- Provides four relay outputs with changeover contacts for AC or DC loads
- Keeps every relay channel isolated from the other channels and the X20 bus
- Supports 115 VAC field switching with an external actuator power supply
X20DO4529 is a B&R relay output module designed for X20 System I/O stations.
Each relay channel can switch its own documented field circuit while remaining isolated from the other channels, the X20 bus, and the I/O power supply.
Before installation or replacement, verify the complete material number, load voltage and category, contact current and inrush, minimum switching level, external suppression, relay life, terminal and bus modules, and environmental limits.
Availability, condition, price, and shipping time for X20DO4529 are confirmed during quotation.

- Electrical service life is specified as at least 100,000 operations
- Mechanical service life is specified as at least 50 million operations at 3 hertz
- Actual service life depends on load type, current, inrush, and switching frequency
- Each relay channel is isolated from the other channels
- Channels are isolated from the X20 bus and I/O power supply
- The installed field circuit must remain within the documented isolation and voltage limits
- No protective circuit is integrated across the relay contacts
- AC loads require an external RC combination or voltage-dependent resistor as applicable
- DC inductive loads require an inverse diode, RC combination, or voltage-dependent resistor as applicable
- Switching individually isolated 115 VAC field loads in X20 control stations
- Controlling documented 30 VDC loads through changeover relay contacts
- Distributed machine-control circuits requiring galvanic separation between output channels
