© Siemens AG 2016 Process Protection Acoustic sensors for material flow monitoring SITRANS CU02 control unit ■ Overview ■ Technical specifications Mode of operation Measuring principle Controller for acoustic sensing (SITRANS AS100) Typical application Connects to SITRANS AS100 to detect burst filter bag Input 0 … 10 V DC, from sensor Output Output signal 4 … 20 mA isolated output, 2 Form C relays - latching or non-latching - 5 amp at 250 V AC non-inductive Sensor excitation 26 V DC Max. load 750 Rated operating conditions Installation conditions • Location SITRANS CU02 is an alarm control unit, for use with SITRANS AS100 acoustic sensor, that provides reliable continuous protection for bulk solids flow. ■ Benefits 6 • • • • • • 4 to 20 mA output Two programmable relays Adjustable independent time delay for each relay Adjustable start-up time delay DIN rail mounting provides easy installation Built-in password protection to parameters ■ Application SITRANS CU02 receives a 0 to 10 V DC input signal from the SITRANS AS100 sensor, providing relay and analog outputs for interface into a process. • Key applications: with SITRANS AS100 for bulk solids flow • Degree of protection • Installation category • Pollution degree Indoor -20 … +50 °C (-4 … +122 °F) 80 % for temperatures up to 50 °C (122 °F) IP20 II 2 Design Weight 550 g (18 oz) Dimensions (W x H x D) 55 x 75 x 110 mm (2.2 x 3 x 4.4 inch) Material enclosure Polycarbonate Mounting DIN Rail (DIN 46277 or DIN EN 50022), or wall mount, up to 500 m (1 500 ft) from sensor Cable 2 twisted pair, 24 AWG (22 mm²), shielded. Mount up to 500 m (1 500 ft) from sensor Display Liquid crystal, three digits, 9 mm (0.35 inch), high and multi-segment graphic symbols for operation status Power supply ■ Function The system can be readily configured for set points indicating such conditions as high flow, low flow or no flow. Alternatively, it can be added to a control loop via a 4 to 20 mA isolated output for trend monitoring proportional to the signal from the sensor. Two relays are fully programmable and independent of each other and can be used to operate an alarm or control device. Alarming may be provided above or below a setpoint or within a band. Readings are also displayed locally by the SITRANS CU02 on its LCD. The SITRANS CU02 may be mounted up to 500 m (1 500 ft) from the sensor. 6/14 Ambient conditions • Ambient temperature for enclosure • Relative humidity Siemens FI 01 · 2016 Supply voltage 100, 115, 200, 230 V AC ± 15 %, 50/60 Hz, factory set Power consumption Max. 10 VA Approvals CSAUS/C, CE, RCM, EAC © Siemens AG 2016 Process Protection Acoustic sensors for material flow monitoring SITRANS CU02 control unit Selection and Ordering data Article No. Selection and Ordering data SITRANS CU02 Control Unit Alarm control unit for use with SITRANS AS100 acoustic sensor to provide reliable continuous protection for bulk solid flow 7 MH7 5 6 2 - Further designs 777 Please add "-Z" to Article No. and specify Order code(s).
