Key Features
SM 322 provides 8 digital outputs with potential separation between channels in groups of 8 and optocoupler separation from the backplane bus.
Rated load voltage is 24 V, with a permissible range from 20.4 V to 28.8 V.
Output current for signal "1" has a rated value of 0.5 A; the permissible range is 10 mA to 0.6 A for 0 to 40 °C and 40 to 60 °C.
The outputs have electronic short-circuit protection, parameterizable diagnostics and diagnostic alarms, plus wire-break, short-circuit, and missing-load-voltage diagnosis.
A 20-pin front connector is required for connection.
The module measures 40 mm wide, 125 mm high, and 120 mm deep; weight is approximately 210 g.
Frequently Asked Questions
