2 channel analog output board
The Automation and Electronics, Inc. SRAO board was designed to provide analog output expansion capabilities for the SRTU simple RTU.
The SRAO is a two channel 4-20 mA analog output daughter board that plugs onto the SRTU board. The outputs require an external 24 VDC source to supply power for both current loops.
- Two each 16-bit 4-20 mA analog outputs (SRTU provides 12-bit data)
- Supply can be isolated or non-isolated
- LED fault indicators for open loop conditions
