Maximum output frequency at frequency output ....................................................................... 32 kHz
Accuracy of frequency output .................................................................. Max. e rror: 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 supp ly voltage (P ELV) 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 g alv o nically is olated from the supply voltage (PELV), but has the sa me
potential as the analog and digital inputs and outputs.
