voltage range? Selectable 5 / 24 / 48 V (5–60 VDC overall).
Mounting Steps
- Install the module in the appropriate I/O card file slot.
- Select the voltage range for each input as required.
- Wire pulse sources (flowmeters, proximity switches, etc.).
- Power up and verify counter operation from the processor.
- Implement read and reset logic in the application program.
Buying Advice
