FC 300 Design Guide
Analog output:
Number of programmable analog outputs ......................................................................................... 1
Terminal number ......................................................................................................................... 42
Current range at analog output ....................................................................................... 0/4 - 20 mA
Max. load to common at analog output ..................................................................................... 500 Ω
Accuracy on analog output ..................................................................... Max. error: 0.5% of full scale
Resolution on analog output .................................................................................................... 12 bit
The analog output is galvonically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control card, RS-485 serial communication:
Terminal number .............................................................................. 68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61 ......................................................................... Common for terminals 68 and 69
The RS-485 serial communication circuit is functionally separated from other central circuits
and galvanically isolated from the supplier voltage (PELV).
Digital output:
Programmable digital/pulse outputs ................................................................................................ 2
Terminal number ................................................................................................................ 27, 29
Voltage level at digital/frequency output ................................................................................. 0 - 24 V
Max. output current (sink or source) ........................................................................................ 40 mA
Max. load at frequency output ................................................................................................... 1 kΩ
Max. capacitive load at frequency output .................................................................................... 10 nF
Minimum output frequency at frequency output ...........................................................................
Maximum output frequency at frequency output ....................................................................... 32 kHz
Accuracy of frequency output .................................................................. Max. error: 0.1% of full scale
Resolution of output frequency ................................................................................................. 12 bit
1) Terminal 27 and 29 can also be programmed as input.
The digital output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control card, 24 V DC output:
Terminal number ................................................................................................................... 12, 13
Max. load ...................................................................................... FC 301: 130 mA / FC 302: 200 mA
The 24 V DC supply is galvonically isolated from the supply voltage (PELV), but has the same
potential as the analog and digital inputs and outputs.
Relay outputs:
Programmable relay outputs ............................................................................. FC 301: 1 / FC 302: 2
Relay 01 Terminal number .............................................................................. 1-3 (break), 1-2 (make)
Max. terminal load (AC-1)
Max. terminal load (AC-15)
Max. terminal load (DC-1)
Max. terminal load (DC-13)
Relay 02 (FC 302 only) Terminal number .......................................................... 4-6 (break), 4-5 (make)
Max. terminal load (AC-1)
Max. terminal load (AC-15)
Max. terminal load (DC-1)
Max. terminal load (DC-13)
Max. terminal load (AC-1)
Max. terminal load (AC-15)
Max. terminal load (DC-1)
