GE Industrial Control Interface Characteristics
The IS230SNRTH2A/IS200SRTDH2ACB functions as a field-side relay interface within the Mark VI Speedtronic hardware architecture. The board provides physical connection and relay switching functions between control circuits and external electrical devices.
In GE industrial control systems, terminal hardware must maintain defined electrical interfaces between controller-side circuits and field wiring. Therefore, installation quality directly affects signal continuity, relay operation, and maintenance access. The terminal board should remain compatible with the associated system hardware configuration and approved wiring arrangement.
The relay contacts are rated for 3 A @ 24 VDC. Field circuit loading should remain within the specified contact rating. In addition, wiring separation between switching circuits and sensitive signal conductors helps reduce electrical interference.
Frequently Asked Questions
Q: What is the primary function of the IS230SNRTH2A/IS200SRTDH2ACB?
A: The board functions as a Terminal Relay Board for the GE Mark VI Speedtronic series. It provides relay contact interfaces and physical termination points for connected electrical circuits.
Q: What logic power does the IS230SNRTH2A/IS200SRTDH2ACB require?
A: The specified logic power is 24 VDC. The power source polarity and wiring should be verified before system energization.
Q: Can the relay contacts directly switch loads above 3 A?
A: No. The specified contact rating is 3 A @ 24 VDC. External interposing devices should be considered when the connected load exceeds the specified contact capability.
Field Installation Guidelines
- Install the board only in the designated GE Mark VI system location or approved hardware assembly.
- Verify the complete model number IS230SNRTH2A/IS200SRTDH2ACB and associated IS200SRTDH2A base model before installation.
- Isolate system power before connecting or removing field wiring.
- Confirm 24 VDC polarity before applying logic power to the board.
- Keep relay output wiring separated from low-level signal circuits where practical.
- Route field conductors to minimize mechanical stress on terminal connections.
- Tighten terminal connections according to the applicable GE installation documentation.
- Inspect wiring insulation and shielding before system energization.
- Maintain the specified environmental limits of -30 deg C to +70 deg C during operation.
- Prevent condensation within the installation enclosure and maintain humidity within the specified non-condensing range.
- Verify connected load current against the 3 A @ 24 VDC contact rating before placing the circuit into service.
