More Information

Overview Manuals Specifications Use Cases Diagnostics Safety

Features:

  • Multi-signal integration supporting current measurement, temperature sensing, and synchronization detection within a single board.
  • High electrical protection through signal isolation up to 1500 V rms for improved system reliability.
  • Wide environmental tolerance with operation from -40°C to +75°C and natural convection cooling.
General Electric IS200TPROH1BBB is intended for industrial systems that require reliable field signal termination and distribution. By supporting both analog current signals and thermocouple inputs, the board helps consolidate process monitoring functions within a compact rack-mounted architecture. The combination of multiple input types simplifies signal management in complex control environments.

A key advantage of IS200TPROH1BBB is its ability to accommodate diverse operating requirements. The board processes speed-related signals from 2 Hz to 20 kHz while also supporting synchronization detection up to 115 V rms AC. This flexibility makes it suitable for applications where multiple measurement and monitoring functions must coexist within the same control platform.

Industrial facilities often require equipment capable of operating under challenging environmental conditions. IS200TPROH1BBB addresses these requirements with a broad operating temperature range, high humidity tolerance, and maintenance-friendly natural air cooling. Combined with support for larger field wiring sizes and a 28 V DC operating supply, the board provides dependable performance for long-term industrial service.

The IS200TPROH1BBB General Electric Protective Termination Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
General Electric IS200TPROH1BBB serves as a protective termination board that manages various field connections and signal inputs for industrial automation applications. The board accommodates three 4–20 mA current input channels and nine thermocouple temperature input channels, allowing accurate collection of process measurements from multiple sources.

Designed for dependable signal handling, IS200TPROH1BBB supports synchronization detection up to 115 V rms AC and operates across a speed frequency range from 2 Hz to 20 kHz. A maximum signal isolation rating of 1500 V rms helps protect connected equipment and contributes to stable signal transmission in electrically demanding installations.

IS200TPROH1BBB operates from a 28 V DC supply and is suitable for installation in challenging industrial environments. The board supports wiring up to #12 AWG (3.0 mm²) conductors and uses convection-based natural air cooling in rack-mounted systems. With an operating temperature range of -40°C to +75°C, storage capability from -40°C to +85°C, and humidity tolerance of 5% to 95% RH non-condensing, IS200TPROH1BBB is well suited for long-term operation in process control and power generation facilities.
