Functional Devices RIBD02BDC : Dry Contact Time Delay Relay, 20 Amp SPDT, Class 2 Dry Contact Input, 208-277 Vac Power Input, NEMA 1 Housing

Functional Devices RIBD02BDC : Dry Contact Time Delay Relay, 20 Amp SPDT, Class 2 Dry Contact Input, 208-277 Vac Power Input, NEMA 1 Housing

Product Features

• Prepackaged for quick and easy installation
• Provides low-voltage (Class2) power needed to activate the relay (self-powered) by closing the dry contact input
• Activated by a wide range of dry contacts such as thermostats, switches, other relays, solid-state switches, etc.
• Power to energize the relay can be brought to the relay on a separate pair of wires along with the control output of the controller, or can be a local power source near the relay
• Relay contacts are isolated from the input power and the dry contact input, so they can be wired to switch any other power-load or low-voltage load (see specifications for contact ratings)

Notes:

• Dry Contact Input Operation:
  Mode A&C: Close White/Red wire to White/Blue wire to start timing. Relay will activate after timing sequence has ended.
• Mode B&C: Open White/Red and White/Blue wires to start timing. Relay will deenergize after timing sequence has ended.
• If more than one dry contact RIB® shares a single dry contact input, White/Blue must be common
• Changing min/sec or mode while unit is running will reset the unit (de-energize the relay and turn off the timer). Once the dry-contact input is opened the unit will function as normal again
• If the unit is powered up with the dry-contact input closed, the unit will begin timing (MODE A and MODE C) or energize the relay (MODE B).
