Physical Construction and Component Layout

This TSXDMZ28DTK I/O module measures 4.5 inches in height. Its width reaches 3.7 inches with a depth of 2.5 inches. The total weight comes to approximately 0.68 pounds. Manufacturers placed 142 discrete components on this compact PCB. These components include optocouplers, transistors, current limiters, and LED drivers. The board uses a robust four-layer design for signal integrity.

Input Channels and Signal Characteristics

TSXDMZ28DTK provides 16 digital input channels for field devices. Each input accepts 24V DC signals from sensors or switches. Typical input current draws only 6 milliamps at 24V DC. This low current minimizes heat generation inside the module. Response time reaches 1 millisecond for both ON and OFF transitions. Green LEDs illuminate for every active input channel. Consequently, you can monitor field device status at a quick glance.

Output Channels and Drive Capability

The I/O module delivers 12 sourcing transistor outputs for load control. Each output drives up to 0.5 amps continuously at 24V DC. Total combined output current reaches 4 amps maximum. Outputs can switch solenoids, indicator lamps, or relay coils. Short-circuit protection prevents damage from wiring faults. Amber LEDs show the status of every output channel. Optical isolation withstands 1500V AC for safe field wiring. Therefore, the TSXDMZ28DTK handles mixed I/O requirements efficiently.

Communication and Energy Storage

TSXDMZ28DTK includes one RS-485 port for Modbus networking. This port connects to HMIs, drives, or remote I/O devices. For energy storage, the module integrates three 100µF capacitors. Two additional 47µF capacitors filter high-frequency power noise. The module draws 130 milliamps from the 24V DC backplane. You will find this I/O module in TSX Micro PLC systems. For example, it suits small conveyors, packaging machines, or sorters. The unit operates reliably from 0°C to 55°C ambient.
