Unit Description

Figure R1.1 shows the layout of the RBE2-8 Networked Relay Board.

Figure R1.1 RBE2-8 Layout

1) The RBE2-8 can be mounted on a DIN rail or directly on a panel. The four outer screws on the unit, and

the included two brackets, allow you to change how the unit is mounted. Instructions, and dimensional
drawings of the two configurations, can be found in the

Installing the RBE2-8

section of the manual,

starting on page 19.

2) Two RJ45 Ethernet jacks. The two ports are connected through an embedded two port switch. Both ports

feature auto-switch and auto-MDIX functionality. They will automatically adjust to the speed of your
network, and crossover cables are never needed. In non-redundant networks, either port can be used to
connect to your host controller and the other port can be used to extend the network if this would reduce
wiring costs. In redundant networks, both ports are used. There is a Link Activity LED on each connector.
See the

Status LEDs

section starting on page 9 for a description of these LED’s.

3) Status LED’s. The Module Status and Network Status LED’s indicate the state of the unit and the network

connection. The state of the LED’s is determined by the protocol the RBE2-8 is configured for. See the

Status LEDs

section starting on page 9 for a complete description.

4) Output Mode momentary pushbutton and LED. Allows you to disable the outputs from the relay board

regardless of the state of the network data. Press the button to toggle between its Active and Disabled
states. The LED is red when the outputs are disabled by the switch and green when the outputs are
controlled by the network data.

5) Communication Error Mode switch. This slide switch is used to specify what state the output take if the

network connection is lost. When the switch is off, the outputs retain their last state. When the switch is on,
all of the outputs turn off if the network connection is lost. The state of this switch is only read when power
is applied to the relay board or when the relay board is reset with the “Reset Module” button.

6) Reset Module momentary pushbutton. This pushbutton can be used to force the RBE2-8 to re-read the state

of the Communication Error Mode switch and/or disconnect and reconnect to the network. If you
disconnect the RBE2-8 from your host controller and attach it to your PC to troubleshoot or reconfigure the
relay board, press the Reset Module switch to force the RBE2 to drop all connections to the host controller
and create new ones with your PC.

7) Relay hold down bar and thumb screws. This bar and thumb screws are used to keep the relays in place in

applications that are subject to shock and vibration.

8) Eight Output Relays. The relays are field replaceable. A variety of AC and DC relays are compatible with

the RBE2-8. See

Compatible Relays

, starting on page 11, for information on compatible relays. Please

note that relays are not included with the RBE2-8.
