CT 1218 Digital Input 8DI 24VDC PNP

The CT-1218 is an 8-channel digital input module from Sichuan ODOT Automation System Co., Ltd., a provider of reliable industrial I/O Solutions for global markets. Designed for 24VDC PNP/sink-type inputs, it accepts signals from dry contacts, active outputs, or 2-/3-wire digital sensors. Each channel features optical isolation between field inputs and the internal bus, an LED status indicator, and configurable signal filtering. The module supports input signal holding with adjustable hold time and includes a built-in 32-bit counter per channel (counting frequency <200 Hz) when used with a counting sub-module. Users can independently set counting mode, direction, filter time, and counter byte transmission order for each channel.
