4 Output specifications
| Output type | Specification |
|---|---|
| Analog output | DC4～20mA 0～550Ω DC1～5V 600Ω～∞ MAX.4CH |
| Pulse output | Active energy or Reactive energy DC125V, AC125V 0.1A MAX.2CH |
| Relay output | Upper alarm or Lower alarm AC250V 5A DC100V 0.3A, DC30V 5A MAX.2CH |
| Transmission output | RS-485 Protocol: MODBUS Baudrate: 2400, 4800, 9600, 19.2k, 38.4kbps |
Up to two point outputs are available for pulse output and alarm output.
Either of transmission output and pulse output (alarm output) is to be selected (see type name system).
Pulse output is output asynchronously with the display update interval.
Note that a time difference may be generated between the indicated value and the pulse number.
5 Remote input specification
The measurement items of the main display can be changed by applying a voltage from outside (Display screen 1 or Display screen 2).
Apply a voltage of 80 to 264 VAC or 80 to 143 VDC to the external input terminal (for 0.5 seconds or more). Each time a voltage is applied, the next item is selected.
