2. Temperature Control Output to MDR Coil Input Please refer to the Field Coil Power Requirements when selecting the correct temperature control output Example An HG35 1LD3 X000 requires 224mA to energize the coil and could be used with Watlow temperature control output options B or K i e 988A XXBB XXXX or 988A XXKK XXXX models The best selection is the B output option because it includes an RC snubber across the output If you select the K option it is recommended that you also purchase a Quencharc snubber separately Watlow part number 0804 0147 0000 Place the snubber across the MDR coil terminals to protect the temperature control solid state output When placing the snubber across the coil of a 2 and 3 pole relay you may have to add some lead wire to the snubber The MDR coil is an inductive load and the snubber will reduce the flyback voltage produced by the MDR coil when it de energizes See below IAW eparately Note Watlow temperature control solid state outputs will not drive VDC coils directly Refer to the coil current specifications above and any temperature control output specifications as required by the application Watlow Series HG Mercury Displacement Relay User s Manual 4 Ordering Information WMDR XMNN 1099 HG 00 UT TUT CI Amperage 30 30 Amp 35 35 Amp 50 50 Amp 60 60 Amp 80 80 Amp 1M 100 Amp 2M 150 Amp Coil Voltage 1 120V ac 4 2
3. 1 25 times the connected load or the next size above but do not exceed 1 6 times the MDR rating To fuse the MDR field coil you can use Bussmann fuse number MDL 2 for coils up to 240V ac For coils up to 480V ac use Bussmann fuse number JJS 1 Watlow Series HG Mercury Displacement Relay User s Manual consider the HG60 model if larger gauge or multiple wires are required See the load termination specification above lt gt WARNING Install high or low temperature control protection in systems where an overtemperature or undertemperature fault condition could present a fire hazard or other hazard Failure to install temperature control protection where a potential hazard exists could result in damage to equipment and property and personal injury or death 6
