Output

• Transistor (digital output DO1):

– potential free

– NPN or PNP (wiring dependant)

– function: pulse output, adjustable pulse value

– 0…2200 Hz

– 5…36 V DC, 100 mA max., voltage drop at 100 mA: 2.7 V DC

– duty cycle (pulse duration/period):

– > 0.45 if 0.6 < frequency < 300 Hz

– > 0.4 if 300 < frequency < 1500 Hz

– < 0.4 if 1500 < frequency < 2200 Hz

– galvanic insulation, protected against overvoltage, polarity reversals and short-circuit

• Relays (digital outputs DO2 and DO3):

– 2 relays, normally open, hysteresis, adjustable thresholds

– non UL recognized device: 230 V AC/3 A or 40 V DC/3 A (resistive load)

– UL recognized device: 30 V AC/42 V

peak/3 A or 60 V DC/1 A

– max. cutting power of 750 VA (resistive load)

– life span of min. 100 000 cycles

• Current (analogue output AO1):

– 4…20 mA (3-wire)

– sourcing or sinking (wiring dependant)

– 22 mA to indicate a fault (can be activated)

– max. loop impedance: 1300 Ω at 36 V DC, 1000 Ω at 30 V DC, 750 Ω at 24 V DC, 300 Ω at

15 V DC, 200 Ω at 12 V DC, 900 Ω with a 115/230 V AC voltage supply

Voltage supply cable

• Wall-mounted variant:

– external diameter (cable): 4…8 mm (for the cable glands)
