Digital inputs
[DI1..DI5]
5 Type: voltage free with closing current for ground
Closing current for ground: 0.5 mA
4 EWCM4120:
relay 2A resistive 250V
Digital outputs 110Vac/230Vac
[DO1..DO4 e DO6]
5 EWCM4150 and EWCM4180:
relay 2A resistive 250V
Triac output*
[TC]
1 EWCM4120:
Triac 2A max 250V output
Low voltage digital output
[DO5]
1 Open collector, max current 35mA**
1 AO1 for model EWCM4120:
Max current 35mA** (min load of 600 Ω with 12Vc)
Analogue outputs
(PWM/Open collector)
[AO1 and AO2]
2 AO1+AO2 for models EWCM4150 and EWCM4180:
Max current 35mA** (min load of 600 Ω with 12Vc)
Low voltage analogue outputs
(0..10Vcc / 4..20mA)
[AO3]
1 EWCM4150 and EWCM4180:
For output 0…10Vc, max 20mA a 10Vc (min load resistance 500Ω).
For output 4…20mA max (max load resistance) 350 Ω
*Remote control switches downstream from the Triac are NOT permitted, since they have a “holding current”
(minimum current necessary to keep it turned on) above 50mA: cannot pilot loads, such as remote control switches,
which have a lower current.
** Outputs AO1, AO2 and DO5 will not activate at the same time with currents greater than 20mA
