IC200MDL644 GE VersaMax Discrete I/O Module

Module Overview

The IC200MDL644 discrete input module provides four groups of 8 discrete inputs. Each group can be configured for positive logic inputs receiving current from input devices and returning it on the common, or negative-logic inputs receiving current from the common and returning it to the input device. Input devices are connected between the input terminals and common terminals. The module supports positive and negative logic inputs. For compatibility with TTL devices, the negative logic configuration is recommended.

Module Specifications

• Points: 32 (4 groups of 8)

Configuration Parameters

The module’s basic input on/off response time is 0.25ms. For specific applications, additional filtering may be necessary to address noise spikes or switch bounce. Input filter times of 0ms, 1.0ms (default), or 7.0ms are selectable via software configuration, resulting in total response times of 0.25ms, 1.25ms, and 7.25ms respectively.
