1.0 IntroductionThe Universal RTD Module II (URTDII) is an electronicresistance-temperature detector accessory for the followingdevices:Table 1, Applicable DevicesMP3000 EMR3000MP4000 EMR4000FP6000 EMR5000IQ1000II ETR4000ETR5000The URTDII can be used to monitor as many as 12 RTDinputs, These inputs fall into four groups that consist of: sixmotor windings, two motor bearings, two load bearings,and two auxiliary RTDs.The URTDII can be programmed to accept any of the fol-lowing types of RTD inputs:• 100 ohm platinum• 100 ohm nickel• 120 ohm nickel• 10 ohm copperThe RTD type can be selected for each of the four RTDgroups. For example, The motor winding RTD inputs canbe programmed for 10 ohm copper and the motor bearingRTD inputs can be programmed for 120 ohm nickel.The URTDII can transmit its information to a protectivedevice using a fiber optic link. It can be mounted remotelyup to 122 meters (400 feet) from the protective devicewhen using the fiber optic link.The URTDII can also be used as a stand-alone devicethat communicates on a Modbus network. A bidirectionalRS485 port is provided on the bottom of the unit.2.0 Assembly DrawingThe URTDII dimensions are shown in Figure1.J2J10BRTD7C/MB1CRTD7+/MB1+RTD7-/MB1-ShieldRTD8C/MB2CRTD8+/MB2+RTD8-/MB2-RTD9C/LB1CRTD9+/LB1+RTD9-/LB1-ShieldRTD10C/LB2CRTD10+/LB2+RTD10-/LB2-RTD11C/AUX1CRTD11+/AUX1+RTD11-/AUX1-ShieldRTD12C/AUX2CRTD12+/AUX2+RTD12-/AUX2-PWR IN 2PWR IN 1S2S1J11J10ARTD6C/MW6CRTD6+/MW6+RTD6-/MW6-ShieldRTD5C/MW5CRTD5+/MW5+RTD5-/MW5-RTD4C/MW4/CRTD4+/MW4+RTD4-/MW4-ShieldRTD3C/MW3CRTD3+/MW3+RTD3-/MW3-RTD2C/MW2CRTD2+/MW2+RTD2-/MW2-ShieldRTD1C/MW1CRTD1+/MW1+RTD1-/MW1-Figure 1, Dimension Drawing2IL02602013E Universal Resistance TemperatureNovember 2010 Detector (RTD) Module IIIL02602013E - November 2010 - www.eaton.com
