Seneca K-Line Universal Transmitters

The K121 is Seneca's brand new universal converter/isolator, and is suitable for RTD, thermocouple, Ohm, V and mA conversions. In case of mA/V inputs, start and full scale can be settled with the following limits: ±24mA and ±30V. The device is supplied over the 4-20mA signal output (loop powered) and can only be configured using the free Easy LP software (or using the S117P kit). In some ways the K121 could even be seen as an inexpensive alternative to the Z109REG2.

From the compact, DIN-Rail mount box of the K121 you can achieve almost infinite applications, whilst also reducing your wiring as both the output and the power supply utilise the same circuit. The K121 is used to read different sensor types by a PLC analogue input card with built in power supply.
