7. 代表的な用途

包装機械, textile equipment, printing presses, legacy production line retrofits; used for signal acquisition from proximity switches and pushbuttons, and driving small loads such as solenoid valves and indicator lamps.

⚠️ Selection & Maintenance Precautions

1. Output is Sourcing type (PNP). Connect load negative terminal to 0 V; cannot be directly wired for sinking drive.
2. Do not exceed 0.5 A continuous current per channel; total module output current must not exceed 8 あ.
3. Freewheeling diodes must be wired in parallel for inductive loads (電磁弁).
4. System2005 backplane modules cannot be plugged directly into X20 bases; backplane bus protocols are incompatible.
5. When purchasing discontinued spare parts, distinguish refurbished / used / brand-new surplus stock and confirm warranty terms.

If required, I can provide:

1) Complete terminal pin assignment table

2) Standard DI/DO wiring schematic

3) Configuration key points for Automation Studio hardware setup

11. Mandatory Safety Instructions
12. Module insertion / removal must be performed with power disconnected! Hot-plugging System2005 backplane modules is strictly prohibited; it may permanently damage backplane bus interfaces.
13. Implement ESD protection before handling; wear anti-static wrist strap. Circuit boards are sensitive to electrostatic discharge.
14. Fuses must be installed for external 24 VDC電源; reverse polarity of power supply is forbidden.
15. Freewheeling diodes must be fitted in parallel to inductive loads (電磁弁, 接触器) driven by output channels.
16. Module protection rating IP20, installation inside control cabinet only. Do not expose directly to dust or moisture.
17. Galvanic isolation exists between DI bank and DO bank; no channel-to-channel isolation. Separate low-level I/O cables from power cables during wiring.

Main Module

モデル: 3DM486.6

チャンネル: 16×DI (24 VDC Sink/Source) + 16×DO (24 VDC Sourcing transistor output, 0.5 チャンネルごとに)

Terminals to be ordered separately (Not supplied with module)

7TB718.9: 18-pin screw terminal block, max conductor cross-section 1.5 mm²

7TB718.91: 18-pin Cage Clamp spring terminal block, max conductor cross-section 1.5 mm²

Quantity required: 2 端子台 (X1 for DO, X2 for DI)

3. Mechanical Installation Steps for System2005 Backplane
4. Confirm complete power-off of the entire PCC rack; isolate the power supply module from mains.
5. Align the bottom guide slots of the module with the DIN rail backplane guides and slide horizontally into the slot.
6. Press the side latches inward until an audible click confirms the module is locked to the backplane.
7. Verify the rear gold-plated bus connector is fully seated against the backplane connector without tilting or gaps.

⚠️ Do not pry the module with screwdrivers. 削除するには, release side latches and pull the module out parallel to the backplane.

5. Vertically insert the 7TB718 terminal plugs into the lower X1 and X2 sockets of the module until fully engaged.

Mounting Clearance Requirements

Maintain minimum 25 mm ventilation space above and below each module;

使用周囲温度 0 ℃～ +60 ℃. Implement cabinet temperature reduction if operating continuously above 55 ℃.

4. Complete Terminal Pin Assignment

X1 = Output Terminal (DO1~DO16)

X2 = Input Terminal (DI1~DI16)

X1 (DO Output, 18 ピン)

✅ Output Type: 調達 / PNP Output

When DO is activated, +24 V is present on DO pin. Connect one terminal of load to DO, the other terminal to 0 V.

X2 (DI Input, 18 ピン)

Two DI Wiring Configurations

1. PNP Sensor (Sourcing Type)

Sensor positive → DI channel; Sensor negative → 0 V; Connect module X2.18 to field 0 V

2. NPN Sensor (Sinking Type)

Sensor positive connected to 24 V; Sensor output → DI channel; Connect module X2.17 to field +24 V

Input hardware filter: に固定 1 MS, non-adjustable via software.

DO LED ON: Output enabled in program and hardware output switched ON

Power status: Standby LEDs illuminated when backplane supply is normal; no LED response upon backplane communication failure.

8. Automation Studio Hardware Configuration Guidelines
9. Minimum supported AS version: V2.6 and above
10. Hardware library selection: `3DM486.6` System 2005 DM module
11. Address mapping: Follow rack slot sequence; slot numbering starts from CPU and extends backward
12. Diagnostics support: Software readable faults for output short-circuit and overload

重要: Cannot be installed directly onto X20 backplane; bus protocols are incompatible!
