GE IS200TPROH1B IS200TPROH1BCB Termination Board

The GE IS200TPROH1B IS200TPROH1BCB Protective Termination Board connects safety-related field devices to the protection system. You will find this board essential for surge suppression and signal conditioning. Its robust design protects downstream electronics from voltage transients.

Dimensions, Weight, and Mechanical Layout

This protective termination board measures 20.5 cm in length and 16.0 cm in width. Its height reaches 4.2 cm including all surge suppression components. The total weight stands at 0.71 kilograms for heavy-duty DIN-rail mounting. A flame-retardant UL 94V-0 PCB provides excellent fire safety protection.

Terminal Interfaces and Component Count

The GE IS200TPROH1B IS200TPROH1BCB Protective Termination Board offers twenty-four independent screw terminal connections. Each terminal includes a gas discharge tube for overvoltage protection. You also receive six dedicated shield terminals for earth grounding. In total, this board contains 187 individual electronic components. These include 24 gas discharge tubes, 36 transient voltage suppressors, and 72 current-limiting resistors.

Surge Protection and Filtering Features

Each signal path incorporates three-stage surge suppression for maximum safety. The first stage uses gas discharge tubes for high-energy protection. The second stage employs transient voltage suppressors for fast clamping action. The third stage adds series resistors for current limiting. Consequently, the board withstands 6 kV surge pulses per IEC 61000-4-5.

Environmental Limits and Wiring Specifications

Therefore, the operating temperature ranges from -40°C to +75°C. Storage temperatures extend from -55°C to +85°C without degradation. Maximum terminal current rating reaches 3 amperes per connection. Voltage rating stands at 250V AC or DC for normal operation.

Connectors, Cabling, and Additional Features

Two 50-pin ribbon cable headers connect to turbine protection boards. A single ground bus bar provides low-impedance earth connection. For similar static trip system protection termination, see the RMS-TSG-TZ-C model from the same manufacturer. However, this protective termination board specializes in safety-related signal conditioning exclusively. Mean time between failures (MTBF) exceeds 280,000 hours due to passive surge protection design.
