Kontron / PEP PB-DIO3 Digital I/O ModPack

The Kontron / PEP PB-DIO3 Digital I/O ModPack is a legacy industrial module delivering 10 opto-isolated digital input and 10 opto-isolated digital output channels. Built around the Motorola 68230 Programmable Integrated Timer, the PB-DIO3 provides reliable signal isolation and precise timing control in demanding environments. The module operates across an extended temperature range from −40°C to +85°C and integrates directly with PEP VMOD-2 and CXM-IMOD carrier boards under OS9 and VxWorks operating systems. ## Technical Specifications Digital I/O Architecture • 10 digital output channels: 24V DC, 100 mA maximum per channel, opto-isolated, configurable common GND or Vcc • 10 digital input channels: 24V DC, 5 mA typical, opto-isolated, common GND configuration • 24-bit timer running at 8 MHz • External timer input (TIN) accessible on module • 2 input and 2 output handshake lines derived from the 68230 controller Power & Environment • Supply: +5V DC (±5%), 500 mA typical • Operating temperature: −40°C to +85°C ## Key Features Opto-isolation on all digital channels eliminates ground loop issues and protects downstream logic from transient faults. The integrated 24-bit timer at 8 MHz enables precise timing and event sequencing without external timing circuits. Flexible output configuration (common GND or Vcc) adapts to diverse industrial control schemes. Handshake line support streamlines protocol-based I/O coordination. ## Typical Applications Industrial process control, factory automation, supervisory relay logic, sensor/actuator interfacing, timing-critical event logging, and legacy system modernization where OS9 or VxWorks platforms remain in service. ## Compatibility & Integration The PB-DIO3 mounts on PEP VMOD-2 and CXM-IMOD carrier boards and ships with driver support for both OS9 and VxWorks, ensuring straightforward integration into established control architectures.
