Schneider MDL 67 PLC Module | 8 Inputs 6 Relay Outputs 2A

The MDL 67 functions as a mixed input/output module for Schneider PLC systems. This unit combines digital inputs and relay outputs in one compact package. Its rectangular frame measures 112 millimeters in width. The module height reaches 100 millimeters exactly. Depth stays at 75 millimeters. You will find this unit weighs approximately 0.38 kilograms. Therefore, installation requires only a standard DIN rail clip. Two removable terminal blocks handle all field wiring connections.

Physical Layout and Connectors

Each terminal block accepts wires up to 16 AWG gauge. A green LED indicates power present on the module. Individual LEDs show status for each input and output channel. Four mounting tabs secure the unit to TS35 DIN rails. You can remove the terminal blocks without disconnecting the module from the rack.

Internal Design and Energy Storage

The MDL 67 contains exactly 156 discrete components onboard. A 330 microfarad capacitor bank filters the internal logic power supply. Eight optocouplers isolate the input channels from the backplane logic. Six mechanical relays perform the output switching functions. Each relay includes a built-in snubber for inductive load protection. The module also stores configuration data in onboard EEPROM memory.

Operational Performance

This PLC module reads eight digital inputs from pushbuttons or sensors. It switches six relay outputs to control motors or solenoids. Moreover, the unit handles both AC and DC output loads up to 2 amperes. You can connect incandescent lamps, contactors, or small heaters directly. The module reports input state changes within 5 milliseconds. Eight green LEDs show real-time input status at a glance. Six yellow LEDs indicate which relay outputs are currently active. Consequently, you achieve efficient mixed I/O control for small machines. Schneider designed this module for compact automation applications. Its plastic housing meets IP20 protection standards for control cabinets.

In summary, the MDL 67 delivers versatile mixed I/O capability. Use this module for conveyor control or packaging equipment. It reduces component count by integrating both input and output functions. Order this PLC module for your Schneider automation system.
