Selection Guide/Purchasing Recommendations

Choose this ABB 81EU01+GJR2391500R1210+81EU01E-E set.First,check the”PLC Model”:If you have an ABB AC 500 or AC 800M PLC and need up to 16 digital inputs and up to 4 analog outputs,such as for chemical reactors or automotive assembly lines,this set is perfect.If you need more than 16 inputs,add the 81EU02(32 digital inputs).If you need more than 4 outputs,add the 81EU02E-E(8 analog outputs).Don’t force a combination,as this will cause signal delays.Let’s look at the”Signal Type”section:If you need to acquire digital signals(such as switches and sensors)and send analog commands(such as valve control and motor control),this set is perfect.If you only need digital signals,buy the 81EU01 and GJR2391500R1210 separately.If you only need analog signals,buy the 81EU01E-E and GJR2391500R1210 separately.Buying the set is more cost-effective,saving 15%over buying them separately.

Don’t buy”refurbished”parts!The 81EU01’s isolation chip,the 81EU01E-E’s DAC chip,and the GJR2391500R1210’s gold-plated terminals are all made from old materials.The 81EU01 will miss signals,and the 81EU01E-E’s accuracy will be inaccurate.A customer previously bought a refurbished set,and after just one month,their reactor overpressured,resulting in a loss of 80,000 yuan.I recommend finding a reliable supplier,such as Shenzhen Changxin[www.cnplcdcs.com].We only sell genuine,original products,and each unit has a checkable serial number,ensuring peace of mind.

FAQ

Q:Can the 81EU01 be plugged into another brand’s docking station,such as a Siemens docking station?

A:Don’t try!The 81EU01 requires the GJR2391500R1210.Other brands’docking stations have different pin assignments and power supply methods,and plugging them in will burn out the module.A customer previously used a Siemens docking station to plug in the 81EU01,and it burned out as soon as power was applied,costing them 800 yuan.The original manufacturer’s setup is the most reliable.

Q:What load can the 81EU01E-E handle with a 4-20mA output?A:It can handle a maximum load of 500Ω.For example,the coil resistance of a typical control valve is typically 200-300Ω,which is no problem.If the load exceeds 500Ω,a signal amplifier must be added to prevent current loss.One customer didn’t add an amplifier,resulting in a loose control valve.Adding an amplifier fixed the problem.

Q:Can the GJR2391500R1210 be used with both the 81EU01 and 81EU01E-E modules?

A:No!Each base can only accommodate one module.The GJR2391500R1210 is a single-module base.To use both the 81EU01 and 81EU01E-E modules,you need to purchase two bases and mount them side by side on the DIN rail.A customer previously wanted to save on bases and installed two modules,ultimately burning both the module and base.Don’t save money.

Q:Can the kit be used in a workshop with a-15°C temperature?A:The minimum operating temperature for the 81EU01 and 81EU01E-E is-10°C.-15°C will damage the isolation chip.The GJR2391500R1210 can withstand-20°C,but the module cannot.We recommend adding a heater to the control cabinet to raise the temperature above-10°C.A northern power plant did this in winter and the system lasted three years without any problems.However,if used relentlessly,the module would fail after just one month.
