In a typical retrofit scenario, replace an older 8-bit module with the STBACI1230K to improve measurement accuracy (12-bit) and add hot-swap capability. The low-pass filter (25 Hz) reduces noise on slowly changing signals like tank levels or conveyor speeds.\u003c\/p\u003e\u003cp\u003eAnother application is expanding a Modicon STB island in a new machine build. The kit's two current inputs interface directly with 4-20 mA transmitters (pressure, temperature, flow) without external signal conditioners. The 1500 V isolation ensures operators are safe even during transient faults.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eSchneider STBACI1230K\u003c\/strong\u003e is designed for seamless integration with the Modicon STB distributed I\/O solution. It mounts on the STBXBA1000 base and requires a power distribution module (STBPDT3100 or STBPDT3105) for the 24 V DC sensor supply. The kit addresses 4 input words and supports both EN 61131-2 and IEC 61131-2 data formats. Compatibility with standard NIMs enables hot swapping fallback, while basic NIMs use a fixed fallback state. For dual-channel configurations, the STBACI1230K complements other STB analog or digital modules within the same island.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the \u003cstrong\u003eSchneider STBACI1230K\u003c\/strong\u003e, verify that your existing STB base and NIM are compatible. The kit includes the module, base, and connectors; you only need to ensure proper power distribution (STBPDT3100\/3105) and DIN rail mounting.
