Honeywell 621-0307 High-Speed Counter Module

The Honeywell 621-0307 High-Speed Counter Module is a specialized counter module for the IPC 621 platform. It provides two independent high-speed counting channels for pulse, encoder, and motion-related applications, supporting fast signal acquisition, programmable counting functions, and high-capacity pulse accumulation.

Counting and Input Functions

The module features two independent counter channels capable of processing high-frequency pulse signals up to 1 MHz, depending on application configuration.

Supported input signal types include:

• TTL pulse signals

• 24 VDC pulse signals

• Encoder signals

• Push-pull interfaces

Programmable preset, latch, and reset functions support position tracking, speed measurement, and pulse counting applications.

Electrical Characteristics

The module receives power directly from the IPC 621 rack backplane and operates from a 24 VDC supply. Channel-to-system isolation helps reduce the effects of electrical noise on high-speed counting signals.
