Transformer monitoring device UP4x series

Modbusdigital

UP4х series compatible with analogue outputs “Current loop” designed for work with the drives: • MR, EM and ED-S; • MZ-2, MZ-4 with replacement of a standard resistive sensor by the digital sensor of drive position monitor DP4 manufactured by ANTRAKS equipped by analogue output “Current loop”; • PDP-4 and others motor drivers designed for use with selsyn sensor. Selsyn sensor in this case shall be replaced by tap position sensor DP3 with analogue output “Current loop”; • Other motor drives with resistant sensors with analogue output “Current loop” (0-5mA, 0-20mA or 4-20mA). UP Monitors family contains a number of devices, form very simple models suitable for solving particular problems to complex multifunctional devices that can be employed anywhere. Using our devices one can receive position information from any type of OLTC and transmit it via digital or analog outputs. • Alarm of boundary, first and last taps of drive position (UP23, UP25, UP31 and UP41); • Additional discrete outputs for signals about following events: first or last drive’s tap are reached, tap switching, reaching of boundary tap position (UP23, UP25, UP31 and UP41); • Digital output RS-485 (RS-232), used by the MODBUS RTU/ASSII Protocol, allows you to transmit information about the position of the OLTC drive to SCADA and configure the device when connected to a computer; • Additional analogue output “Current loop” (0-5mA, 0-20mA or 4-20mA) for transmission of information on drive to SCADA position (UP23, UP25, UP31 and UP41);
