PEARL-MM
Relay Output PC/104 Module
• 16 SPDT (form C) relays
• Long lifetime - 100,000,000 operations
• 500VAC/DC isolation between board and
signals
• Pin headers for user connections

DESCRIPTION

SPECIFICATIONS

Pearl-MM is a PC/104 format industrial control module
with 16 relays. The relays have SPDT (form C) conguration. Each relay has 3 contacts: Common, Normally
Open, and Normally Closed. For safety and reliability, all
relays are in their power-o state (Common connected
to Normally Closed) at power-up or system reset. The
relays can switch both AC and DC voltages. They feature
long life (100,000,000 operations), quick actuation time
(4ms max operate and release), and superior isolation
(500V AC or DC).

Relay Circuit
Pearl-MM has 16 relay outputs with SPDT (form C)
design. Each relay has a common (C), normally open
(NO), and normally closed (NC) contact. The relays are
controlled with two 8-bit control registers and have have
break-before-make operation to prevent shorting.
