SIMATIC ET 200SP HA Digital Input Module DI 16x24VDC (6DL1131-6BH00-0PH1) CAN Electric — Industrial Automation Parts Supplier

Built for high-availability process I/O

The module slots onto the ET 200SP HA carrier rail behind the IM 155-6 PN HA interface, feeding sixteen 24 V DC inputs from switches and 2-wire sensors to redundant S7 systems. An output disable switch held for three seconds de-energizes the module, so it can be pulled in RUN without stopping the station.

Diagnostics down to the channel

Every channel reports wire-break, short-circuit to M and supply faults as diagnostic alarms or hardware interrupts, with per-channel status LEDs, a MAINT LED and a PWR LED on the front. Missing sensor supply is monitored module-wide and can be parameterized.

Redundancy and time stamping built in

With the M1 terminal blocks the module joins IO redundancy, covering a failover in at most 55 ms. Time stamping with 1 ms precision records signal changes for sequence-of-events analysis in PCS 7.

Data per the Siemens product documentation and catalogue entry; confirm the current data sheet before wiring the CAN segment or sizing the supply.

Hot swap without stopping the line

The output disable switch de-energizes the module for removal while the station keeps running, and the ET 200SP HA system supports pulling and inserting multiple I/O modules in operation – downtime stays with the plant, not the maintenance window.

Sequence-of-events ready

Time stamping with 1 ms resolution plus hardware interrupts on rising, falling and changing edges give PCS 7 a reliable fault chronology, which shortens root-cause work on process trips.

One module for single and redundant stations

The same electronics run on H1 and M1 terminal blocks; only the M1 pair (dark 0BM1 / light 0DM1) unlocks IO redundancy, so a single spare type covers both station designs.

The module runs on both terminal block types; only M1 unlocks IO redundancy, so choose light or dark by panel colouring and M1 where channel redundancy is configured.

Engineered in PCS 7 from V9.0 via HW Config, the module mounts on an ET 200SP HA carrier module behind the IM 155-6 PN HA interface (6DL1155-6AU00-0PM0), with a server module closing the station. Terminal blocks are ordered separately – H1 or M1, light or dark. Siemens lists the module as an active product (PM300).

• Email sales@can-electric.com with the order number, quantity, delivery country, and whether the module extends a station or replaces a failed one.
• State the condition you need — new, new-surplus or refurbished is written on the quote, never implied.
• Prices are USD and ships go out from Hong Kong by DHL; availability is confirmed per order rather than taken from a catalogue status.
