FC 300 Instruction Manual
General Specifications
Control card, RS 485 serial communication:
Terminal number ................................................................................... 68 (TX+, RX+), 69 (TX-, RX-)
Terminal number 61 ....................................................................... Common for terminals , 68 and 69
The RS 485 serial communication is functionally separated and galvanically iso-
lated from the supplier voltage (PELV).
Control card, USB serial communication:
USB standard ............................................................................................................. 2 (low speed)
USB plug .................................................................................................... USB type B "device" plug
Connection to PC is done via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Relay outputs
Programmable relay outputs ............................................................................. FC 301: 1 / FC 302: 2
Terminal number, power card ...................................... 1-3 (break), 1-2 (make), 4-6 (break), 4-5 (make)
Max. terminal load (AC) on 1-3 (break), 1-2 (make), 4-6 (break) power card ...................... 240 V AC, 2 A
Max. terminal load (AC) on 4-5 (make) power card ......................................................... 400 V AC, 2 A
Min. terminal load on 1-3 (break), 1-2 (make), 4-6 (break), 4-5 (make) power
card ................................................................................................ 24 V DC 10 mA, 24 V AC 100 mA
Environment according to EN 60664-1 ................................. overvoltage category 111/pollution degree 2
The relay contacts are galvanically isolated from the rest of the circuit by reinforced isolation (SELV).
Cable lengths and cross -sections:
Max. motor cable length, shielded/armored ..................... FC 301: 164 ft (50 m) / FC 302: 492 ft (150 m)
