YOKOGAWA SCP451-51 S1 Signal Conditioner | Isolator, 4-20mA, 2-Wire, DIN Rail, IP20

YOKOGAWA SCP451-51 S1 conditioner specifications. 2-wire signal isolator, 4-20mA input/output, 24V DC, DIN rail mount, for signal conditioning.

Product Overview

The YOKOGAWA SCP451-51 S1 is a 2-wire signal conditioner and isolator from the SCP400 series. It provides galvanic isolation and signal conversion for 4-20mA current loops. The unit is loop powered, meaning it derives its operating power from the input signal, and reproduces a proportional, isolated 4-20mA output signal. It is housed in a compact, DIN rail-mountable enclosure for easy installation in control panels.
