CONTEC PO-32L(PC)V – 32-Channel Isolated Digital Output Module | PC Bus I/O Platform
Engineering Background
The PO-32L(PC)V is a PC bus digital output expansion card developed by CONTEC Co., Ltd. (Japan), a globally recognized leader in industrial I/O hardware. Designed for demanding factory automation and process control environments, this module delivers 32 channels of photocoupler-isolated digital output via a standard PC bus interface, enabling reliable signal transmission to external actuators, relays, solenoids, and indicator systems.
Product Positioning
Targeted at control system integrators, OEM machine builders, and industrial PC platform developers, the PO-32L(PC)V bridges the gap between PC-based controllers and field-level output devices. Its compact form factor, robust isolation architecture, and broad OS driver support make it the preferred choice for engineers requiring deterministic, high-density digital output in space-constrained panel PCs and industrial workstations.

Engineering Advantages
- Full 32-Channel Isolation: Each output channel is individually photocoupler-isolated, eliminating ground loops and protecting the host PC from field-side voltage transients up to the rated isolation level.
- High-Density Output: 32 channels on a single PC bus card minimizes slot consumption and reduces system BOM cost versus multi-card solutions.
- Open Collector Architecture: NPN open-collector outputs are compatible with a wide range of PLC input modules, relay coils, and indicator lamps without additional signal conditioning.
- CONTEC API Driver Ecosystem: Unified C/C++, Visual Basic, and LabVIEW driver libraries accelerate application development and reduce integration risk.
- Industrial-Grade Reliability: Designed and manufactured in Japan under CONTEC’s ISO 9001-certified quality management system, with MTBF data available on request.
System Architecture & Signal Flow
The PO-32L(PC)V maps 32 output bits across four 8-bit output ports accessible via PC bus I/O address space. The host CPU writes logic-level data to the card’s onboard latch registers; each latch output drives the LED side of a dedicated photocoupler. The transistor side of each photocoupler switches the external load circuit (12–24 V DC, max. 100 mA per channel) in open-collector configuration. External power is supplied via the field-side connector, maintaining complete galvanic isolation between the PC bus domain and the field wiring domain.

Technical FAQ
Q: Is the PO-32L(PC)V compatible with modern Windows 10/11 systems?
A: CONTEC provides driver packages for Windows 10 and Windows 11 (32/64-bit). Please confirm the specific driver version with our team prior to ordering if OS compatibility is critical to your application.
Q: Can I use this card with a PCI or PCIe bus system?
A: The PO-32L(PC)V is designed for the legacy PC (ISA) bus. For PCI or PCIe systems, CONTEC offers equivalent models in the PO-32L(PCI) and PO-32L(PCIe) series. Contact us for cross-reference assistance.
Q: What is the maximum switching frequency per channel?
A: The output switching speed is limited by the photocoupler response time and the external load inductance. For relay coil loads, typical switching rates up to 10 Hz are reliable; for resistive/LED loads, higher rates are achievable. Consult the CONTEC datasheet for detailed timing diagrams.
Q: Do you provide the original CONTEC datasheet and user manual?
A: Yes. The official CONTEC PO-32L(PC)V hardware manual and API reference are available upon request. Contact support@konmask.com.
Q: Is volume pricing available?
A: Yes. Tiered pricing is available for orders of 5+ units. Submit your quantity requirement to support@konmask.com for a volume quotation.
