Bachmann|SDO204 00014545-00|Safety Digital Output Module
Bachmann SDO204 00014545-00 Overview
The Bachmann SDO204 00014545-00 is a safety digital output module designed to provide high-performance, SIL3-certified digital outputs for integration into the M200 controller system.
Features
- 8 digital outputs with redundant pairing capability
- Configurable emergency delay and safe output monitoring
- Galvanic isolation between groups and from the system
Technical Specifications
Digital Outputs

- Output voltage range: 18 V DC to 34 V DC
- Output current per channel: 2 A nominal
- Total current per group (max.): 8 A (derating starts at 40 °C ambient)
- Delay times:
- 0 to 1: Max. 35 µs at full load
- 1 to 0: Max. 155 µs at full load
- Switching frequency (max., resistive load): 500 Hz
- Status indication: Green LED per channel
- Output groups: 2 with electronic fuse
Monitoring & Safety
- Error detection: Short-circuit, overload, undervoltage/overvoltage
- Emergency shut-off: Configurable per output from 0 s to 1800 s (resolution 100 ms)
Power Supply
- Internal supply: 5 V / 250 mA via backplane
- External supply voltage: 24 V DC (range 18 V to 34 V)
