Key Features
16 isolated digital outputs with relays.
Rated load voltage is 60 V DC or 230 V AC.
Signal "1" rated output current is 5 A; minimum load current is 11 mA.
Short-circuit protection: No. Controlling a digital input: Yes; possible.
Maximum switching frequency is 10 Hz with resistive load, 1 Hz with inductive load to IEC 60947-5-1 DC13/AC15, 1 Hz on lamp load, and 20 Hz mechanically.
Outputs have potential separation between channels in groups of 2 and between channels and the backplane bus. Isolation is tested with 1 500 V AC.
