1. General Introduction The LS-TD4015 is an industrial grade standard RTD acquisition
product that supports PT100, PT1000, Cu50, Cu100, Ge53, BA1, BA2,
R5000 and R500 6-channel three-wire RTD inputs. RS485 interface is
optoelectronic isolated. AD acquisition part is also modulus
optoelectronic isolated. It adopts standard MODBUS RTU protocol.
Complaint with industry standards, LS-TD4015 is suitable to use for
a variety of industrial applications and automation systems. It is
convenient to communicate with the host computer and realize a
rapid networking and build your monitoring system. Thermal resistance supports: | PT100 | -200~850℃ | BA1 | -200~650℃ | | PT1000 | -200~850℃s | BA2 | -200~650℃ | | CU50 | -50~150℃ | R5000 | 0~5000Ω | | CU100 | -50~150℃ | R500 | 0~500Ω | | Ge53 | -50~150℃ | | |
