Description

The LNK-AO Analog Output peripheral device adds four channels of 4 – 20 mA analog output to a Modbus® RS-485 network configured with one of the FCS Multi Channel System Controllers. The LNK-AO is designed to send a 4 – 20 mA signal to up to four devices such as a data / trend / logging system, a BAS or DDC or up to four VFDs.

The four 4-20 mA output signals are current sourced and can be independently scaled using the menu system on the controller. Each output can be assigned to an individual sensor or to a group of sensors through zoning configured within the controller. Communication with the controller is monitored and if interrupted a pre-configured default current will be output in each channel.
