I/O modules

The Triconex 7400221-100 Model 2381 Pulse Input Baseplate (PI2381) is a durable module designed for industrial pulse input systems. It provides reliable connectivity and flexible integration for sensors, actuators, and I/O devices.

Robust Terminal Block Design

The PI2381 includes three types of terminal blocks: configuration, sensor, and resistor, each optimized for system performance and sensor compatibility.

• The configuration block allows selection between passive or active magnetic sensors and enables internal pull-up resistor activation.
• The sensor block connects sensors directly to the baseplate, simplifying wiring.
• The resistor block accommodates termination resistors for passive sensors and pull-up resistors for active open-collector sensors.
• Factory default settings preset configuration blocks to differential mode and sensory blocks as spares with shorted inputs.
