Maximum current output: 3 W
Fuse to be fitted in series with the power supply of the μC2: 315 mAT
12-pin connector
Max current 2 A for each relay output, extendable to 3 A for one output
Relays
Max current at 250 Vac:
EN60730: Resistive: 3 A, Inductive: 2 A cosφ= 0.4 60000 cycles
UL: Resistive 3 A, 1 FLA , 6 LRA cos φ= 0.4 30000 cycles
For further information, refer to the characteristic shown in Fig. 5
Minimum interval between switching cycles (each relay): 12 s (the manufacturer of

to this specification)
Type of micro-switching of the relay: 1 C
Insulation between relays in group A: functional
Insulation between relays in group A and the very low voltage parts: reinforced
Insulation between relays in group A and the signal relay: primary
Insulation between the signal relay and the very low voltage parts: reinforced
Insulation between relays and the front panel: reinforced
Digital inputs ID1 to ID5, IDB4
Electrical standard: voltage-free contact
Closing current to ground: 5 mA
Maximum closing resistance: 50 W
Analogue inputs
B1, B2, B3, B4: CAREL NTC temperature probes (10 kW at 25 °C)
The response time depends on the component used, typical value 90 s
