OPAL-MM
8 optoisolated Inputs + 8 relays

• 8 optoisolated digital inputs
• 8 spot relay (form C) outputs
• DC inputs 3 - 24V
• AC inputs 3 - 24V, 40Hz or greater
• Long lifetime relays (10,000,000 operations)
• 500VAC or DC isolation between board and signals

DESCRIPTION

SPECIFICATIONS

Opal-MM features 8 optoisolated digital inputs and 8
relays. The inputs accept signals ranging from 3-28V AC or
DC. An on-board input filter circuit allows the sensing of
AC inputs with frequencies of 40Hz or higher. This filter is
individually selectable for each input channel.
The 8 relays are non-latching type SPDT (form C). Each
relay has 3 contacts: Common (C), Normally Open (NO),
and Normally Closed (NC). For safety and reliability, all
relays retain their power-off state (C connected to NC)
during power-up and return to it during system reset. The
relays can switch both AC and DC voltages. Relay lifetime
is 1,000,000 operations minimum at rated DC load. Quick
actuation time (5ms operate or release), break-beforemake operation, and bifurcated contacts ensure reliable
operation even with low-level signals.
Opal-MM provides 500V DC or AC isolation between all
I/O connections and the rest of the board. This specification does not apply between I/O channels, although all
channels are isolated from each other as well. In many
applications, the I/O points share a common power or
ground line and require only isolation between the I/O
lines as a group and the control circuitry.
