Physical Characteristics and Installation

This pulse counter module weighs approximately 0.38 kg for standard rack mounting. Its dimensions measure 160 mm x 120 mm x 45 mm for distributed I/O chassis. First, slide the 200-IP2 into a free slot in your I/O rack. Then, connect your pulse sources to the screw terminals. Finally, configure the counter modes through your control software. LED indicators show power status and pulse activity per channel.

Input Specifications and Counting Modes

The 200-IP2 provides 2 independent counter channels for flexible measurement. Each channel accepts input frequencies up to 50 kHz for high-speed applications. You can connect either RS-422 differential or single-ended signals. The module offers four counting modes for various needs. Up mode counts positive pulses only. Down mode decrements from a preset value. Up/down mode uses two signals for direction. Quadrature mode decodes encoder A/B signals for position tracking.

Resolution and Isolation

A 32-bit counter resolution stores up to 4.2 billion counts per channel. This large range suits long-term totalizing without overflow. 1500V AC isolation separates each counter channel from the backplane bus. Consequently, this design protects the controller from electrical noise. The 200-IP2 requires both 5V DC logic power and 24V DC field power for operation.
