Product Description

The 7DM438.72 I/O Module offers a flexible and reliable input/output solution for industrial automation and control applications. With 8 digital inputs and 8 transistor outputs packed into its compact design, it provides versatility for a wide range of monitoring and control tasks. This module features 24 VDC digital inputs with fast 1 ms response times, allowing quick detection of signals from sensors or switches. The inputs can be configured for either sink or source wiring. Compatibility with both AC and DC inputs provides flexibility for interfacing with various field devices.

On the output side, 8 protected transistor outputs can switch loads at currents up to 0.5 A per channel. The 24 VDC nominal voltage matches common actuator and PLC input voltages. Built-in short circuit and overload protection give added reliability. Whether used for basic on/off control, DC motor driving, or activating indicators and annunciators, the transistor outputs offer the convenience of sole power supply requirement. This simplifies wiring and installation. The outputs high switching frequency also suits use for pulse width modulation and other applications needing fast cycling.

Housed in a compact housing that occupies minimal space on the DIN rail, the 7DM438.72 module maintains a slim 3.0 x 3.0 x 5.0 footprint. Its high-density packing of I/O in this size makes it perfect for small controls cabinets and hardware with limited space. Conformal coating on the circuit board resists moisture, dust, chemicals, and temperature extremes frequently encountered in industrial settings. This ruggedization allows reliable operation in demanding environments. Diagrammatic labels silkscreened onto the housing provide clear terminal identification.
