BAPI ETA R49 Module

R49 - Relay Interface, 9 Output
Electronic Technician Assistant (ETA)

It is often necessary to perform several tasks simultaneously in an HVAC system – for example, turn on an auxiliary supply fan, turn on an exhaust fan, open purge dampers and close return dampers. Rather than tying up four I/O spots on the controller to perform these tasks, the BAPI R49 conserves critical controller space by turning on or off up to nine relays using only one controller output.
Each output on the R49 module has a polarity switch so that some loads may be turned off while others are turned on as the input changes state.
Each R49 output supplies a nominal 24 VDC at 120 mA allowing it to control most common relays or small contactors. Each output has a red LED to indicate when power is present.
The R49 plugs into a BP4 or BP8 Backplane. A green LED indicates that power is present to the module.

ASSOCIATED ETA PRODUCTS

PS17 or PS17CB - Power Supply Fuse Blocks
Each PS17 or PS17CB provides up to six fused or breakered 33 VDC power supplies to operate any of the BAPI ETA modules except the FOX & RPTR RS-485 communication modules.

TRK18 - Snaptrack
All good projects need a proper foundation and the ETA modules are no exception. The TRK18 - Snaptrack provides a sturdy, secure and easy mounting method for the ETA line.

BP2, BP4 or BP8 - Interface Backplane
The BP2, BP4 and BP8 Backplanes provide a convenient way to mount and power the BAPI ETA interface devices which helps cut down on control panel and control room clutter. Connectors on the face of each Backplane plug into mating connectors on the ETA modules. The BP8 accommodates eight modules while the BP4 accommodates four modules and the BP2 accommodates two modules.
