System Description
Outputs and Communications
FALCO has six communication outputs:
•
The on-board LCD and LEDs on the faceplate.
•
4 - 20 mA Current Loop.
•
RS485 Modbus.
•
Two programmable relays.
Real-time information is displayed on the LCD and transmitted on the 4 - 20 mA and RS485 channels.
You can program two alarms to operate at a chosen concentration of gas. The alarms will display a message on
the LEDs, energise the relays, and transmit a signal on the 4 - 20 mA channel.
The alarms and relays are individually programmable to the settings required by the site policy. You can
choose either alarm to energise either relay.
Both relays can be programmed to switch 60 VDC / 2 A or 50 VAC / 2 A maximum load.
