Voltage Ratings
Channels 0,1, and 11 are rated at 300V dc or ac rms maximum from a channel terminal
to earth and from a channel terminal to any other channel terminal.
Channels 2 to 10 and 12 to 20 are rated at 150V dc or ac rms maximum from a channel
terminal to any other channel terminal within channels 2 to 10 and 12 to 20.
IEC Overvoltage Category II.
Size
9.3 cm high, 21.6 cm wide, 31.2 cm deep
Weight
Net, 2.95 kg
Shipping, 4.0 kg
Power
90V to 264V ac (no switching required), 50 and 60 Hz, 10 VA maximum
9V dc to 16V dc, 10W maximum
If both sources are applied simultaneously, ac is used if it exceeds approximately 8.3
times dc.
Automatic switchover occurs between ac and dc without interruption.
(At 120V ac the equivalent dc voltage is ~14.5V).
Standards
IEC 1010-1, ANSI/ISA S82.01-1994, CSA-C22.2 No.1010.1-92, and EN61010-1:1993.
Complies with EN 50081-1, EN 50082-1, Vfg. 243/1991 and FCC-15B at the Class B
level, when shielded cables are used.
