Model Wise Description
PTX-3000-U - Process Transmitter with universal input (8 user selectable)
PTX-3000-F - Process Transmitter with single fixed input
PTX-3000-T - Process Transmitter with two same input
J,K,R,S,B thermocouple or RTD (Pt-100) or mV, mA signal (Input type not listed here can also be provided)
Full range of the selected input desired measuring range can be chosen from range selection table..
Software linearized to +/-1 oC for thermocouple input and +/-0.1oC for Pt-100 input.
For Voltage and Current the accuracy is absolute to the input.
24VDC +/- 10% @ 150mA
Current Output 1
4-20mA proportional to the specified range of the user selected input. (12 bit resolution). 2 wire
Current Output 2
4-20mA proportional to the specified range of the second specified input. (12 bit resolution). For PTX-3000-T
Digital Serial Output
Isolated 2 wire RS485 on MODBUS RTU protocol in SLAVE mode
4-20mA and RS485 outputs are isolated from DC Power supply.
Isolation voltage > 1.5KV DC.
RLmax = 400 Ohms - for each output.
4 digit - 0.3 red seven segment LED .
4 digit each for PTX-3000-T
2 or 3 wire for sensor input, 2 wire for DC supply and
2 x 4-20mA for current outputs, 2 wire for RS-485 outputs.
Through suitable size gland for supply and input/output.
ABS plastic IP-65 (120 x 80 x 55) mm.
