PD 620 4 Channel Digital I/O

Specific Features

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.

· 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.
