E2271A 4x4 Matrix Switch Wiring Information
MAXIMUM VOLTAGE/CURRENT: The maximum voltage
that may be applied to any connector on the E2270A,
E2271A, or E2272A is 200 VDC, 125 VAC rms, or 175 VAC
peak. These limits apply only if the product is installed
in a humidity-controlled (<60% RH) environment where
airborne contaminants and transients are controlled,
and there is NOT a relay connection made to power
mains. If these conditions CANNOT be maintained, then
the maximum voltage is 60 VDC, 48 VAC rms or 68 VAC
peak.
The maximum current (non-inductive) that may be
applied to the E2270A, E2271A, or E2272A is:
Per Switch: 2 ADC, 2 AAC peak
Per M-Module: 8ADC, 8AAC peak
