Product information
Overview
Key Features
- Digital output capacity: 16 isolated digital outputs with relay contacts; parallel switching is not supported for uprating, but is supported for redundant load control.
- Load voltage ratings: Rated load voltage is 120 V DC for L+ and 230 V AC for L1.
- Output current: Signal "1" rated output current is 2 A, with a minimum load current of 10 mA.
- Relay coil supply: The relay coil has a rated supply voltage of 24 V DC.
- Electrical separation: Digital outputs have potential separation between channels and between channels and the backplane bus; separation is in groups of 8, with an optocoupler to the backplane bus.
- Front connection and dimensions: The required front connector is 20-pin. Dimensions are 40 mm wide, 125 mm high, and 120 mm deep.
