Allen Bradley 1734-VHSC POINT I/O Very High Speed Counter Module

FAQ

Q1. What is the 1734‑VHSC used for?
It is a very high‑speed counter module for counting pulses or encoder signals at up to ~1 MHz.

Q2. How many counter channels does it have?
It supports one high‑speed counter channel with A/B/Z inputs.

Q3. What signal types can it process?
It processes encoder signals such as quadrature (A/B) with optional Z indexing.

Q4. What input voltage does it expect?
The input section is designed for 24 V DC encoder/pulse signals.

Q5. Can it provide outputs?
Yes — it includes one isolated pair of outputs capable of up to 0.5 A at 24 V DC for compare or control functions.

Q6. What frequency range does it support?
It supports selectable count ranges around 250 kHz, 500 kHz, and 1 MHz for high‑speed applications.

Q7. Does it require a terminal base?
Yes — it requires a compatible POINT I/O terminal base such as 1734‑TB or 1734‑TBS.

Q8. What are the physical dimensions and weight?
Its approximate size is 75.5 × 12.0 × 56.0 mm and it weighs about 0.03 kg.
