This signal conditioner provides the galvanic isolation between field circuits and control circuits. The device transfers the status of 2-wire and 3-wire sensors to the relay contact output. The device has 2 inputs and 2 relay contact outputs. The device can be used either as dual channel signal conditioner or as a two-point level controller. The device is easily configured by the use of DIP switches. A fault is signalized by LEDs.
