Analog I/O module DC-AI

voltagecurrent4 analog inputs

The I/O module for analogue input is designed to record voltages of -10 to +10 V and current signals of 0/4 to 20 mA. Laboratory apparatus, such as thermostats, mixers or measuring sensors, can be connected to the four potential-free and EMC robust inputs. Sensors with two and four-wire connections may be connected directly to a module, in other words without any external current supply. Thus, the connection only requires a few seconds, as there is no need for switching to a current supply source. • 4 analogue inputs for voltage and current • Integrated sensor supply • Two- and four-wire connection • Highly accurate thanks to the precise 24-bit analogue/digital converter • Signal : 0/4…20 mA and -10…+10 V • Connection type : Plug-in connectors with push-in spring connection or optionally pluggable screw terminals. • Resolution (effective) : 18 Bit • Measurement range : Voltage: –0.1…+0.1 V; -1…+1 V; -10…+10 V; Current: 0/4…20 mA • Absolute measurement uncertainty from final value (within the maintenance interval) : -10…+10 V: 0.05 %; -1…+1 V: 0.05 %; -0.1 V…+0.1 V: 0.05 %; 0/4…20 mA: 0.15 % • Operating voltage : 24 V (18…30 V), Versorgung über Bus • Power consumption : 60 mA • Dimensions (HxWxD) : 99.5 x 22.5 x 114.5 mm • Working temperature : 0…+60 °C • Storage temperature : 0…+65 °C • Humidity : 90 %, not condensing • Input resistance : approx. 1 MOhm • For the recording of : Analog signals such as pressure, level, stirrer speed, torque, temperature measurement of a thermostat, pH value via IL-PHAMP1 (external), etc.
