Thermal relay URB40

Expansion for universal relay (UR) with additional relay outputs, communication via Modbus RTU.

URB40 relay extension box, for universal UR relay box.

The universal relay box URB40 is an expansion box for UR devices, which can be used to control up to four additional relay outputs via Modbus RTU protocol. URB40 monitors communication between devices and can reset each relay output to a predefined state upon exceeding a time limit.

The device has no operational elements and is controlled and configured solely via RS-485 interface.

Application:

With URB40, four additional alarms and relays are available, and the device can also be easily managed in other control systems via integrated RS485 interface.

• - 4 additional alarms
• - No additional control system required
• - Easy expansion of existing UR series control systems
• - Space-saving during installation

Control Voltage:

• DC/AC 24-270 V 0/50/60 Hz

Output Relay:

• 4 x 1 changer max. AC 300 V; DC 300 V

Interfaces:

• RS485 (Modbus RTU)
