GE GPS2MHAP Central control module

GE Output Modules Overview

General Electric (GE) offers a wide range of output modules for various industrial automation systems. These modules are used to translate signals from the controller into the electrical signals required to drive field devices such as valves, motor starters, indicator lights, etc.

Product Detailed Description

As GE provides numerous output modules, the following is a general description. Specific features depend on the module type (e.g., discrete output, analog output, relay output) and series (e.g., RX3i, RX7i, VersaMax, etc.).

• Function:

• Receives control signals from the PLC or control system.

• Converts these signals into appropriate voltage and current levels to drive external devices.

• Provides electrical isolation to protect the control system from field device faults.

• May include diagnostic functions to indicate output status or faults.

• Features (depending on module type):

• Discrete Output Modules: Used to control on/off devices like solenoid valves, contactor coils, indicator lights. Can be transistor (sourcing or sinking), triac, or relay outputs.

• Analog Output Modules: Used to control devices requiring continuously variable signals, such as valve positioners, variable frequency drives (VFDs). Typically output voltage (e.g., 0-10V, ±10V) or current (e.g., 4-20mA).

• Relay Output Modules: Use electromechanical relays to switch loads. Suitable for both AC and DC loads and provide galvanic isolation.

Product Parameters

Due to the wide variety of models, the following are some potentially relevant parameters. Always refer to the specific GE output module model datasheet for detailed specifications:

• Output Current Capacity (per point/per module):

• Discrete: E.g., 0.5A/point, 2A/point.

• Analog: E.g., 20mA/point.

• Isolation Voltage:

• E.g., 500V AC (field side to logic side).

• Response Time:

• Discrete: E.g., microseconds to milliseconds (depending on type).

• Analog: E.g., milliseconds.
