APPENDIX A: CONNECTORS
MAXIMUM VOLTAGE/CURRENT. The maximum voltage
that may be applied to any connector on the M218, M219, or
M220 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 M218, M219, or M220 is:
Per Switch: 2 ADC, 2 AAC peak
Per Module: 8 ADC, 8 AAC peak
