The GE IS230TDBTH6A(IS200TDBTH6ABC) is a powerful Discrete Input/Output Terminal Board in the Mark VI series, designed for TMR systems with DIN-rail or flat mounting. It accepts 24 group-isolated contact inputs (nominal 125V DC) and features 12 Form-C relays, expandable via an optional WROBH1 board. Equipped with 49 metal oxide varistors (MOVs) and input filters, it suppresses surges and high-frequency noise, ensuring signal integrity in harsh industrial environments.
Compatible with Mark VI systems, it connects to three PDIO I/O packs via D-type connectors, communicating with controllers over Ethernet each pack linked to R, S, or dual controllers. Installation involves mounting on a sheet metal carrier with 12-24 AWG wiring to two 48-terminal blocks (TB1 for relays, TB2 for inputs). It lacks hardware jumpers, while the WROBH1 option uses 6 jumpers to control relay power.
Key Features
Input/Output Capacity: 24 group-isolated contact inputs (125V DC) and 12 Form-C relays, with optional expansion via WROBH1.
Robust Protection: 49 MOVs and input filters guard against surges and noise, critical for industrial reliability.
TMR Compatibility: Integrates with three PDIO packs for Ethernet-based communication with TMR controllers, ensuring redundancy.
Flexible Mounting: DIN-rail or cabinet-mountable via sheet metal carrier, with pluggable Euro-style terminal blocks (TB1/TB2) for organized wiring.
Simplified Configuration: No hardware jumpers; optional WROBH1 board uses 6 jumpers to enable/disable relay power, adapting to dry contact needs.
Diagnostics: Monitors relay contacts and fuse status with WROBH, providing feedback to PDIO packs for efficient troubleshooting.
Ideal for industrial environments requiring reliable discrete signal management, particularly in turbine control systems and other critical applications where robust signal processing is essential.
