ODOT CT-122F digital I/O module 16 PNP inputs 24 VDC

The ODOT CT-122F digital I/O module is a remote input module with 16 digital PNP channels at 24 VDC, designed for the ODOT Series C remote I/O system. It is ideal for acquiring digital signals from field devices in industrial automation, supervision and distributed control applications.

Used together with a Series C network adapter and extension I/O modules, the CT-122F collects digital output signals from field equipment with dry contact or active output and is compatible with 2‑wire and 3‑wire digital sensors. Each channel is equipped with its own status LED, providing instant visual diagnostics and simplifying commissioning and maintenance activities.

The module uses optoelectronic isolation between field inputs and the internal bus, ensuring high immunity to electrical noise and protecting the system electronics. It supports advanced features such as input signal hold with configurable time, digital input filtering and 32‑bit counting up to 200 Hz on each channel, with freely configurable counting mode and direction.

• 16 digital PNP input channels at 24 VDC with individual LED status indicators.
• Compatible with 2‑wire and 3‑wire digital sensors, dry contact or active output.
• 3 kVrms optoelectronic isolation between field I/O and internal bus for improved protection.
• Configurable digital filter, input hold and 32‑bit counter up to 200 Hz per channel.
• Field power 24 VDC (19.2–28.8 VDC), DIN rail 35 mm mounting, IP20 protection class.
• Perfect for remote I/O systems, compact control panels and digital signal acquisition in SCADA and PLC applications.
