Technical specifi cations
Power supply 230 Vac, range –15 to +10%; 50/60 Hz; maximum power input: 1.5 VA
Screw termninals max voltage: 230 V
cable cross-section: 14-22 AWG
the current input from the mains (sum of the current inputs of the loads, the main board, the expansion and
the external module) must not exceed 6 A.
0 to 10 Vdc outputs No4, No5 minimum impedance of the 0 to 10 Vdc actuator input stage (damper, valve,…): 10 KOhm
Relay outputs No4, No5, No6, No7 maximum current at 250 Vac: - EN60730: resistive 2 A, inductive: 2 A cos(j)=0.4 60000 cycles
type of relay action-microswitching: 1C
For the voltage outputs No4 and No5 respect the maximum limits described in the fi eld “screw terminals”.
minimum interval between switching cycles (each relay): 12 s (the manufacturer of the unit that the device is
integrated into must guarantee the correct confi guration to respond to this specifi cation)
type of relay action-microswitching: 1C
Insulation insulation between low (relay outputs) and very low voltage parts: reinforced
insulation between outputs with voltage signal No4, No5 and outputs No6, No7: reinforced
insulation between outputs No6 and No7: reinforced.
If using serial boards, output No7 can be limited to very low voltage only. See the user manual.
