OTEK Corporation Signal Conditioner / Transmitter Model SCT

The SCT has an integral 5-28VDC / DC to DC converter. The 4-20mA transmitter accepts 0-1 VDC full scale signal from your sensor convert it to a 4-20mA process signal. The unit is ideal for logic power 5V systems where 24V is not available. Its high efficiency DC-DC converter requires ~ 170mA when the output is 20mA and can drive loads up to 1k Ohms (including your wire resistance). Note: The unit provides no I/O isolation, so care must be taken when using A.C. signals (Options 31-33) and avoiding “ground loops (engineer’s nightmare). Use this unit for power input applications of 4-6VDC.
