Siemens6FX1122-8BD01Digital Output Module 32 Outputs 24 V DC Sinumerik CNC Rack Card

Product Description

What this part is:

Siemens 6FX1122-8BD01 digital output module for Sinumerik machine-tool CNC controls. Manufacturer: Siemens. Part Number: 6FX1122-8BD01. Siemens board number: 570 228 9104.01. Product Type: digital output module (printed circuit board). Outputs: 32. Signal Type: digital, 24 V DC. Supply Voltage: 24 V DC. Controller Platform: Sinumerik 810, 820, 850 and 880. Mounting Type: plug-in card, seated in a Sinumerik control rack. Item Weight: 1.20 kg (2.65 lb). Manufacturer Status: discontinued.

Decoding the designation:

6FX — the Siemens order-number group for Sinumerik CNC control electronics and machine-tool interface hardware.

1122 — the module family within that group, covering the rack-mounted digital input and output cards.

8BD01 — the execution code, fixing this card as the 32-point digital output version.

570 228 9104.01 — the internal Siemens board and revision number printed on the PCB, used to match a board to a rack slot when the order number has worn off the label.

What these specs mean in practice:

Outputs: 32. One card covers a full block of machine-side actuators — solenoid valves, contactor coils, indicator lamps, relay interfaces — from a single rack slot.

Supply Voltage: 24 V DC. The output stage is driven from the machine’s 24 V DC control supply, which is the standard actuator voltage on Sinumerik-controlled machine tools.

Signal Type: digital. Each point is a switched on/off state written by the control’s PLC program, so the card sits between the CNC’s internal logic and the machine’s power wiring.

Controller Platform: Sinumerik 810, 820, 850, 880. The same card serves four control generations, which widens the pool of machines a single spare covers.

Mounting data:

Mounting Type: plug-in printed circuit board. The card slides into a slot in the Sinumerik control rack and takes its bus connection through the backplane, with the field wiring landed on the front connector.

Item Weight: 1.20 kg (2.65 lb).

Quantity and configuration:

Unit Quantity: 1 Pc. The listing is for one bare module.

Interchange guidance:

MPN Variants: 6FX1122-8BD01, 6FX11228BD01, 6FX1122 8BD01. The board number 570 228 9104.01 is a Siemens internal reference, not an order number.

Related executions in the same family carry different point counts and signal directions — 6FX1122-8BC01 and 6FX1122-8BD04 are separate cards with their own order numbers, and the last four characters are what decide the execution.
