Technical Characteristics:
Power supply 24 VDC 230 or 120 VAC 50 or 60 Hz
Number of inputs per unit 8 8
Power supply isolation no yes (1500 VAC)
Inputs opto-isolated no no
Supply output regulated 24 VDC (± 5 %) - 100 mA
Signal level of the input, nominal value 24 VDC 24 VDC
Signal level of the input :
0 - OFF signal –3 to +5V –3 to +5V
1 - ON signal +15 to +30V +15 to +30V
Open circuit detection* yes yes
Input current for 24 VDC 6 mA 6 mA
Input delay 8 ms 8 ms
Maximum power consumption 0.2 A 10 VA
Maximum power dissipation 4.5 W 8 W
* A 20 to 30 kOhm resistor must be mounted in parallel of each input captor to get open
circuit detection for that channel. With an inductive captor, the minimal current is 1 mA.
