Product Overview
The Schneider BMXSDI1602 is a safety discrete input module designed for the Modicon X80 range. This industrial automation module features 16 not-isolated inputs operating at 24 V DC positive with a current sink (logic positive) configuration. It is engineered for critical safety applications where reliable signal acquisition and diagnostics are essential. Part of the trusted Schneider BMXSDI1602 series, this module replaces older safety input modules with enhanced performance and reduced maintenance needs.
Technical Specifications
The Schneider BMXSDI1602 delivers precise input parameters to meet demanding automation requirements. Key specifications include:
- Discrete input number: 16
- Discrete input voltage: 24 V DC positive
- Discrete input current: 3.2 mA
- Input type: Current sink (logic positive)
- Input impedance: 7500 Ohm
- Power dissipation: 3.57 W
- DC typical/maximum response time: 6 ms
- Paralleling of inputs: Yes
- Typical current consumption: 256 mA at 3.3 V DC, 100 mA at 24 V
- MTBF reliability: 265,000 hours
Additional environmental protections include reverse polarity protection and external overload protection (0.5 A fast blow). The module features voltage detection thresholds: <14 V DC indicates sensor fault, >18 V DC indicates sensor OK. IP20 degree of protection and conformal coating ensure durability in harsh industrial environments.
Applications
The Schneider BMXSDI1602 is ideal for upgrading safety systems in manufacturing, process control, and material handling. Typical applications include:
- Safety interlock monitoring for robotic cells
- Emergency stop circuit input acquisition in conveyor systems
- Guard door status detection in automated assembly lines
By replacing older non-safety input modules with the BMXSDI1602, facilities can improve fault diagnostics and reduce unplanned downtime, directly supporting modern industry 4.0 initiatives.
Maintenance & Reliability
With an MTBF of 265,000 hours, the Schneider BMXSDI1602 offers exceptional long-term reliability. Routine maintenance includes periodic inspection of the status LEDs: green for module operating (RUN), green per channel for channel diagnostic, red for module error (ERR), and red for module I/O. The conformal coating and environmental resistance (class 3C4, 3S4, etc.) make the module suitable for applications with gas, dust, sand, salt, and mold exposure. Operate within the ambient temperature range of -25°C to +60°C and altitude up to 2000 m (with derating to 5000 m) for optimal performance. The reverse polarity and overload protection reduce component stress, lowering lifecycle costs.
