Product Description P/N: 1734-VHSC24
Description
The Allen-Bradley 1734-VHSC24 is a POINT I/O Very High-Speed Counter (VHSC) module designed for applications requiring precise pulse, frequency, and position monitoring. Operating at 24 VDC, it supports up to 1 MHz input frequency and includes one group of A/Aret, B/Bret, Z/Zret inputs and one isolated group of two 24 VDC outputs (0.5 A per output). This module integrates seamlessly into POINT I/O systems and is ideal for high-speed counting, encoder feedback, rate measurement, and motion-related applications.

Information About 1734-VHSC24
The Allen-Bradley 1734-VHSC24 acts as both a signal conditioner and a function block, processing high-speed counter signals and passing them to the POINTBus backplane for the controller. With a 1 MHz maximum input frequency, this module is suitable for use with high-resolution encoders, turbine meters, flow sensors, mechanical switches, pulse transducers, and other motion-related devices. Designed for industrial reliability, the 1734-VHSC24 includes multiple input filtering options (OFF, 10 μs, 100 μs, 1 ms, 10 ms) to ensure noise immunity and accurate counting. Outputs are rated 0.5 A at 24 VDC and isolated, allowing safe switching of control signals. Its 24-bit counting range (0 – 16,777,215) is stored internally in a 32-bit register, enabling configurable presets, rollover settings, and real-time counter operation.
Key Features:
- Very High-Speed Counter up to 1 MHz
- Supports quadrature encoder inputs
- 1 group of A/Aret, B/Bret, Z/Zret inputs
- 2 isolated 24 VDC sourcing outputs
- Modes: Counter, Encoder, Rate, PWM, Pulse Generator
- Adjustable input filtering
- Compact POINT I/O design
- DIN-rail mountable
- Ideal for motion control and high-speed feedback systems
The module mounts to a POINT I/O base (1734-TB or 1734-TBS) and is DIN-rail ready. It carries cULus and CE certifications and operates across a wide environmental range, making it reliable for demanding automation environments.
