Product information
Overview
Key Features
- Analog input capacity: 8 analog inputs, with 8 channels for current measurement and 8 channels for voltage measurement; channels are separated in groups of 1.
- Supported signals: Supported input ranges include 1 V to 5 V, -10 V to +10 V, -2.5 V to +2.5 V, -5 V to +5 V, 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA.
- Resolution and accuracy: Resolution with overrange is up to 24 bit including sign. Operational error limits are 0.1% for voltage and current relative to the input range.
- Signal connections: Supports voltage measurement, current measurement as a 2-wire transducer with external transmitter supply, and current measurement as a 4-wire transducer.
- Diagnostics and status: Diagnostics, diagnostic alarms, limit value alarms, supply-voltage monitoring, wire-break detection for 1 … 5 V and 4 … 20 mA, and overflow/underflow detection are supported.
- Supply and delivery configuration: Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V DC and reverse polarity protection. Delivery includes the infeed element, shield bracket and shield terminal; the front connector with screw terminals or push-in is ordered separately.
