Bachmann DI016-C Digital Input/Output Module
1. Product Description
A compact, industrial-grade digital input/output (DIO) module designed for 中小型 (small-to-medium) distributed automation systems. The Bachmann DI016-C integrates 16 configurable channels (8 input/8 output default, fully reconfigurable via software) and operates as a slave device, enabling seamless integration with master controllers (e.g., Bachmann MPC240) or bus masters (e.g., FS212/N) via standard industrial protocols. It features robust electrical protection, low power consumption, and compatibility with Bachmann backplanes—ideal for harsh industrial environments requiring localized signal acquisition and control (e.g., machine-level I/O, small production cells).
2. Detailed Specifications

- Inrush Current: <1.5 A (per output channel, initial activation)
2.4 Power Supply
- Input Voltage: 24 V DC ±20% (powered via external supply or Bachmann backplanes)
- Power Consumption: Typical 3 W, Maximum 5 W (excluding load current)
- Power Protection: Overvoltage, undervoltage, reverse polarity, and surge protection (EN 61000-4-5)
2.5 Operating Environment
- Operating Temperature: -40°C ~ +70°C
- Storage Temperature: -40°C ~ +85°C

- Vibration Resistance: 10-500 Hz, 2 g acceleration (IEC 60068-2-6)
- Shock Resistance: 30 g acceleration, 11 ms duration (IEC 60068-2-27)
- EMC Compliance: EN 61000-6-2 (industrial immunity), EN 61000-6-4 (industrial emissions)
2.6 Physical & Software
- Dimensions: 90×75×28 mm (Length×Width×Height)
- Mounting: DIN rail (EN 50022 standard); compatible with Bachmann BS203/BS204 backplanes
- Software Support: Bachmann Studio (v4.0+; I/O configuration, protocol setting, fault diagnostics)
- LED Indicators: 16 channel LEDs (green: input on; red: output on); 2 communication LEDs (green: active; red: fault); 1 power LED (green)
3. Advantages & Features
- Compact 16-Channel Design: Small form factor saves cabinet space—ideal for machine-level or space-constrained systems.
- Flexible I/O Configuration: 8/8 default ratio adjustable via software, adapting to variable input/output needs (e.g., sensor-heavy or actuator-heavy setups).
- Dual-Protocol Communication: Supports Modbus/Profinet IO, integrating with both Bachmann and third-party master controllers.
- Cost-Effective Slave Solution: Balances functionality and price, perfect for small distributed cells or budget-conscious projects.
- Rugged Industrial Build: Wide temperature range and surge protection ensure reliability in harsh machine environments.
4. Application Fields
- Machine-Level Control: Standalone machinery (e.g., 3D printers, small CNC routers) – sensor input (limit switches) and actuator control (solenoids).
- Small Production Cells: Electronics assembly workstations (e.g., PCB testing machines) – part presence detection and tool activation.
- Building Automation Zones: Office floor HVAC sub-systems – temperature sensor input and damper actuator control.
- Agricultural Equipment: Greenhouse ventilation systems – humidity sensor input and fan motor control.
- Retail Automation: Automated checkout kiosks – barcode scanner input and receipt printer output.
5. Precautions
- Slave Setup: Assign unique IP/node ID to avoid communication conflicts; test master-slave connectivity before live operation.
- Wiring: Use 0.5-1.5 mm² shielded cables for I/O/communication; ground shields at the master end to reduce EMI; separate power and signal lines.
- Load Limits: Do not exceed 0.3 A per output channel; use external relays for high-current loads (>0.3 A, e.g., small motors).
- Backplane Compatibility: Only use with Bachmann BS203/BS204 backplanes; ensure backplane power is off during module insertion/removal.
- Maintenance: Inspect RS485/Ethernet connectors quarterly (clean with dry brush); back up configuration via Bachmann Studio; do not disassemble (voids warranty).
