Yokogawa YTA70P Temperature Transmitter Panel mount type DIN rail mount
The YTA70P is a Panel mount type of temperature transmitter that accepts thermocouples, RTDs, ohms or DC millivolts input and converts it to a 4 to 20 mA DC signal for transmission. The YTA70P conforms to the standard DIN rail mounting. The YTA70P supports HART® communication protocol. HART protocol revision is HART 7, and it features long tag number up to 32 characters, enhanced burst mode and event notification, and command aggregation function.
The YTA70P delivers the characteristics of both converters and transmitters. It has a space-saving design that offers low cost installation. The HART® 7 protocol allows you to conveniently configure the transmitter using the latest FDT/DTM technology. HART® 7 benefits include long tag, enhanced burst mode, and event notification. The YTA70P is the choice for rail-mounted control applications.
YTA70P features include:
- 4 to 20 mA DC Analog Output
- HART® 7 Digital Protocol Output
- 17 input types
- Rail-mount
