Core Technical Specifications

The 140DDO35310C discrete output module provides thirty-two independent sinking outputs for industrial control applications. This unit measures 140 millimeters in height, 40 millimeters in width, and 140 millimeters in depth, with a total weight of approximately 0.38 kilograms for convenient handling during installation. Each output channel delivers a maximum load current of 500 milliamperes at 24 volts DC. The module includes built-in short-circuit protection and thermal shutdown for each individual output point.

Output Performance and Diagnostics

This module scans and updates all output states within a single 1-millisecond scan cycle. It features individual channel status indicators on the front panel for rapid fault identification. The 140DDO35310C incorporates open-wire detection to sense broken field wiring immediately. It also provides over-temperature protection that shuts down affected channels automatically. The module reports diagnostic data back to the processor through a dedicated status word.

Physical Layout and Installation

You can mount the module directly onto any standard backplane using its single-slot form factor. Its front face includes a 40-pin connector for all field output wiring terminations. The module occupies minimal panel space due to its narrow 40-millimeter width design. LED indicators display power-on, output activation, and fault conditions for each channel group. The unit’s robust housing protects internal components against dust and accidental contact.

Memory and Configuration Resources

The 140DDO35310C stores all output state data in 2 kilobytes of internal dual-port RAM. It retains configuration settings using 1 kilobyte of non-volatile EEPROM memory. The module maps each output to a specific register address within the processor’s I/O table. It supports both sinking and sourcing wiring configurations through external jumper settings. The unit automatically resets all outputs to a safe state upon detecting a communication loss.

Power Supply and Environmental Tolerance

The module draws a maximum supply current of 250 milliamperes from a 5-volt DC backplane bus. It requires an additional external 24-volt DC supply to power the field output circuits. The unit operates reliably across a temperature range from 0 to 60 degrees Celsius. It withstands relative humidity levels between 5% and 95% without condensation. The module complies with IEC 61131-2 standards for industrial control equipment safety. Its circuitry includes optical isolation between the logic side and each output channel.

Integration and Operational Flexibility

You can enable or disable individual output channels through simple software configuration commands. The module supports both continuous and pulsed output modes for various actuator types. It provides programmable output delays ranging from 0 to 10 milliseconds per channel. The unit also allows you to configure fail-safe states for each output independently. This flexibility simplifies integration with diverse field devices like solenoids, relays, and indicator lights.
