2MLI-D22A Honeywell MasterLogic-200 Digital Input Module

The 2MLI-D22A is a 16-point digital input module manufactured by Honeywell for the MasterLogic-200 PLC platform. Operating on a 24 VDC rated input voltage, it interfaces field discrete switches and sensors to the system controller, supporting flexible current sink or current source wiring configurations.

Field Signal Interface

The module accommodates 16 discrete channels designed to accept 24 VDC logic signals from field devices. Because the input channels support both sink and source circuitry, maintenance personnel can configure the module to match either PNP or NPN field transmitter outputs on the same chassis.

Environmental Operating Limits

Designed for cabinet mounting in standard control environments, the unit operates in ambient temperatures ranging from 0 to 55 deg C and stores between -25 and +70 deg C. It tolerates relative humidity from 5 to 95 percent without condensation and is rated for operation at altitudes below 2000 m.
