GE IS230TRLYH1B Relay Output Terminal Board

The GE IS230TRLYH1B is a Relay Output Terminal Board designed for the Mark VIe Control System series.
It serves as an interface between the control logic and external field devices by converting digital signals into relay outputs.
This module is widely used in power generation, turbine control, and critical process automation systems, ensuring reliable signal transmission and equipment protection.

Technical & Functional Q&A

Q1: How many relay outputs does the IS230TRLYH1B have?

A1: The module features 12 relay channels, each independently isolated, providing flexible control for multiple field devices.

Q2: What type of relay contacts are used?

A2: Each channel uses a Form-C (SPDT) contact, capable of handling typical loads of 5A at 125VDC or 250VAC.

Q3: What power supply options are supported?

A3: The module supports 24 VDC, 115/230 VAC, and 125 VDC, allowing integration with different control system configurations.

Q4: How does the module interface with the Mark VIe controller?

A4: Digital control signals are sent via I/O cables to the module, which activates the corresponding relay outputs. Each relay can drive either dry contact loads or coil-driven devices.

Q5: What protection features are included?

A5: Onboard fuses and surge suppression circuits protect the module and connected equipment from overcurrent and voltage spikes.

Q6: How is the module installed?

A6: It can be mounted on a DIN rail or panel, with plug-in connectors simplifying installation and maintenance. LED indicators provide visual status for each relay channel.

Q7: How does the module perform in industrial environments?

A7: It is designed to minimize electrical noise and transient effects, ensuring stable operation in harsh industrial conditions with operating temperatures from -30°C to +65°C.
