Solution Integration

The RM16DOHW seamlessly integrates with major automation platforms including Siemens S7, Allen-Bradley ControlLogix, Schneider Electric Modicon, and Mitsubishi FX series PLCs. Its universal 24V DC input makes it compatible with standard industrial control voltages, while the relay outputs handle both AC and DC loads up to 6A per channel.

Frequently Asked Questions

Q: Can this module handle inductive loads?
A: Yes, the relay contacts are rated for inductive loads. We recommend using appropriate suppression circuits (RC snubbers or freewheeling diodes) for optimal relay life when switching motors or solenoids.

Q: What is the expected relay lifetime?
A: Mechanical life exceeds 10 million operations. Electrical life depends on load characteristics but typically ranges from 100,000 to 1 million cycles at rated load.

Q: Is hot-swapping supported?
A: The module can be replaced during operation if proper safety procedures are followed, though we recommend de-energizing the system during maintenance.

Q: What wire gauge is recommended?
A: The terminals accept 0.5-2.5mm² (AWG 20-14) solid or stranded wire with ferrules recommended for stranded conductors.
