Key Features
Supports 8 channels in groups of 8, with 8 channels for current measurement, 8 for voltage measurement, 4 for resistance/resistance thermometer measurement and 8 for thermocouple measurement.
Supports 1 V to 5 V, -1 V to +1 V, -10 V to +10 V, -2.5 V to +2.5 V, -250 mV to +250 mV, -5 V to +5 V, -50 mV to +50 mV, -500 mV to +500 mV, -80 mV to +80 mV, 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA.
Provides 16 bit resolution and 0.3% accuracy; the basic error limit at 25 °C is 0.1% for voltage, current and resistance relative to the input range.
Uses a rated 24 V DC supply with a permissible range of 19.2 V to 28.8 V, reverse polarity protection and encoder supply short-circuit protection.
Has diagnostics, diagnostic and limit value alarms, hardware interrupts, wire-break detection for 1 V to 5 V, 4 mA to 20 mA, TC, R and RTD, and overflow/underflow detection.
Delivery includes the infeed element, shield bracket and shield terminal. The front connector with screw terminals or push-in is ordered separately.
