FUNCTIONAL DESCRIPTION:

IS200TBQFH2A is a 16-channel Analog Input Termination Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The 16-Channel Analog Input Termination Module is engineered to interface field analog signals with a centralized control or monitoring system, typically within Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC). Each of the 16 channels provides an independent termination point for analog inputs such as 4–20 mA current loops, 0–10 VDC signals, or thermocouples and RTDs, depending on the signal conditioning design.

The module offers high-density connectivity and ensures signal integrity through optimized PCB layout and minimized crosstalk. Designed for robust industrial environments, it incorporates protection components such as transient voltage suppressors, current-limiting resistors, and isolation circuitry to safeguard connected systems against electrical noise, surges, or grounding inconsistencies.

Channel identification and test points are marked, allowing for rapid diagnostics and streamlined maintenance. Signal conditioning elements (if integrated) may include filtering, linearization, and cold-junction compensation.

INSTALLATION:

The 16-Channel Analog Input Termination Module is designed for quick and secure installation within industrial control cabinets. It should be mounted on a standard DIN rail or securely fastened to a backplate, ensuring sufficient clearance for ventilation and cable management. Field analog signals—such as 4–20 mA loops, voltage signals, or sensor outputs—must be connected to the respective input terminals using shielded twisted-pair cables to minimize electrical noise and interference. Proper termination practices, including correct polarity and grounding, are essential to ensure signal integrity. The shield of the cable should be connected to a designated ground point to prevent EMI-related issues. Once the field wiring is complete, the module is interfaced with the analog input card of the DCS or PLC using a multi-pin connector or ribbon cable, following manufacturer-recommended cable routing guidelines to avoid signal coupling from power lines or other high-voltage sources. Before system startup, a thorough inspection and verification should be performed using a multimeter or signal simulator to ensure continuity, correct wiring, and proper operation of all input channels.

OPERATION:

The 16-Channel Analog Input Termination Module passively facilitates the transmission of analog signals from field instruments to the analog input interface of the host control system.

The module ensures:

• Signal Isolation (if designed with isolation barriers): preventing ground loops and electrical noise interference.
• High Signal Fidelity: maintaining accuracy across all 16 channels without signal degradation.
• Real-Time Data Acquisition: enabling the control system to read field measurements such as temperature, pressure, level, or flow.
• Maintenance personnel can use the integrated test points for live signal checks during operation without disturbing the control logic. The module is designed for continuous 24/7 operation in harsh industrial conditions with minimal need for recalibration or downtime.

FREQUENTLY ASKED QUESTIONS:

What is the function of a 16-channel analog input termination module?

This module provides a structured interface for connecting up to 16 analog input signals from field devices (such as transmitters or sensors) to a control system like a DCS or PLC. It facilitates signal organization, conditioning (if applicable), and wiring integrity.

What types of analog signals does this module support?

It typically supports industry-standard analog signals such as 4–20 mA, 0–10 VDC, 1–5 VDC, and in some configurations, thermocouple or RTD inputs, depending on the design.

What is the recommended wiring specification?

Use shielded twisted-pair (STP) cables rated for low-level analog signals (typically 22–24 AWG). The shield should be grounded at the control panel side to minimize common-mode noise. Cable routing must observe separation from power lines per IEEE 518 guidelines.
