PD620

• 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.

APPLICATION
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.
