Overview

WEA13-13 2508-21001 is a GE legacy 8-channel isolated analog input module, widely deployed in mission-critical distributed control systems and compatible with GE VMIC VMEbus rack systems. This card converts field analog sensor signals into digital data for the host VME single-board computer, serving as the primary field signal acquisition interface for process plants.

It supports multiple configurable input signal types including 4–20mA current, 0–10VDC voltage, RTD and thermocouple inputs, making it flexible for temperature, pressure, flow and level transmitters. Built-in channel-to-channel isolation suppresses common-mode noise and ground loop interference, which is essential for heavy industrial environments such as power generation.

This module is designed to work with the VMIVME series VME SBC family, including VMIVME‑7750, VMIVME‑7698, VMIVME‑7697‑167 and VMIVME‑7658. WEA13-13 2508-21001 is end-of-life and no longer manufactured by GE. We supply fully tested surplus and refurbished units for plant maintenance and drop-in spare replacement.

WEA13-13 2508-21001

Key Features

• 8 Configurable Analog Input Channels: Multi-range field signal acquisition for transmitters, thermocouples and RTD sensors
• Channel Isolation Design: Channel-to-channel and bus isolation to eliminate ground loops and EMI interference
• 14-bit High Resolution A/D Conversion: Delivers precise measurement for critical process variables
• Multi-Signal Compatibility: Supports 4–20 mA, 0–10 VDC, thermocouple and RTD inputs
• Wide Operating Temperature: Stable operation under extreme industrial temperature conditions
• Standard Rack Mount Form Factor: Designed for DCS backplane installation, hot-swap capable for many rack configurations
• Low Power Consumption: Typical 5W power draw, reduces thermal load inside control cabinets
• Built-in Diagnostic Circuits: Open wire detection, over-range alarm and channel fault reporting to host controller
• Compatible with VMIC VME SBC Rack: Works with VMIVME-7697-167, VMIVME-7698, VMIVME-7750 and other VME CPU boards

WEA13-13 2508-21001 Position in VME Rack System

The WEA13-13 2508-21001 is an analog field I/O card. It pairs with VMIVME SBC host boards:

• VMIVME‑7697‑167, VMIVME‑7698, VMIVME‑7750 (VME CPU host)
• VMIVME‑7452 / VMIVME‑7455 (storage carriers for OS and firmware) The analog module collects field sensor data and transmits digital values to the VME SBC for control logic, alarming and data logging.

Why Choose WEA13-13 2508-21001

For legacy GE DCS and VMIC VME control racks, the WEA13-13 2508-21001 is a common spare analog input card. Channel isolation and multi-signal support make it very versatile for different field transmitters.

Replacing a failed unit with tested refurbished hardware avoids full system redesign and reduces plant downtime.
