EncoderWorks configures IVM78E-011KRR05I-0413 as a custom compatible replacement solution for explosion-proof 4-20mA multiturn analog feedback where Set 1 / Set 2 scaling, 13-bit singleturn basis, 4-bit multiturn range, KR terminal mapping, INOX grounding, and Ø10 mm clamping-flange coupling must remain aligned with the installed analog input channel. The failure boundary is not only the 10–30 VDC supply, but also analog current span, load resistance, ramp direction, programmed lower and upper measuring limits, GND reference, shield continuity, terminal sealing, and explosion-proof certificate scope. Typical production lead time: 15 working days.
This model is used where the controller reads shaft position as a scaled 4-20mA current signal rather than an SSI clock/data word, PROFIBUS node, Profinet device, CANopen object, EtherNet/IP assembly, or incremental pulse train. A compatible replacement must preserve the analog current range, Set 1 lower-limit function, Set 2 upper-limit function, 16-turn measuring capability, KR radial terminal execution, Ø10 mm shaft interface, stainless housing boundary, and hazardous-area installation requirement.
System Limits
The first system boundary is the 4-20mA scaling and analog input interpretation. IVM78E-011KRR05I-0413 must reproduce the same current span over the programmed measuring range, with lower and upper positions defined by the installed machine. If the replacement is supplied as 0-20mA, scaled over the wrong travel, programmed with reversed ramp direction, connected to an analog input with excessive load resistance, or reset unintentionally through Set 1 / Set 2, the PLC may still read a valid current while the machine position is wrong. Typical failures include compressed travel, shifted zero, inverted feedback, 3.6 mA underrange behavior, 22 mA overrange behavior, or unstable analog value near the end positions.
The second boundary is the KR terminal compartment, INOX grounding, and Ø10 mm clamping-flange installation. Terminal 1 GND, terminal 2 +Ub, terminal 4 Set 2, terminal 7 Set 1, terminal 8 analog output, grounding terminal, shield path, cable-gland sealing, stopping-plug sealing, and stainless housing bonding must match the installed wiring. A correct analog encoder can still fail if terminal 8 is not referenced to the same analog input ground, Set 1 or Set 2 is exposed to noise, unused terminals are treated as active signals, the shield is terminated with high impedance, or the cable gland does not preserve the sealing boundary.
Wiring & Installation
Before replacement, confirm the full installed model code, 4-20mA analog input requirement, load resistance, lower measuring limit, upper measuring limit, ramp direction, Set 1 / Set 2 programming method, KR terminal assignment, radial cable-entry direction, cable-gland condition, stopping-plug condition, INOX housing requirement, and Ø10 mm shaft interface. This 0413 version should not be inferred from 0412 variants because the singleturn basis and scaling expectation may be different at the analog input and commissioning level.
During installation, verify GND, +Ub, Set 2, Set 1, analog output, grounding terminal, shield continuity, and analog input reference before powering the system. Keep analog wiring away from motor and drive cables, avoid cable kinking or tensile load at the gland, and do not trigger Set 1 or Set 2 unless the measuring range is being intentionally programmed. The clamping flange should seat flat, and the coupling should not force the Ø10 mm shaft off center. Explosion-proof suitability must be confirmed against the installed hazardous-area requirement and certificate scope before shipment.
