Product details

SIPLUS 32×24 VDC DI — tight panel fit

The 6AG1321-1BL00-2AA0 is a 32-channel digital input module rated for -40 to 70 °C ambient. It takes 24 VDC inputs, signal "1" at 13 V, typ. 7 mA per channel. Backplane supply: 15 mA at 5 VDC, total dissipation 6.5 W. All 32 inputs are available up to 40 °C. At 40–60 °C, 16 inputs are usable; above 60 °C, only 12 inputs remain active. Each input group of 16 is isolated from the other, and the isolation is tested at 500 V DC. No diagnostic alarms, no parameterization — it's a straight read-only input block, minimal firmware overhead. The front connector is a 40-pin type, so plan the wiring harness accordingly.

Panel mounting & wiring — one pass, no surprises

Mechanical: 125×40×120 mm (H×W×D), 260 g. No screws, no tools for the bus link. Wiring: 40-pin front connector (not included). Two-wire sensor compatible. Cable lengths: unshielded up to 600 m, shielded up to 1 000 m. Input filtering fixed — on-delay 1.2 ms min, 4.8 ms max, same off-delay. Use 24 VDC supply (20.4 V to 28.8 V). Isolation across the backplane is non-galvanic between channel groups; the whole module is 500 VDC tested to the frame. No channel-to-channel isolation, so shared ground paths are expected.

Frequently asked questions

What is the closest functional second-source — 6AG1511-1AK01-2AB0?

6AG1511-1AK01-2AB0 is a SIPLUS CPU, not a digital input module. It cannot serve as a replacement or second-source for the 6AG1321-1BL00-2AA0; they serve different functions in the control system.

What is the maximum and minimum ambient temperature rating?

The module is rated for -40 °C minimum and 70 °C maximum ambient temperature. Note that input channel count derates above 40 °C.

Will 6AG1321-1BL00-2AA0 drop into a panel wired for 6AG1511-1AK01-2AB0?

No. The 6AG1511-1AK01-2AB0 is a CPU with its own backplane and power supply connections. The 6AG1321-1BL00-2AA0 is an I/O module that mounts on a separate bus and requires a CPU to operate. Direct wiring compatibility is not possible.

What compliance documentation is available for this module?

The module carries UL (File E239877), CE, EN 50155:2007 (T1 Cat1 Class A/B), KC, EAC, and RCM approvals. Standard compliance documents are included with shipment.
