I/O modules

Product Overview

This positive logic output module delivers sixteen discrete outputs for controlling DC loads in automation systems. It interfaces seamlessly with the RX3i or Series 90-30 programmable controllers. The IC694MDL753 provides high-speed switching for actuators, indicators, and relay coils. Users can connect this module directly to sourcing-type field devices without additional interface components.

Technical Specifications

The IC694MDL753 measures 12.5 cm in height and 11.4 cm in depth with standard PACSystems dimensions. It weighs approximately 0.35 kg, including all internal components and terminal hardware. This module draws 150 mA from the +5 VDC backplane supply during normal operation. It requires an external 24 VDC power source for the output field circuits. The module features sixteen output channels with a maximum current rating of 0.5 A per point. The total output current limit across all channels reaches 4 A. Each output includes built-in overcurrent protection and thermal shutdown features. The output voltage drop measures less than 0.3 V at rated current for efficient operation. This module responds to logic signals within 1 ms for time-critical control applications. It provides optical isolation of 1500 VAC between backplane and field circuits.

Output Configuration and Protection

This module employs positive logic where a logic “1” turns the output on. It accepts signals from the CPU and drives loads connected to the +24 VDC supply. The IC694MDL654 includes individual LED indicators for every output channel status. Its short-circuit protection prevents damage from wiring faults or overload conditions. Each output also features a flyback diode for inductive load suppression.

Physical and Electrical Parameters

Installation and Wiring Procedures

Mount the IC694MDL753 into any available slot within the RX3i or Series 90-30 rack. Secure the module using the retaining screws positioned at the top and bottom. Connect the external 24 VDC supply to the designated field power terminals. Wire each load from the output terminal through the load device to the common return. The CPU automatically assigns output addresses upon system power-up. Verify the positive logic configuration matches your application requirements.

Typical Applications

This output module controls solenoid valves, indicator lamps, and solid-state relays. It drives motor contactors, alarm buzzers, and machine vision system lights. The IC694MDL753 serves packaging equipment, assembly lines, and test fixtures. Its sixteen-point density suits applications requiring numerous discrete outputs.
