Configurable DC Input / DC Output Signal Isolator

POA excl. VAT

WAS4 PRO DC/DC Details

The configurable WAS4/WAZ4 PRO DC/DC: a U/I- DCsignal isolating converter with external power supply in 12.5 mm width, for transmitting and isolating analogue DC current signals (±0.1...±100 mA) and voltage signals (±20 mV...±200 V). 

Up to 440 fixed input and output parameters can be configured using the DIP switches and potentiometer (span/offset). The input/output channels and power supply are completely isolated with 4 kV. 

Because of its 20...253 VAC/DC wide-range power supply, the PRO DC can be used in many applications regardless of its position. 

The signal isolating converter features an adjustable transmission frequency (10 Hz/10 kHz), low power dissipation, and a wide temperature range (-10 °C to +70 °C). 

The WAVETOOL software can be used as a universal setting aid.The WAVETOOL software found at can be used for configuration. The PRO DC is optionally available with screw or tensionclamp wire connections. The signal isolating converter has international approvals (cULus, cULusEX, ATEX Zone2, GL) which enable it to be used worldwide for many explosive-risk applications.
