IS410SRLYS2A IS400SRLYS2ABB Relay contact output terminal board

Both GE IS410SRLYS2A and IS400SRLYS2ABB are 12-channel single-channel relay contact output terminal boards (SRLY, simplex configuration) of the Mark VIeS series, compatible with YDOA I/O modules.

The core is used for on-site wiring and interface conversion of Form -C relay output for the Mark VIeS system, which is commonly seen in industrial control scenarios such as thermal power and gas turbines.

The following is the core information and comparison:

The adapter module is matched with the IS420. YDOAS1B and other YDOA discrete output modules on the left

Core positioning: Standard mass production type, engineering customization/substitution type, used for project replacement or batch projects

Core function

Output interface: It provides on-site terminal blocks for 12-channel Form -C relay output, which are compatible with the switch control signal output of actuators such as contactors, valves, and indicator lights.

System adaptation: By communicating with the YDOA I/O module through the on-board ID chip, it supports system diagnosis and module recognition, ensuring reliable signal interaction.

Engineering Compatibility: As an engineering derivative model, IS400SRLYS2ABB meets the procurement specifications of specific projects or the replacement requirements of standard models. Its electrical performance is consistent with that of the standard model.

Easy maintenance: High-density European-style terminal blocks with clear markings facilitate quick wiring and fault detection.

Typical applications

It is compatible with the control systems of Mark VIeS gas turbines, thermal power plants, etc., and is used for the transfer of strong electrical contact signals such as equipment start-stop control, alarm output, valve switch instructions, etc., such as the control signal output of equipment like drive motor contactors, fuel gate valves, ventilation system dampers, etc.
