Product Description

CT-122F 16 channels digital input/0VDC/Source type

Product Characteristic

The CT-122F is a 16-channel digital input module from Sichuan ODOT Automation System Co., Ltd., designed for source-type (sourcing) wiring with 0VDC reference, where a low-level input signal is valid. It accepts signals from dry contacts, active outputs, and 2-/3-wire digital sensors. Each channel features optocoupler isolation between field inputs and the internal bus, an individual LED indicator, and configurable input filtering and signal holding time. With an optional counting sub-module, every channel supports an independent 32-bit counter (<200 Hz), with user-defined counting mode, direction, and byte transmission sequence—enabling precise event monitoring in demanding industrial environments.

FQA

Q：What is the input type and logic level definition of the CT-122F module?

A：The CT-122F is a 16-channel digital input module with source-type wiring. It uses 0V as the valid input signal, where a low logic level is active—ideal for NPN sensors or dry contact signal acquisition.

Q：Does the CT-122F support counting functionality? What are its performance specs?

A：Yes, with an optional counting sub-module, each channel features a 32-bit counter supporting up to 200 Hz counting frequency, with independently configurable counting mode, direction, and byte transmission sequence.

Q：What design features ensure electrical isolation and signal reliability in the CT-122F?

A：The module uses optocouplers for electrical isolation between the internal bus and field inputs. It also offers configurable input filtering, signal holding time, and 16 independent LED indicators—one per channel—to ensure stable and reliable operation in demanding industrial environments.
