◎Terminal Block Identification for External Connections
1. Power cannot be supplied to the transmitters of certain flowmeters, such as the
Thermistor Type Vortex Flowmeter, DC Power Type Coriolis Flowmeter, etc.
Prepare a power source separately, or relay it using another device.
2. An asterisk (*) indicates requirement for a separate power source.
