• Maximum terminal load: AC-1 resistive load: 240V AC 2 A AC-15• Inductive load @cos ф 0.4: 240 V AC 0.2 A DC-1• Resistive load: 24 V DC 1 A DC-13• Inductive load: @cos ф 0.4: 24 V DC 0.1 A• Minimum terminal load: DC 5 V: 10 mA• Maximum switch rate at rated load/min. load: 6min-1/20 s-1• Ordering number 130B1110 uncoated–130B1210coated (Class G3/ISA S71.04-1985)Analog I/O option MCB 109This analog input/output option is easily fitted in thefrequency converter for upgrading to advancedperformance and control using the additional inputs/outputs. This option also upgrades the frequency converterwith a battery backup supply for the clock built into thefrequency converter. This provides stable use of allfrequency converter clock functions as timed actions.• 3 analog inputs, each configurable as bothvoltage and temperature input.• Connection of 0–10 V analog signals as well asPT1000 and NI1000 temperature inputs.• 3 analog outputs each configurable as 0–10 Voutputs.• Included back-up supply for the standard clockfunction in the frequency converter The back-upbattery typically lasts for 10 years, depending onenvironment. Ordering number 130B1143uncoated – 130B1243 coated (Class G3/ISAS71.04-1985).PTC thermistor card MCB 112With the MCB 112 PTC thermistor card, all Danfossfrequency converters with STO can be used to supervisemotors in potentially explosive atmospheres. MCB 112offers superior performance compared to the bult-in ETRfunction and thermistor terminal.• Protects the motor from overheating.• ATEX-approved for use with EX d and EX emotors.• Uses the safe torque off function of Danfossfrequency converters to stop the motor in case ofover temperature.• Certified for use to protect motors in zones 1, 2,21, and 22.• Certified up to SIL2.Sensor input card MCB 114The option protects the motor from being overheated bymonitoring the bearings and windings temperature in themotor. The limits, as well as the action, are adjustable andthe individual sensor temperature is visible as a read out inthe display or by field bus.• Protects the motor from overheating.• 3 self-detecting sensor inputs for 2 or 3 wirePT100/PT1000 sensors.• One additional analog input 4–20 mA.Extended cascade controller MCO 101Easily fitted and upgrades the built-in cascade controller tooperate more pumps and more advanced pump control inmaster/slave mode.• Up to 6 pumps in standard cascade set-up• Up to 6 pumps in master/slave set-up• Technical specification: See MCB 105 relay optionExtended relay card MCB 113The extended relay card MCB 113 adds inputs/outputs toVLT® AQUA Drive for increased flexibility.• 7 digital inputs: 0–24 V• 2 analog outputs: 0/4–20 mA• 4 SPDT relays• Rating of load relays: 240 V AC/2 A (Ohm)• Meets NAMUR recommendations• Galvanic isolation capability Ordering number130B1164 uncoated – 130B1264 coated (ClassG3/ISA S71.04-1985)MCO 102 advanced cascade controllerExtends the capabilities of the standard cascade controllerbuilt into frequency converters.• Provides 8 additional relays for staging ofadditional motors.• Provides accurate flow, pressure, and level controlfor optimising the efficiency of systems that usemultiple pumps or blowers.• Master/slave mode runs all blowers/pumps at thesame speed, potentially reducing the energyconsumption to less than half that of valvethrottling or traditional, across-the-line on/offcycling.• Lead-pump alternation assures that multiplepumps or blowers are used equally.24 V DC supply option MCB 107The option is used to connect an external DC supply tokeep the control section and any installed option activewhen mains power is down.• Input voltage range: 24 V DC +/- 15% (max. 37 Vin 10 s).• Maximum input current: 2.2 A.• Maximum cable length: 75 m.System Integration Design Guide68 Danfoss A/S © 09/2014 All rights reserved.
