Description
Solenoid / Alarm driver, Type ACT20X-SDI-HDO-L-S, Type ACT20X-SDI-HDO-L-P,
Type ACT20X-SDI-HDO-H-S, Type ACT20X-SDI-HDO-H-P and Type ACT20X-2SDI-2HDO-S,
Type ACT20X-2SDI-2HDO-P, for rail mounting, are 24 V powered isolating barriers, converting
digital signals from PLC's and other equipment into signals for driving valves, solenoids and light
emitting diodes located in a hazardous area.
Ambient temperature range -20 °C to +60 °C.
Marking
The equipment marking may additionally include the code II 3 G Ex nA nC IIC T4 Gc.
Electrical data
Supply (terminals 51, 52): U = 19,2 ... 31,2 Vdc.
Digital input (terminals 41, 42 and 43, 44): U ≤ 60 Vdc
Status Relay (terminals 53, 54):
U ≤ 32 Vdc or 32 Vac, I ≤ 1 Adc or I ≤ 0,5 Aac respectively.
If the Solenoid / Alarm driver is installed outside the hazardous area, the following data for the
relay contacts apply: U ≤ 110 Vdc or 125 Vac, I ≤ 0,3 Adc or I ≤ 0,5 Aac respectively.
For all circuits above: U
m
= 253 Vac (max. frequency 400 Hz).
