I/O modules

The GE 8164-4002 output module provides dependable signal transmission from the controller to field actuators and devices. This versatile module manages discrete and analog output signals for comprehensive process control. Its compact housing measures 140 mm in height, 35 mm in width, and 120 mm in depth.

Technical Specifications

Digital Output Capabilities and Load Handling

The GE 8164-4002 provides 16 digital output channels for controlling industrial actuators. Each channel delivers 24 V DC at 0.5 A to drive contactors, solenoids, and indicator lamps. Outputs use sourcing (PNP) configuration for compatibility with standard field devices. Short-circuit protection on each channel prevents damage during wiring faults or overload conditions.

Analog Outputs and Signal Precision

Four analog output channels generate 4–20 mA current signals for precise actuator positioning. These outputs connect to variable frequency drives, valve positioners, and chart recorders. Accuracy remains within ±0.25% of full scale under normal operating conditions. Each channel completes response within 10 ms for responsive process control loops.

Protection Systems and Fault Tolerance

The GE 8164-4002 includes comprehensive protection against overcurrent and short-circuit events. Outputs automatically disconnect when current exceeds 0.7 A to prevent thermal damage. The module detects open-wire conditions on analog channels and reports these faults. Such protective features ensure reliable operation and extend the service life of connected equipment.

Power Supply and Energy Efficiency

This module draws 4.2 W from the backplane power supply during normal operation. This moderate consumption reduces thermal load inside the control cabinet. Engineers can install multiple modules without exceeding the power budget of the rack. The board uses efficient driver circuits that minimize heat generation during continuous operation.

Backplane Communication and Control Interface

The GE 8164-4002 connects to the PLC backplane for rapid data exchange with the CPU. This parallel interface ensures deterministic update cycles for time-critical control tasks. The module updates outputs immediately upon receiving new command data. Status feedback travels to the processor for real-time monitoring and fault logging.

Visual Diagnostics and Status Indication

Twenty front-panel LEDs display per-channel output status and overall module health. These indicators assist technicians in identifying active outputs without opening the cabinet. A power LED confirms the presence of both logic and field supplies. Fault LEDs illuminate when the module detects overcurrent, short-circuit, or communication errors.

Installation and System Mounting

Mount the GE 8164-4002 on a standard 35 mm DIN rail using the integrated clip mechanism. Its 35 mm width preserves valuable panel space for additional I/O modules. The 24-pin removable terminal block simplifies wiring replacement and module exchange. Connect field devices using wire gauges from 0.2 to 1.5 mm² for reliable terminations.
