1. Panel meter M40-A
AC voltage and AC current meter 96
x
48
mm (1/8 DIN) for panel mount
Panel meter 96 x 48 mm (1/8 DIN) for AC voltage and AC current sig-
nals. reading with 4 digits scalable to ±9999 with selectable decimal
point position. Measure in True RMS. Measure category CAT-II and
CAt-III. AC voltage measure up to 600 Vac, and AC current measure up
to 5 Aac. Signal measure coupling mode selectable in ‘AC’ or ‘AC+DC’.
Options for output and control with 1, 2 and 3 relays, isolated analog
outputs, communications in Modbus RTU, RS-485 ASCII and RS-232.
Special options with 4 and 6 relay outputs.
Independent alarms configurable as maximum or minimum, with 1
or 2 setpoints per alarm, hysteresis, independent activation and de-
activation delays and control for inverted relay.
Front protection IP54 with optional IP65. Connections by plug-in
screw terminals. For industrial applications.
