RIBTW2421B-BCIP BACnet IP Network Relay Device

Product Usage Instructions

Dry Contact Binary Input Usage

• The dry contact binary input is a general-purpose input that is not tied to the relay internally.
• It can be used with any dry contact switching device, such as a current sensor, to report back to the network.

Changing Device ID

• The device ID can be changed using DIP SWITCHES or a BACnet configuration tool. The device ID will default to 277XXX where XXX is the decimal value of the last octet of the device’s MAC address.

Power Input Recommendations

When connecting 24 Vac to both the RIB(s and a half-wave device, it is important to avoid damage to the device by following one of the two options:

1. Option 1: Use separate transformers for each device.
2. Option 2: Add a diode between devices. The band on the diode should face towards the RIB(s).

FAQ

• Q: What is the purpose of the dry contact binary input?
• A: The dry contact binary input is a general-purpose input that can be used with external switching devices to provide feedback to the network.
• Q: How can I change the device ID?
• A: The device ID can be changed either through DIP SWITCHES on the device or using a BACnet configuration tool.
• Q: What precautions should I take when connecting power input to the device?
• A: It is recommended to follow the specified power input ratings and avoid connecting 24 Vac to both the RIB(s and a half-wave device simultaneously to prevent damage.
