NOTE: Each PCM document probably is outdated as to the OPTO22 Relays that it supports. You will need to read the documentation in order to find the maximum current and voltage each PCM can stand.
NOTE: It is not clear what the final supported Relay list was or is.

PCM1 Module Different variant
PCM1-Remote Card uses Opto 22 OAC5 AC Output, 3A, 12-140v, 5VDC Logic
CAUTION: Each Channel on the PCM1 assembly can control circuits at a maximum of 140V AC, 3A. Exceeding these values may cause damage to the unit.
Beginning with DOM1 rev D, PCM1 rev D, and PCM2 rev D, a power-on reset circuit holds digital output lines off for approximately five seconds after power is applied. Output lines will not respond to programmed changes during this time. After the power-on reset period, the output lines will remain off until programmed to change state. This circuitry does not affect analog output lines.
Older revisions of the DOM1, PCM1, and PCM2 do not contain a power-on reset. Output lines may power up in a random state under some circumstances. Do not use older versions of these products where random output at power up is undesirable.
