1. General Information & Product Overview

️· What it is: The KPE series is a signal converter. It takes an analog input signal (voltage or current) and converts it into a standard output signal.
️· Purpose: To isolate, condition, and transmit signals reliably.
️· Manufacturer: M-System (Japan)
️· Datasheet Revision: ES-3545 Rev. 2
️· Website: [http://www.m-system.co.jp/](http://www.m-system.co.jp/)

2. Ordering Information & Model Codes (Important for Selecting the Right Model)

The model code is built from several parts. The basic structure is: `KPE - [Input Type] - [Output Type] - [Options]`

️· Input Types (Section 2, "[Input Type]"):
- `6`: 0 - 300 V DC
- `5`: 0 - 150 V DC
- `6`: 0 - 300 V DC
️· Output Types (Section 2, "[Output Type]"):
- `A`: 4 – 20 mA DC
- `B`: 2 – 10 mA DC
- `C`: 1 – 5 mA DC
- `D`: 0 – 20 mA DC
- `E`: 0 – 16 mA DC
- `F`: 0 – 10 mA DC
️· Options: (Not explicitly listed in the options table, but implied by the datasheet - these would be further code additions)

3. Input Specifications (Section 3)

️· Frequency: 50 or 60 Hz
️· Input Burden: 1 VA (Volt-Ampere - a measure of power)
️· Operational Range: 0 – 120 % of the input range. (The converter can handle signals slightly above the nominal maximum value)

4. Output Specifications (Section 4)

️· DC Current Output Examples:
- 0 – 20 mA DC (Load Resistance: 600 Ω max)
- 4 – 20 mA DC (Load Resistance: 600 Ω max)
- and others listed in the output types.
️· DC Voltage Output examples (from the first page)
- -10 – +12 V DC
- Minimum span : 5 mV
- Load resistance: 10 mA max; 5 mA for negative voltage output

5. Performance Characteristics (Section 5)

️· Accuracy: ±0.2 % (of the input range) – This is how much the output signal deviates from the true input value.
️· Response Time: ≤ 1 second (to reach a stable output)
️· Ripple: 0.5 % (of the output signal - a measure of noise)
️· Line Voltage Effect: ±0.1 % (how much the output changes with changes in the power supply voltage)
️· Insulation Resistance: ≥ 100 MΩ (a measure of how well the converter resists leakage current)
️· Dielectric Strength: 2000 V AC (voltage that can be applied before insulation breaks down)
️· Impulse Withstand Voltage: ±5 kV (peak – ability to withstand short voltage spikes)

6. Installation & Physical Characteristics (Section 11)

️· Mounting: Surface or DIN Rail
️· Weight: 350 g (0.77 lb)
️· Dimensions: (Refer to the dimensional diagram – not described in text, visually presented)

7. Electrical Connections (Section 12)

️· Shows a schematic diagram of the connections (Power Supply, Input, Output, Fuse) - *Refer to the diagram for details.*

Key Takeaways & Notes

️· Load Resistance: Pay close attention to the maximum load resistance specified for each output type. This is the maximum resistance the load connected to the output can have without affecting accuracy.
️· Power Supply: The datasheet doesn't explicitly state the power supply requirements for the KPE series itself.
️· Fuse: The presence of a fuse indicates overcurrent protection.
️· Application: These converters are likely used in industrial automation, process control, and similar applications where signal isolation and conversion are needed.
