ALSTOM

Product Background

LC105A‑1 is Eurocard‑format relay output slot‑in board for ALSTOM ALSPA‑P320 / T2000 DCS control system, not belonging to GEM80 platform. It is mounted inside P320 / T2000 sub‑rack and communicates with CPU via back‑plane bus. This board integrates 16‑channel relay outputs for field control‑signal transmission.

OEM production discontinued (EOL). Available stocks are mainly used/refurbished spare parts for legacy thermal & gas‑fired power‑plant P320/T2000 system maintenance replacement.

Model Breakdown

1. ALSTOM: Brand, France
2. LC105A‑1: Complete hardware model; suffix “‑1” denotes hardware revision
3. PCB: Printed circuit board hardware carrier; Control board: control circuit board

Main Functions

1. 16‑channel relay discrete output Sixteen built‑in relay output channels receive logic commands from CPU, provide dry‑contact signals to drive field actuators such as interposing relays, solenoid valves, indicator lamps and trip circuits, to realize equipment start‑stop, valve switching and protection‑trip output.More products: www.plcva.com
2. Back‑plane bus data interaction Communicate with CPU processor board over P320/T2000 back‑plane bus, receive control logic commands and upload board working status.
3. On‑board self‑test & status indication On‑board LED indicators show per‑channel output status, power supply and fault alarm information for convenient on‑site troubleshooting.
4. Galvanic isolation for relay loops Relay contacts provide electrical isolation; field‑side faults will not easily damage internal control‑system circuits. Designed for heavy‑EMI power‑plant cabinet environment.
5. Battery‑backed RAM Battery‑backed RAM preserves critical status data upon power loss. Wide‑temperature industrial design supports long‑term continuous generator‑unit operation.

Note: This board is dedicated for ALSPA‑P320 / T2000 platform only, not compatible with GEM80 or CE2000 systems. It cannot operate standalone and must work with CPU module inside matched sub‑rack.

Applications

1. Thermal / gas‑fired power‑plant ALSPA P320 / T2000 DCS control system (primary application) Mounted inside P320 / T2000 controller sub‑rack. It outputs discrete control signals for turbine, boiler auxiliary equipment, valve and protection‑trip logic handling. Classified as critical field‑replaceable I/O spare part for power‑plant DCS system.
2. Applied exclusively for maintenance replacement of legacy power‑generation units; not specified for new‑project design.
3. Incompatible with GEM80, CE2000 and other third‑party DCS hardware platforms.
