Digital I/O module PD620

currentvoltageconfigurable

• Individually Configurable Digital I/O’s for nominal 24 volts signals and 1 amp (2 Amp) loads, Built in input and output functions, • Individually Configurable Digital I/Os for nominal 24 volts signals and 1 amp (2 Amp) loads. • Built in input and output functions. • Autonomous counting to 200 Hz • Load current measurement • Input Voltage measurement and scaling • Overload/Underload protection and Alarming. • Advanced internal self testing. • Wide power supply range. • Wide temperature range. The PD 620 has four independent digital channels capable of being configured for input or output. Each channel is also capable of measuring a scaled voltage input, and can therefore be used as an analogue input device. It can be used with the BM 014 for direct I/O terminals or the BM 008 base module, where four output channels can be used with the four built in relays.
